This document is a 510(k) clearance letter for a medical device called the "Aero Jet Ventilation Catheter." 510(k) clearances are for demonstrating substantial equivalence to a predicate device, not for proving new claims of safety and effectiveness through clinical trials with strict acceptance criteria based on new performance metrics.
Therefore, the provided document does not contain the information requested regarding acceptance criteria and a study that proves the device meets those criteria in the way described in the prompt (e.g., related to AI/algorithm performance, MRMC studies, specific effect sizes, ground truth establishment, or sample sizes for test/training sets in the context of diagnostic/AI performance).
The "performance testing summary" in the document refers to standard engineering and biocompatibility tests to show the device functions as intended and is safe, similar to the predicate device. It is not a study to establish performance against specific clinical or diagnostic metrics with human readers or AI in the way implied by the prompt's detailed questions.
Based on the provided text, I cannot complete the table or answer the questions as they pertain to a study proving device performance against acceptance criteria in a clinical/diagnostic context (like an AI study). The 510(k) process for this device relies on demonstrating equivalence to an existing device, primarily through engineering and bench testing, not through comparative clinical studies as you've outlined for diagnostic/AI devices.
Here's what I can extract from the document regarding "acceptance criteria" in the context of a 510(k) submission for this type of medical device:
The acceptance criteria for a 510(k) submission for a device like the Aero Jet Ventilation Catheter are implicitly tied to demonstrating substantial equivalence to a predicate device. This typically involves showing:
- Same Indications for Use: The new device is intended for the same uses as the predicate.
- Same Technological Characteristics: The new device has similar design, materials, and operating principles.
- Differences Do Not Raise New Questions of Safety/Effectiveness: If there are differences, testing must show they do not negatively impact safety or effectiveness.
The "studies" performed are primarily non-clinical functional and performance testing alongside biocompatibility testing. These tests are designed to show that the device performs its intended mechanical functions reliably and safely, and interacts biocompatibly with the body, similar to the predicate.
Therefore, the table and answers below reflect the type of "acceptance criteria" and "proof" found in this specific 510(k) document, which differs significantly from criteria for AI/diagnostic performance studies.
Acceptance Criteria & Device Performance (Based on K243579)
Since this is a 510(k) for a physical medical catheter, the "acceptance criteria" are not focused on diagnostic accuracy or AI performance, but rather on physical and functional characteristics to demonstrate substantial equivalence to a predicate device. The "performance" is implicitly tied to meeting these engineering and biocompatibility standards.
Table of Acceptance Criteria and the Reported Device Performance
Acceptance Criteria Category (Implied by 510(k)) | Specific Criteria / Test Type | Reported Device Performance (Summary from Submission) |

This document outlines the acceptance criteria and reports on the study that demonstrates the Puritan PurSafe Plus Collection and Transport System meets these criteria, based on the provided FDA 510(k) clearance letter.
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria Category | Specific Criteria | Puritan PurSafe Plus Performance |
---|---|---|
Limit of Detection (LOD) | The device should not adversely affect the stated detection limits of the downstream molecular diagnostic device for SARS-CoV-2 viral RNA. Specifically, it should achieve positive detection at an estimated concentration of 64 genome copies/mL when used with the Cepheid GeneXpert® IV system (Xpert Xpress Cov-2/Flu/RSV). | Met. The study indicated positive detection of viral RNA at an estimated concentration of 64 genome copies/mL using the Cepheid GeneXpert® IV system. Quantitative droplet digital PCR showed no significant loss of detection for samples stored in Nasal + PurSafe Plus compared to just nasal matrix alone. No significant differences in SARS-CoV-2 RNA positive detection were observed among PurSafe lots and the predicate Zymo product. Additionally, 20 replicates at the LOD concentration (64 genome copies/mL) over six days yielded positive detection for all replicates, with Ct values within 2 units. |
SARS-CoV-2 RNA Stability | The device should preserve SARS-CoV-2 RNA for up to 28 days at temperatures of 4°C and 30°C, demonstrating no significant loss in the ability to positively detect SARS-CoV-2 using the Cepheid GeneXpert® IV system. | Met. For all three Puritan lots and the Zymo lot, samples stored at 4°C and 30°C for up to 28 days showed no significant loss in the ability to positively detect SARS-CoV-2. Mean Ct values for all samples across all time points and temperatures were less than 3 Ct units from baseline. All Puritan lots were found to be equivalent to the Zymo product in preservation of SARS-CoV-2 RNA. |
Viral Inactivation | The device's buffer should be able to inactivate SARS-CoV-2 virus after exposure. | Met. SARS-CoV-2 virus was inactivated after exposure to three different lots of Puritan PurSafe Plus buffer (at 1:0 dilution) after a minimum of 1 minute of exposure. Cytotoxicity was observed at a 1/10 dilution of the buffer but not at 1/60, informing subsequent inactivation study dilutions. |
2. Sample Size and Data Provenance
- Test Set Sample Size:
- LOD Study: N=24 for the initial assessment (6 concentrations x 2 replicates x 2 lots). N=20 for the confirmatory LOD (20 replicates at 64 genome copies/mL).
- Stability Study: N=72 (4 lots x 5 time points x 2 incubation temperatures x 2 replicates).
- Data Provenance: The data was generated using heat-inactivated SARS-CoV-2 virus (BEI Resources; ATCC # VR-1986HK) spiked into clinically negative human nasal matrix (Lee Biosolutions, Maryland Heights, MO). This suggests retrospective analysis on a prepared sample matrix rather than prospective patient samples. The country of origin of the data is not explicitly stated, but the vendors for the virus and nasal matrix are US-based.
