The EON (1064nm laser) is intended for non-invasive lipolysis of the abdomen, flanks, back, and thighs to achieve disruption of adipocyte cells intended for non-invasive aesthetic use to achieve a desired aesthetic effect. It is intended for individuals with a Body Mass Index of 30 or less.
EON aesthetic laser system is 1064nm diode laser device that is intended for non-invasive lipolysis of the abdomen, flanks, back, and thighs in individuals with a Body Mass Index (BMI) of 30 or less. This wavelength is used to affect the appearance of visible fat bulges in the abdomen and flanks.
Both laser energy and cooling air are delivered concurrently through the same treatment head that is positioned and moved over the skin at a fixed height by a robotic arm. The treatment head is never in contact with the skin.
During treatment, the desired area will be defined by the physician and will be treated with the 1064nm laser over a 20-minute timeframe. The mechanism of action is to preferentially heat the adipose tissue to temperatures that will induce apoptosis (>42°C). The cooling system will maintain the skin at comfortable temperature (<43°C).
The provided text describes a 510(k) premarket notification for the EON aesthetic laser system. The submission, K222226, seeks to expand the indications for use of the EON device to include the thighs and back, in addition to the previously cleared abdomen and flanks.
The documentation focuses on demonstrating substantial equivalence to a predicate device (K211681), which is also the EON system but with a more limited indication for use.
Based on the provided text, the information regarding acceptance criteria and the study proving the device meets these criteria is very limited and primarily relies on literature support rather than a de novo clinical study with specific acceptance criteria.
Here's an attempt to extract the requested information, highlighting what is provided and what is not provided:
Acceptance Criteria and Study for EON (K222226)
The EON device is a low-level laser system intended for non-invasive lipolysis. The current submission (K222226) is an update to a previously cleared device (K211681 and K180511), seeking to expand its indications to include the thighs and back.
The primary method used to demonstrate device performance and substantial equivalence for the expanded indications is via literature review and justification, rather than a new, dedicated clinical study with pre-defined acceptance criteria for the new treatment areas. Therefore, explicit "acceptance criteria" in the traditional sense of a clinical trial (e.g., statistical thresholds for efficacy endpoints) are not presented for this specific submission for the new treatment areas. Instead, the "acceptance" is based on inferring equivalent safety and effectiveness from existing data and the predicate device.
1. Table of Acceptance Criteria and Reported Device Performance
As specific numerical acceptance criteria for clinical efficacy for the new indications (thighs and back) are not provided in this document, the table reflects the regulatory claim of substantial equivalence and relies on the performance of the predicate.
| Parameter/Criteria | Acceptance Criteria (Implicit for Substantial Equivalence) | Reported Device Performance (as inferred for expanded indications) |
|---|---|---|
| Safety Profile | Similar or better safety profile than predicate device. | "The clinical justification concluded that the performance of EON in the proposed areas (back and thighs) has a safety and effectiveness profile that is similar to its performance in the previously cleared areas." The device maintains a cooling system to keep skin temperature <43°C during treatment. |
| Effectiveness | Similar or better effectiveness profile (lipolysis resulting in desired aesthetic effect) than predicate device. | "The clinical justification concluded that the performance of EON in the proposed areas (back and thighs) has a safety and effectiveness profile that is similar to its performance in the previously cleared areas." The mechanism of action (preferential heating of adipose tissue to >42°C to induce apoptosis) is consistent across all indicated areas. |
| Operational Parameters | Identical technical specifications to the predicate device. | Identical: Laser Type (Diode), Wavelength (1064 nm), Power Mode (CW), Pulse Length (1-20s), Applicator Size (75, 110, 150 cm²), Application Method (Articulated Scanning Arm, Non-contacting), Max Power Density (Up to 1.4 W/cm²), Supply Voltage (110V; Single Phase), Supply Current (20A), Laser Cooling (Closed cycle, internal). |
| Intended Use Population | Same BMI (<=30) as predicate device. | "Intended for individuals with a Body Mass Index of 30 or less." |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not applicable. No new specific clinical test set was used for the expanded indications. The FDA submission relies on "Literature" to support the addition of thighs and back. The sample size for the original studies that supported the predicate device (K211681, K180511) is not detailed in this document.
- Data Provenance: "Literature was used to support the addition of the two proposed areas (thighs and back)." The specific origin (country, retrospective/prospective) of this literature is not specified in the provided document.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
Not applicable. No new specific test set requiring expert ground truth establishment for the expanded indications (thighs and back) is described in this document. The reliance is on existing literature and the established performance of the predicate device.
