The EasyPass Guidewire is used for selective cannulation of the biliary ducts including, but not limited to the common bile duct, cystic duct, and right and left hepatic ducts. The EasyPass guidewire is designed to be used during endoscopic biliary procedures for catheter introduction and exchanges.
The EasyPass Guidewire consists of a Nitinol core wire with a proximal 2-color spiral patterned PTFE jacket and a copolymer distal section. The distal stainless steel spring section of the guidewire provides flexibility and incorporates a hydrophilic coating. The EasyPass Guidewire is a sterile packed, disposable instrument intended for single-patient use only.
This document is a 510(k) premarket notification for the EasyPass Guidewire. As such, it focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study where specific acceptance criteria are defined and statistically proven.
Therefore, the requested information cannot be fully provided in the typical format for a study proving device meets acceptance criteria. However, I can extract the relevant information regarding the performance data provided.
1. Table of Acceptance Criteria and Reported Device Performance
As this is a 510(k) submission, "acceptance criteria" are not explicitly stated in a quantitative manner with pass/fail thresholds for specific performance metrics in the way one might expect for a de novo or PMA submission. Instead, the performance is demonstrated by comparing the device to a predicate and showing it meets "the same performance requirements." The "acceptance criteria" are therefore implicitly that the device performs equivalently to the predicate device in the specified tests.
Acceptance Criteria (Implicit: Performance equivalent to predicate) | Reported Device Performance |
---|---|
Cytotoxicity (per ISO 10993) | Performed; determined to be safe and effective as predicate |
Irritation (per ISO 10993) | Performed; determined to be safe and effective as predicate |
Sensitization (per ISO 10993) | Performed; determined to be safe and effective as predicate |
USP Class VI Testing (for color additives) | Performed; determined to be safe and effective as predicate |
Fracture Test | Performed; determined to be safe and effective as predicate |
Bend Test | Performed; determined to be safe and effective as predicate |
Friction Test | Performed; determined to be safe and effective as predicate |
Scratch Test | Performed; determined to be safe and effective as predicate |
Tensile Test | Performed; determined to be safe and effective as predicate |
Radiographic Image Test | Performed; determined to be safe and effective as predicate |
2. Sample size used for the test set and the data provenance
The document does not specify the exact sample sizes (N) used for each non-clinical performance test. It only states that these tests were conducted. The data provenance is "non-clinical performance data" generated from bench testing and biocompatibility assessments of the proposed EasyPass Guidewire. There is no information regarding the country of origin or whether it's retrospective/prospective as these are not clinical tests.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This document describes non-clinical testing (bench and biocompatibility), not studies involving expert evaluation of clinical data or images.
4. Adjudication method for the test set
Not applicable. No expert adjudication was described for these non-clinical tests.
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 device is a medical guidewire, not an AI-powered diagnostic or assistive tool for human readers. No MRMC study was mentioned.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a medical guidewire, not an algorithm.
7. The type of ground truth used
For the non-clinical performance data, the "ground truth" would be established by the standardized methods and specifications relevant to each test (e.g., ISO 10993 for biocompatibility, material specifications for fracture/bend/tensile tests, etc.). The goal was to demonstrate performance equivalent to the predicate device.
8. The sample size for the training set
Not applicable. This is a medical device, not a machine learning algorithm that requires a training set.
9. How the ground truth for the training set was established
Not applicable. (See #8)

The PolyCatch Retrieval Device is intended for capture and retrieval of excised polyps, foreign bodies, tissue samples and calculi during flexible or rigid endoscopy procedures.
The PolyCatch Retrieval Device is a complete one-piece device for retrieval of polyps and foreign bodies from the gastrointestinal and respiratory tracts and is a disposable instrument intended for single patient use only. The PolyCatch Retrieval Device is used through the working channel of a legally marketed endoscope. The PolyCatch Retrieval Device consists of a handle, outer sheath and a snare wire/loop to which a non-Latex pouch is attached. As the snare wire is advanced from of the outer sheath of the device, it expands to its full circumference thereby deploying the non-Latex pouch. The pouch can then be manipulated by the clinician to engage a polyp or foreign body. After the polyp or foreign body is captured within the pouch the handle is used to draw the snare wire and pouch back against the device sheath. The endoscope along with the PolyCatch is then removed together from the patient to complete the retrieval procedure.
This document is a 510(k) premarket notification for a medical device called the "PolyCatch Retrieval Device." It is a submission to the FDA (Food and Drug Administration) for clearance to market the device. The document states that the device is substantially equivalent to a legally marketed predicate device.
Here's an analysis based on your request, keeping in mind that this type of regulatory submission often focuses on demonstrating equivalence to an existing device rather than presenting extensive de novo clinical trials with AI components.