3. Number of Experts and Qualifications for Ground Truth
- The document does not mention the use of human experts to establish ground truth for the performance studies.
- The ground truth for the studies was based on the known concentration of spiked heat-inactivated SARS-CoV-2 virus and the analytical performance of the Cepheid GeneXpert® IV system and droplet digital PCR.
4. Adjudication Method for the Test Set
- No adjudication method is described. The studies rely on quantitative measurements of viral RNA detection using laboratory instruments (Cepheid GeneXpert® IV and ddPCR) and direct observation of viral inactivation.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No MRMC comparative effectiveness study was done. This device is a collection and transport system, not an interpretive diagnostic AI algorithm that would typically involve human readers. Therefore, the effect size of human readers improving with or without AI assistance is not applicable.
6. Standalone Algorithm Performance Study
- A standalone performance study was done. The studies described (LOD, Stability, Inactivation) assess the performance of the Puritan PurSafe Plus Collection and Transport System (the "device" or "algorithm" in this context) directly, without human interpretation or intervention in the diagnostic process beyond laboratory procedures. The system's ability to preserve and inactivate the virus, and not interfere with downstream molecular detection, is evaluated independently.
7. Type of Ground Truth Used
- The type of ground truth used was analytical ground truth and virological ground truth.
- Analytical Ground Truth: For the LOD and Stability studies, known concentrations of heat-inactivated SARS-CoV-2 (quantified in genome copies/mL) were spiked into confirmed clinically negative nasal matrix. The expected outcome was the detection of this known concentration by the downstream molecular diagnostic device.
- Virological Ground Truth: For the Inactivation study, the presence or absence of viable SARS-CoV-2 virus after exposure to the buffer was the ground truth, assessed by exposing VeroE6 cells to the treated virus.
8. Sample Size for the Training Set
- The document does not specify a training set sample size. This is because the device is a physical collection and transport system, not an AI or machine learning model that typically requires a separate training set. The performance studies described are for validation, not model training.
9. How Ground Truth for the Training Set Was Established
- As there is no explicit training set for an AI/ML model, the concept of establishing ground truth for a training set is not applicable to this device. The ground truth described in point 7 is for the validation of the device's functional performance.

The provided document is a 510(k) premarket notification for the Zavation VariSync Plate System & VariSync Spacer System. This type of document focuses on demonstrating substantial equivalence to a predicate device, rather than providing detailed acceptance criteria and performance study results like those expected for novel device approval or AI-based software.
Therefore, many of the requested details, such as specific acceptance criteria in numerical terms, sample sizes for test sets (as these are not clinical studies for efficacy in the same way), number of experts for ground truth, adjudication methods, multi-reader multi-case studies, standalone performance details, training set information, or how ground truth was established for training sets, are not applicable to this type of submission.
Instead, the document highlights mechanical testing to show that the new device performs similarly to existing, legally marketed predicate devices.
Here's an breakdown of the information that is available in the provided text:
1. A table of acceptance criteria and the reported device performance:
The document does not present a table of specific numerical acceptance criteria (e.g., "Accuracy > 90%"). Instead, the acceptance is based on demonstrating substantial equivalence to predicate devices through mechanical testing. The reported performance is that the "mechanical test results demonstrated that the Zavation VariSync Plate System and The VariSync Spacer System is substantially equivalent to the predicate devices."
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Performance similar to predicate devices in mechanical tests | Demonstrated substantial equivalence to predicate devices via mechanical test results |
2. Sample size used for the test set and the data provenance:
- Sample Size: Not explicitly stated as a "test set" in the context of clinical or AI studies. For mechanical testing, the "sample size" would refer to the number of devices or constructs tested. This detail is not provided in the summary.
- Data Provenance: The mechanical testing was performed in accordance with recognized ASTM standards (F2077, F2267, F1717). The location or specific laboratory where these tests were conducted is not mentioned. This is not a human data provenance (e.g., country of origin, retrospective/prospective) but rather a lab-based, engineering testing provenance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. Ground truth in this context refers to the physical properties and performance characteristics determined by standardized mechanical tests, not expert medical opinion on a dataset.
4. Adjudication method for the test set:
- Not applicable. The "ground truth" for mechanical testing is derived from the results of the standardized tests themselves, not through expert adjudication.
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:
- Not applicable. This is a medical device for spinal fusion, not an AI software device that assists human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an algorithm or AI device.
7. The type of ground truth used:
- Mechanical Performance Data: The "ground truth" is established by the results of standardized mechanical tests (ASTM F2077, ASTM F2267, ASTM F1717) designed to assess the strength, stability, and other physical properties of intervertebral body fusion devices and spinal implant constructs.
8. The sample size for the training set:
- Not applicable. There is no "training set" in the context of AI or machine learning for this type of device submission. The device's design is based on engineering principles and similarity to predicate devices.
9. How the ground truth for the training set was established:
- Not applicable. As there's no training set, there's no ground truth for it.
In summary:
The provided document describes a traditional 510(k) submission for a physical medical device (spinal implantation system). The "study" mentioned is mechanical testing performed according to ASTM standards. The purpose of this testing is to demonstrate that the various components of the Zavation VariSync Plate System and VariSync Spacer System perform mechanically in a way that is substantially equivalent to legally marketed predicate devices, thereby establishing their safety and effectiveness for their intended use. This is a crucial distinction from AI/Software as a Medical Device (SaMD) clearances which would typically involve the types of detailed data analysis and ground truth assessment you've inquired about.