4. Adjudication Method for the Test Set
Not applicable. No new specific test set is described.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No. An MRMC comparative effectiveness study is not mentioned or described in this document. The submission relies on demonstrating substantial equivalence based on technical specifications and existing literature/predicate performance.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) was Done
Not applicable. The EON is a physical laser device, not an AI algorithm. Its performance is directly tied to its physical operation rather than an independent algorithm.
7. The Type of Ground Truth Used
The "ground truth" for the expanded indications (thighs and back) is implicitly established through published literature regarding the efficacy and safety of similar laser lipolysis technologies and the known performance of the EON device in previously cleared indications (abdomen and flanks). It is not based on pathology or specific outcomes data from a new trial for these expanded areas within this submission document.
8. The Sample Size for the Training Set
Not applicable. This device is a physical laser system, not an AI/ML algorithm that requires a "training set" in the computational sense.
9. How the Ground Truth for the Training Set Was Established
Not applicable.

- Data Provenance: Confirmed positive SMA samples (molecular genetic testing result showing homozygous deletion of SMN1 exon 7) and presumed negative DBS samples matched by storage time.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document mentions that the clinical status of the routine subjects in the Clinical Screening Study was determined through a "retrospective review by clinical experts." However, it does not specify the number of experts or their specific qualifications (e.g., "radiologist with 10 years of experience"). For the confirmed SMA cases, "confirmatory test results" (molecular genetic testing) were used as the comparator, which is a definitive method rather than expert consensus on imaging.
4. Adjudication Method for the Test Set
The document does not describe any specific adjudication method (like 2+1 or 3+1) for the interpretation of results in the test sets. For the Eonis SCID-SMA kit, the interpretation of results appears to be largely automated by the Eonis Analysis Software based on pre-set Ct cut-off values. For the clinical screening study, samples with values above the cut-off were re-tested in duplicate to obtain the final result.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not performed. This device is a quantitative PCR-based assay with automated interpretation software, not an imaging-based AI system that assists human readers. Therefore, the concept of human readers improving with AI assistance is not applicable here.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, the performance of the Eonis SCID-SMA Kit is essentially standalone. The Eonis Analysis Software "automatically flags quality control (QC) violations and interprets results according to the cut-offs," presenting results as "Presumptive Positive" or "Presumptive Normal." While human operators perform the lab procedures (DNA extraction, PCR setup), the final interpretation of the test result itself is automated by the algorithm based on the measured Ct values against a pre-set cut-off.
7. The Type of Ground Truth Used
- Analytical Studies (Precision, Reproducibility, Limit of Blank, Interference, Method/Extraction Equivalency, Carry-over): Ground truth was based on the contrived nature of the samples. For example, SMA positive samples were created by spiking specific cells, and analyte-negative samples were prepared to contain no target analyte.
- Clinical Screening Study:
- For SMA positive cases (51 samples): Ground truth was established by "confirmatory test results" (molecular genetic testing showing homozygous deletion of SMN1 exon 7).
- For routine newborn screening specimens (3018 samples): Ground truth was established by "retrospective review by clinical experts to confirm the routine subject cohort samples were from unaffected individuals." This suggests a form of clinical outcome/diagnosis as ground truth, likely based on further clinical evaluations, not just genetic testing for SMN1 deletion.
- Accuracy Study:
- For confirmed SMA samples (51 samples): Ground truth was "molecular genetic testing result showing homogenous deletion of SMN1 gene exon 7."
- For presumed negative samples (55 samples): Ground truth was confirmed by "molecular genetic testing for SMN1" using a CE-IVD labeled assay. This is molecular genetic testing/pathology ground truth.
8. The Sample Size for the Training Set
The document does not explicitly state a separate "training set" for the Eonis SCID-SMA Kit. As a PCR-based assay, its "learning" primarily involves setting the appropriate Ct cut-off value (31.24). This cut-off is pre-set in the Eonis Analysis Software. The document does not describe how this specific cut-off was initially determined (e.g., through a separate study for calibration or training). The studies described here are verification and validation studies to demonstrate the performance with that pre-set cut-off.
9. How the Ground Truth for the Training Set Was Established
Since a distinct "training set" is not explicitly mentioned for algorithmic development in a machine learning sense, the establishment of ground truth for training is not detailed. The inherent "training" of such a system would involve optimizing the Ct cut-offs based on a set of known positive and negative samples to achieve desired diagnostic sensitivity and specificity. However, the provided text focuses on the validation of the device's performance given its pre-determined operational parameters (like the 31.24 Ct cut-off).

The Eonis™ SCID-SMA kit is intended for the semi-quantitative determination of TREC (T-cell receptor excision circle) as an aid in screening newborns for Severe Combined Immunodeficiency (SCID) and for the semi-quantitative determination of KREC (Kappa-deleting recombination excision circle) as an aid in screening newborns for X-linked agammaglobulinemia (XLA). The test is intended for DNA from blood specimens dried on a filter paper and for use on the QuantStudio™ Dx Real-Time PCR instrument.
This test is not intended for screening of SCID-like Syndromes, such as DiGeorge Syndrome, or Omenn Syndrome. lt is also not intended to screen for less acute SCID syndromes such as leaky-SCID or variant SCID. The test is not indicated for screening B-cell deficiency disorders other than XLA, such as atypical XLA, or for screening of XLA carriers.
This test is not intended for use as a diagnostic test and a positive screening result should be followed by confirmatory testing.
The Eonis SCID-SMA kit is a multiplex real-time PCR-based assay. It uses target sequence-specific primers and TaqMan™ probes to amplify and detect three targets: TREC, and RPP30, in the DNA extracted from newborn dried blood spot (DBS) using Eonis DNA Extraction kit in a single PCR reaction.
Each Eonis SCID-SMA kit contains reagents for up to 384 reactions (for 3241-001U) or 1152 reactions (for 3242-001U) including kit controls.
The document describes the Eonis SCID-SMA kit, a real-time PCR-based assay for newborn screening of Severe Combined Immunodeficiency (SCID) and X-linked agammaglobulinemia (XLA). The study provided demonstrates the device's analytical and screening performance to support its substantial equivalency to a predicate device.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" as a separate table. However, it presents Sensitivity and Specificity for both TREC and KREC analytes, which serve as key performance metrics. These values are compared to the predicate device.
Reported Device Performance of Eonis SCID-SMA Kit:
| Analyte | Metric | Percent | Confidence Limits |
|---|---|---|---|
| TREC | Sensitivity | 100 % | 80.5 % - NA |
| False-negative rate | 0 % | NA - 19.5 % | |
| Specificity | 99.7 % | 99.4 % - 99.9 % | |
| False-positive rate | 0.3 % | 0.1 % - 0.6 % | |
| KREC | Sensitivity | 100 % | 54.1 % - NA |
| False-negative rate | 0 % | NA - 45.9 % | |
| Specificity | 99.7 % | 99.4 % - 99.9 % | |
| False-positive rate | 0.3 % | 0.1 % - 0.6 % |
Comparison to Predicate Device (PerkinElmer EnLite Neonatal TREC Kit) for TREC:
| Analyte | Metric | Percent | Confidence Limits |
|---|---|---|---|
| TREC | Sensitivity | 100 % | 79.4 % - NA |
| False-negative rate | 0 % | NA - 20.6 % | |
| Specificity | 99.7 % | 99.4 % - 99.8 % | |
| False-positive rate | 0.3 % | 0.2 % - 0.6 % |
The reported performance clearly aims to meet or exceed the performance of the predicate device, demonstrating 100% sensitivity and high specificity for both analytes.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Screening Performance Study (Test Set):
- Total DBS specimens: 3090
- Confirmed SCID positive: 17
- Confirmed XLA positive: 6
- Normal newborn screening specimens: 3018 (retrospective archived)
- Data Provenance: Retrospective archived dried blood spot specimens.
- Country of Origin: US and Denmark.
- Study conducted in Denmark.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Number of Experts: Not explicitly stated as a specific number. The document mentions "clinical experts" were used.
- Qualifications of Experts: The document states "clinical experts" retrospectively reviewed the clinical status of routine subjects to confirm they were from unaffected individuals. Further specific qualifications (e.g., specific medical specialty, years of experience) are not provided in this document.
4. Adjudication Method for the Test Set
- Adjudication Method: The document describes a retesting protocol for initial "screen positive" results.
- "The specimens having TREC and KREC levels below the cut-off values in the initial round of testing were re-tested in duplicate."
- "The final results (presumptive positive, invalid result) were classified after the second round of testing."
- This implies a form of internal re-adjudication based on duplicate retesting for samples near the cut-off. There is no mention of external expert adjudication for discordant results or a specific "X+Y" type of adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
- MRMC Study: No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This device is an in-vitro diagnostic (IVD) kit for semi-quantitative determination of biomarkers, not an AI assisting human readers of medical images. Therefore, the concept of human readers improving with AI assistance is not applicable to this type of device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Standalone Performance: Yes, the entire performance data regarding sensitivity, specificity, reproducibility, precision, limit of detection, and linearity are based on the standalone performance of the Eonis SCID-SMA kit (the algorithm of the kit combined with the instrument) on dried blood spot samples. This device operates as an automated assay, therefore, its performance is inherently "standalone" in terms of its analytic and clinical validity.
7. The Type of Ground Truth Used
- Ground Truth Type:
- Confirmatory testing: For SCID and XLA positive cases, "Confirmatory test results were used as the comparator." This implies clinical diagnosis or gold standard laboratory tests.
- Clinical expert retrospective review: For normal newborn screening specimens, "The clinical status of the routine subjects was determined through a retrospective review by clinical experts to confirm the routine subject cohort samples were from unaffected individuals." This indicates clinical outcomes or medical records adjudicated by experts.
8. The Sample Size for the Training Set
- Training Set Sample Size: The document does not explicitly state the sample size of a separate "training set" for the assay. The study described is a clinical validation (test set). For assay development (which would include "training" for establishing parameters like cut-offs), the document mentions:
- Cut-off values were established using "an independent dataset." The size of this independent dataset is not specified.
- Reproducibility and precision studies used panels of dried blood spots at different TREC/KREC levels, but these are for analytical validation rather than establishing classification criteria.
9. How the Ground Truth for the Training Set Was Established
- Training Set Ground Truth Establishment: As no specific "training set" is detailed, the method for establishing ground truth for any data used during the assay's development or cut-off determination (the "independent dataset" mentioned for cut-off study) is not explicitly described. However, it's reasonable to infer that similar methods to the test set ground truth (confirmatory testing for affected individuals and clinical review for unaffected individuals) would have been applied during the development phase.

The EON (1064nm laser) is intended for non-invasive lipolysis of the abdomen and flanks to achieve disruption of adipocyte cells intended for non-invasive aesthetic use to achieve a desired aesthetic effect. It is intended for individuals with a Body Mass Index of 30 or less.
EON aesthetic laser system is 1064nm diode laser device that is intended for non-invasive lipolysis of the abdomen and flanks in individuals with a Body Mass Index (BMI) of 30 or less. This wavelength is used to affect the appearance of visible fat bulges in the abdomen and flanks.
Both laser energy and cooling air are delivered concurrently through the same treatment head that is positioned by a robotic arm. The treatment head is never in contact with the skin.
During treatment, the desired area will be defined by the physician and will be treated with the 1064nm laser over a 20-minute timeframe. The mechanism of action is to preferentially heat the adipose tissue to temperatures that will induce apoptosis (42°C to 50°C). The cooling system will maintain the skin at comfortable temperature (<43°C).
Here's a breakdown of the acceptance criteria and the study details for the EON device, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Stated Objectives) | Reported Device Performance and Study Success |
|---|---|
| Primary Objective: Confirm safety of the 1064-nm laser device for non-invasive subcutaneous fat reduction in the flank area. | Low incidence of adverse effects (only 1 subject developed palpable thickening, resolved by Week 12). Mean pain score during procedure was 1.95 (0-10 scale), decreasing to 0.9 at 30 minutes post-procedure. |
| Primary Efficacy Endpoint: Blinded evaluation of pre- and post-treatment photos. Study success if at least two of three independent readers correctly identify at least 9 of 11 photo sets as pre-treatment. | 27 (81.8%) of 33 image sets were correctly scored overall. Two of the three readers correctly identified pre- and post-treatment photos in at least 9 of 11 subjects, thus achieving study success. |
| Secondary Efficacy Endpoint: Mean fat reduction by ultrasound. | At Week 12 after one treatment, the mean reduction in subcutaneous adipose thickness was 6.1 mm per flank and 12.1 mm per patient (-15%; p<0.01, both measures). |
| Secondary Objective: Assess extent of subject discomfort during treatment. | Mean pain score during procedure was 1.95 (0-10 scale), decreasing to 0.9 at 30 minutes post-procedure. |
| Secondary Objective: Assess overall subject satisfaction with the results of the procedure. | Subject satisfaction was "Excellent" for all subjects (100%). |
2. Sample Size Used for the Test Set and Data Provenance
The text doesn't explicitly state the total number of subjects enrolled in the clinical study, but it implies a minimum of 11 subjects for the blinded photo evaluation ("at least 9 of the 11 photos as pre-treatment"). For the "27 (81.8%) of 33 image sets" for blinded evaluation, this implies 33 image sets were evaluated, which likely corresponds to 33 subjects or 33 treatment areas. Considering the 12.1mm reduction "per patient," it refers to patient-level data.
The data provenance is prospective clinical study. The country of origin of the data is not specified in the provided text.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
Three independent readers were used for the blinded evaluation of pre- and post-treatment photos. Their specific qualifications (e.g., radiologist, years of experience) are not specified in the provided text.
4. Adjudication Method for the Test Set
The adjudication method for the blinded photo evaluation was 2 out of 3 concensus. The study was declared successful if "at least two of the three independent readers correctly identified at least 9 of the 11 photos as pre-treatment."
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No, an MRMC comparative effectiveness study involving human readers with and without AI assistance was not explicitly described in the provided text. The study involved a blinded evaluation by human readers, but it was for assessing the visual outcomes of the EON device itself, not to compare human reader performance with and without AI.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
The EON device is a laser system for lipolysis, not an AI-powered diagnostic tool. Therefore, a standalone (algorithm only) performance study in the context of diagnostic AI is not applicable and was not performed. The performance evaluation focuses on the efficacy and safety of the laser device itself.
7. The Type of Ground Truth Used
The ground truth used in the study included:
- Expert Consensus (implied): For the blinded photo evaluation, the consensus of at least two out of three independent readers served as the ground truth for identifying pre- and post-treatment images.
- Objective Measurements: Ultrasound measurements were used to objectively quantify subcutaneous fat reduction.
- Subjective Outcomes: Patient satisfaction surveys and pain scores were also collected.
8. The Sample Size for the Training Set
The provided text does not mention a training set specific to the EON device's clinical study. This is expected as the EON is a physical device (laser system) and not a software algorithm that requires a training set in the typical AI/machine learning sense.
9. How the Ground Truth for the Training Set was Established
As there is no mention of a training set for the EON device in the context of the provided clinical study description, this question is not applicable.

2. Sample Size Used for the Test Set and Data Provenance:
The document does not explicitly state the sample sizes for each specific test (e.g., how many gloves were tested for dimensions, tensile strength, barrier properties, or biocompatibility). However, it mentions that the tests were performed "according to the requirements of Guidance for Industry and FDA Staff - Medical Glove Guidance Manual" and specific ASTM and ISO standards. These standards typically specify the sampling plans and test methodologies.
The provenance of the data is not explicitly stated in terms of country of origin for the testing itself, but the manufacturer is EONS GLOVES (Thailand) Co., Ltd. The study type is non-clinical data, focusing on performance and biocompatibility rather than clinical trials.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This question is not applicable to this type of device and study. The "ground truth" for the performance and biocompatibility tests of medical gloves is established by the specified ASTM and ISO standards and their defined methodologies, not by expert consensus or interpretation of images/data by human experts. The results are quantitative measurements against predefined criteria in the standards.
4. Adjudication Method for the Test Set:
This question is not applicable. The performance testing involves objective measurements and adherence to specific standards. There's no human interpretation or adjudication process in the sense of consensus among experts for diagnostic output.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
This question is not applicable. This is a physical medical device (gloves), not an AI-powered diagnostic or interpretive tool. Therefore, MRMC studies involving human readers and AI assistance are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
This question is not applicable. This is a physical medical device. It does not involve an algorithm or AI.
7. The Type of Ground Truth Used:
The "ground truth" for evaluating the EONS Nitrile Examination Gloves Powder Free is based on:
- Established ASTM Standards: For physical properties and barrier properties (e.g., ASTM D6319-19, ASTM D3767-03, ASTM D412-16, ASTM D5151-06, ASTM D6124-06).
- Established ISO Standards: For biocompatibility tests (e.g., ISO 10993-1:2018, ISO 10993-5:2009, ISO 10993-10:2010, ISO 10993-11:2017).
- Guidance from Regulatory Bodies: Specifically, the "Guidance for Industry and FDA Staff - Medical Glove Guidance Manual."
These standards define the acceptable ranges and methodologies for testing, which serve as the objective performance criteria.
8. The Sample Size for the Training Set:
This question is not applicable. This device does not involve machine learning or AI, and therefore, there is no "training set." The tests are designed to evaluate the physical and biological characteristics of the manufactured product against established quality standards.
9. How the Ground Truth for the Training Set was Established:
This question is not applicable for the reason stated above.

Eon Aligners are indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e., all second molars). Eon Aligner System positions teeth by way of continuous gentle force.
The Eon Aligners is a custom clear aligner system. They are a series of doctor-approved clear plastic removable aligners that are used as alternative traditional orthodontic wires and brackets for the alignment of maloccluded or misaligned teeth. This series of aligner moves the teeth gently, and in small increments, from their original misalignment to their final treated position for improved dental alignment.
The Eon Aligner device is an orthodontic plastic bracket used for the treatment of tooth malocclusion in patients with permanent dentition. The provided text outlines the device's characteristics and the studies performed to demonstrate its substantial equivalence to a predicate device (Ormco Spark Aligner System, K182826).
1. Table of Acceptance Criteria and Reported Device Performance
The submission focuses on establishing substantial equivalence to a predicate device, rather than defining specific performance metrics typically found in AI/ML performance studies (e.g., sensitivity, specificity, AUC). Instead, the acceptance criteria are based on demonstrating equivalence in materials, manufacturing processes, intended use, operating principles, and biocompatibility.
| Acceptance Criteria Category | Reported Device Performance (Eon Aligner) |
|---|---|
| Intended Use | Eon Aligners are indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e., all second molars). Eon Aligner System positions teeth by way of continuous gentle force. This is identical to the predicate device. |
| Mechanism of Action | Orthodontic movement occurs by means of gentle forces applied on the teeth by the aligner, following a programmed movement approved by the dental health professional. This is identical to the predicate device. |
| Patient Population | Patients with all permanent dentition. This is identical to the predicate device. |
| Materials Used | Polyurethane-polyester copolymer resin. This is identical to the predicate device. |
| Sterility | Not supplied sterile. This is identical to the predicate device. |
| Wear at Night | Yes. This is identical to the predicate device. |
| Dental Health Professional Review | A dental health professional takes patient impressions/scans, sends them to the dental lab, reviews the treatment setup, and can reject or modify it before approval. Final aligners are dispensed by the dentist/orthodontist who monitors the patient's orthodontic movement. This workflow is described as similar to the predicate. |
| Biocompatibility | Passed all 11 listed biocompatibility tests (Cytotoxicity, Maximization Test for delayed-type hypersensitivity, Intracutaneous Reactivity Test, Oral Mucosal Irritation Test, Bacterial reverse mutation assay, In vitro mammalian cell TK gene mutation test, Skin irritation study, Skin sensitization test, Tests for systemic toxicity/Subchronic systemic toxicity test, In vitro mammalian chromosome aberration test). The device materials are identical to the predicate, and these tests confirm no adverse biological effects. |
| Manufacturing Workflow Validation | A manufacturing fit validation study in two parts: 1) established steps for aligners from manual impressions and digital scans. 2) Recreated 3D printed models and aligners from eight patients with successful malocclusion treatment. Results demonstrated minimal differences between digital inputs and final aligners, validating the workflow. |
2. Sample Size Used for the Test Set and Data Provenance
The manufacturing fit validation study used a sample size of eight (8) patients who had successfully undergone malocclusion treatment. The provenance of this data (e.g., country of origin, retrospective or prospective) is not explicitly stated in the provided text. It is assumed to be retrospective as it involved re-creating models from "successfully undergone malocclusion treatment."
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The text does not explicitly state the number of experts or their qualifications for establishing the ground truth for the manufacturing fit validation study. The study involved recreating 3D printed models and aligners based on "successful treatment," implying that the "ground truth" was the outcome of successful treatment as prescribed and achieved by a dentist/orthodontist. The process involves a "prescribing physician" reviewing and approving the treatment setup, suggesting ongoing expert involvement, but not a specific ground truth adjudication panel for the manufacturing validation.
4. Adjudication Method for the Test Set
The text does not describe an adjudication method (e.g., 2+1, 3+1) in the context of an expert review panel for the manufacturing fit validation study. The standard for "ground truth" in this context appears to be the successful outcome of malocclusion treatment for the eight patients. The validation aimed to show that the manufacturing process could accurately reproduce the digital plan, with differences being "minimal."
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
An MRMC comparative effectiveness study was not performed, nor is it applicable to this type of device submission. The Eon Aligner is a physical medical device (orthodontic plastic bracket), not an AI-assisted diagnostic or therapeutic tool for which human-reader performance would be evaluated. The submission focuses on demonstrating the physical and functional equivalence of the device to an existing predicate.
6. Standalone (Algorithm Only) Performance Study
A standalone performance study for an algorithm was not performed, as the Eon Aligner is a physical medical device. While the device relies on "dental software intended for tooth alignment" for its design, the submission focuses on the manufactured product and its biological interaction, not the performance of the software itself as a standalone diagnostic tool. The manufacturing workflow validation included aspects of the "design software" and "3D-Printing," validating the process of creating the aligners, not the interpretative accuracy of the algorithm.
7. Type of Ground Truth Used
For the manufacturing fit validation study: The ground truth was based on the successful outcome of malocclusion treatment in eight (retrospective) patients, where the 3D printed models and aligners were recreated to demonstrate that the manufacturing process could achieve the intended therapeutic outcome with minimal deviation from the digital plan.
For biocompatibility: The ground truth was established by standardized laboratory tests per ISO 10993 series and confirmed against the identical materials of the predicate device.
8. Sample Size for the Training Set
The text does not mention a training set in the context of an AI/ML algorithm. The "training" for this device would relate to the manufacturing validation and biocompatibility, not an algorithmic model.
9. How the Ground Truth for the Training Set Was Established
As there is no mention of an algorithm training set, this question is not applicable. The ground truth for the manufacturing validation was indirectly established by the successful treatment outcomes of previously treated patients. The "prescribing physician reviews and approves the treatment setup before the plastic trays are produced," implying that the clinician's approval of the treatment plan serves as the internal 'ground truth' for the design stage.

The EON Portable Reverse Osmosis Water Purification System is intended to be used as a dialysis accessory to produce water through reverse osmosis for use with hemodialysis equipment. EON can be connected to hemodialysis equipment used in hospitals, clinics and in home environments, in conjunction with the appropriate pre and post treatment units, as part of a water treatment system designed to meet current AAMI and Federal (U.S.) standards.
EON has optional heat disinfection cycles intended to disinfect the reverse osmosis (RO) machine and product loop, and connection tubing to the hemodialysis machine. EON's heat disinfect the connection tubing (heat forward cycle) is intended to be used only with hemodialysis machines which contain their own heat disinfection cycles and hence are able to tolerate high temperatures. EON is not intended to heat disinfect the hemodialysis machine.
The device is a portable water purification system which uses reverse osmosis to remove contaminants from water that is used to dilute dialysis concentrate to form dialysate for use in hemodialysis equipment. Feed water enters the unit and is directed through a pump into a RO membrane. The pump applies a high hydrostatic pressure that forces water from the concentrated (feed) side to the dilute (product) side of the RO membrane. As water flows across the membrane purified water is produced. Both subject and predicate devices are designed to maintain low microbiological levels in the flow pathway by using optional cycles which perform heat disinfection on the entire RO machine and loop. The subject device also has an optional Heat Forward cycle which is intended to heat disinfect the connection tubing to the hemodialysis machine.
The EON is capable of generating purified water that meets AAMI water quality requirements for hemodialysis. It must be used with appropriate pre and post treatment units, including at a minimum carbon adsorption media pretreatment in order to remove chlorine/chloramines. Additional pre and post treatment requirements may vary and are dependent on the quality of the local feed water supply and individual facility requirements.
The EON system is designed to maintain low microbiological levels in the flow pathway through regular heat disinfection and chemical sanitization. Notable components and features of the EON include:
- RO membrane .
- System pump .
- Water quality monitoring system .
- Operating panel and programmable logic controller (OPLC) .
- Heat disinfection and chemical sanitization capability .
- Audible and visual alarms .
- Automatic divert to drain mode upon start-up and anytime product water . TDS is above the quality set-point
- System control via a touch-screen user interface .
- Heat forward cycle intended to heat disinfect connection tubing from the . Portable Reverse Osmosis Water Purification System to the hemodialysis machine.
This document is an FDA 510(k) clearance letter for a medical device, specifically a water purification system. As such, it describes the device itself and its comparison to predicate devices, but it does not contain detailed information about acceptance criteria or a study proving the device meets those criteria in the context of an Artificial Intelligence/Machine Learning (AI/ML) enabled device.
The provided text focuses on:
- Device Name: EON Portable Reverse Osmosis Water Purification System
- Indication for Use: To produce water through reverse osmosis for use with hemodialysis equipment, and optional heat disinfection cycles.
- Regulatory Classification: Class II, Product Code FIP (Water purification system for hemodialysis).
- Comparison to Predicate Devices: EON Portable Reverse Osmosis Water Purification System (K171099) and WRO 300H (K093608). The key difference is the membrane used and minor component changes.
- Non-Clinical Performance Data: Mentions "System and RO Membrane Performance Flow and product water quality verification over range of operating conditions" and "Software Verification."
Therefore, I cannot provide the requested information about acceptance criteria and a study proving the device meets those criteria as it pertains to an AI/ML device. The document describes a physical water purification system, not an AI/ML diagnostic tool.
If this were an AI/ML device, the detailed information requested (sample sizes, expert qualifications, etc.) would typically be found in a separate clinical study report or a more detailed submission summary, not typically in the top-level 510(k) clearance letter itself, which primarily confirms substantial equivalence.
However, if we were to hypothesize what such information would look like for an AI/ML device related to this context (e.g., an AI assessing water purity from sensor data), here's an example of how the requested table and study description might be presented. This is purely illustrative and not based on the provided document.
Hypothetical AI/ML Device for Water Purity Assessment in Hemodialysis
Let's imagine a hypothetical AI/ML device that analyzes sensor data from the EON Portable Reverse Osmosis Water Purification System to predict water purity levels and flag potential issues (e.g., microbial contamination risk, inadequate filtration) to assist hemodialysis technicians.
1. Table of Acceptance Criteria and Reported Device Performance (Hypothetical)
| Acceptance Criteria Category | Specific Metric | Acceptance Criterion | Reported Device Performance (Hypothetical) |
|---|---|---|---|
| Accuracy | Sensitivity (for "Contaminated/Issue" flag) | ≥ 95% | 96.2% (95% CI: 95.5-96.8%) |
| Specificity (for "Contaminated/Issue" flag) | ≥ 90% | 91.5% (95% CI: 90.8-92.2%) | |
| F1-Score | ≥ 0.92 | 0.935 | |
| Precision | Mean Absolute Error (MAE) for TDS prediction | ≤ 5 ppm | 3.8 ppm |
| Standard Deviation of Alerts (False Positives) | ≤ 1 per 1000 operational hours | 0.8 per 1000 operational hours | |
| Robustness | Performance across different feed water types | Sensitivity & Specificity within ±2% of overall | Within ±1.5% across feed water types (Hard, Soft, Chlorinated) |
| Performance under minor sensor drift | Performance metrics maintained with up to 5% sensor drift | Maintained at 4% drift, slight drop at 5% (<1% decrease) | |
| User Experience (with AI) | Reduction in human review time for logs | ≥ 20% reduction | 25% reduction observed in human-in-the-loop study |
| Reduction in missed critical alarms (human+AI) | 100% detection of critical issues observed in test set | 100% of critical issues detected |
Study Proving Device Meets Acceptance Criteria (Hypothetical)
2. Sample Size and Data Provenance for Test Set:
- Sample Size: 10,000 operational hours of sensor data, corresponding to approximately 500 distinct water purification cycles.
- Data Provenance: Retrospective data collected from 15 hemodialysis clinics across the United States (70%), Germany (20%), and Japan (10%) over a 2-year period. Data anonymized and de-identified.
3. Number of Experts and Qualifications for Ground Truth:
- Number of Experts: 5
- Qualifications: Three board-certified Nephrologists with an average of 15 years of experience in hemodialysis and water quality management. Two clinical microbiologists with over 10 years of experience in water quality analysis for medical applications.
4. Adjudication Method for Test Set:
- Method: 3+2 Adjudication. For each data segment requiring ground truth labeling (e.g., "contaminated" or "clean"), three primary experts (2 Nephrologists, 1 Microbiologist) independently reviewed sensor data, lab results (if available), and clinical logs to make an initial determination. If there was a disagreement among these three, the two remaining experts (1 Nephrologist, 1 Microbiologist) were brought in for a consensus discussion until a final label was agreed upon by at least 4 out of 5 experts. If consensus couldn't be reached, the data segment was excluded.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- Was it done? Yes.
- Effect Size of Human Improvement (AI-assisted vs. without AI):
- Study Design: 10 hemodialysis technicians (readers) independently reviewed the 500 water purification cycles from the test set for potential issues.
- Phase 1 (Without AI): Technicians reviewed raw sensor data and log files. The average accuracy for identifying critical water purity issues was 78%.
- Phase 2 (With AI-Assistance): After a washout period, the same technicians reviewed the same cases, this time with the AI system providing alerts and risk scores. The average accuracy increased to 98%.
- Effect Size: The AI assistance led to an average 20% absolute improvement in the accuracy of human readers for identifying critical water purity issues (from 78% to 98%). The relative improvement was approximately 25.6% (20/78). A statistically significant difference (p < 0.001) was observed.
6. Standalone Algorithm Performance:
- Was it done? Yes.
- The standalone algorithm achieved a sensitivity of 96.2% and a specificity of 91.5% for detecting critical water purity issues on the test set, corresponding to the "Reported Device Performance" in the table above.
7. Type of Ground Truth Used:
- Expert Consensus: The primary ground truth was established through expert consensus based on a comprehensive review of sensor data, real-world laboratory water quality reports (e.g., TOC, conductivity, microbial counts if available), and clinical documentation of any related adverse events or interventions. For verification, a subset of the cases with confirmed lab-diagnosed contamination was cross-referenced.
8. Sample Size for Training Set:
- Sample Size: 50,000 operational hours of sensor data, corresponding to approximately 2,500 distinct water purification cycles.
9. How Ground Truth for Training Set was Established:
- Initial ground truth for the training set was established primarily through automated labeling based on predefined thresholds from AAMI water quality standards, combined with routine laboratory analysis results for water quality parameters (e.g., TDS, conductivity, bacterial counts).
- A subset of 10% of the training data was manually reviewed and verified by internal subject matter experts (engineers with hemodialysis system expertise) to correct any noisy or erroneous automated labels, employing a simpler 2-expert review process. This iterative approach helped refine the training data quality.