A table of acceptance criteria and the reported device performance
This document does not specify "acceptance criteria" in terms of performance metrics (like sensitivity, specificity, accuracy) that would typically be associated with an AI-enabled device's diagnostic or predictive capabilities. This is a conventional medical device a "PolyCatch Retrieval Device" which is used for the physical retrieval of polyps, foreign bodies, tissue samples, and calculi. Its "performance" would relate to its mechanical function, biocompatibility, and ability to effectively retrieve objects as intended.
The document states:
"Design verification data and biocompatibility testing has demonstrated that the proposed PolyCatch Retrieval Device is safe and effective."
"Bench performance testing was conducted using a specially designed test fixture intended to simulate actual device use of the PolyCatch Retrieval Device."
"Medi-Globe Corporation has demonstrated that the proposed PolyCatch Retrieval Device is as safe and effective as the predicate device, (Roth Net Retriever, K122462)."Without the full design verification and bench test reports, specific quantitative acceptance criteria and their corresponding results cannot be extracted from this summary. This document operates under the premise of "substantial equivalence" to a predicate device, meaning its performance is considered comparable to the predicate.
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document mentions "Design verification data and biocompatibility testing" and "bench performance testing." These typically involve studies in vitro or on test fixtures, not human patient data in the way an AI study would. Therefore, concepts like sample size of a patient test set, country of origin, retrospective/prospective classification, or human data provenance are not applicable here. The "test set" in this context refers to the materials and conditions used in the bench testing. No specific sample sizes for these tests are provided in this summary.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This is not an AI-enabled device. The "ground truth" for a device like this would be its mechanical integrity, effective capture/retrieval of test objects under simulated conditions, and biocompatibility. This does not require human expert interpretation of images or data to establish a ground truth.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as this is not an AI-enabled diagnostic or predictive device requiring adjudication for ambiguous cases.
-
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 not an AI-enabled device, and no human reader studies are mentioned or implied.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The device is a physical medical instrument, not an algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for a physical retrieval device like this would be defined by engineering specifications and successful mechanical operation under test conditions, as well as satisfactory biocompatibility results. This does not involve expert consensus, pathology, or outcomes data in the way a diagnostic AI would.
-
The sample size for the training set
Not applicable, as this is not an AI-enabled device, and therefore no "training set" in the context of machine learning is used.
-
How the ground truth for the training set was established
Not applicable, for the same reason as point 8.

Instead, the acceptance is based on demonstrating substantial equivalence to predicate devices, meaning the new device has the same intended use and similar technological characteristics, and any differences do not raise new questions of safety or effectiveness.
Acceptance Criteria (Inferred) | Reported Device Performance |
---|---|
Substantial Equivalence to Predicate Devices | "Design verification data has demonstrated that the proposed Medi-Globe SonoTip II 25-gauge Ultrasound Needle System meets the same performance requirements and is as safe and effective as its predicate device. The 25-gauge SonoTip II Needle System is considered to have the same intended diagnostic/therapeutic effect, method of introduction/use, and intended range of descriptive features as the predicate Medi-Globe SonoTip II Ultrasound Needle System (K070129)." This statement confirms the device fulfills the criteria of having comparable performance, safety, and effectiveness to its predicate, based on design verification. |
Intended Use Equivalence | The intended use for the SonoTip II 25-gauge is identical to its predicate: "for ultrasonically guided, fine needle aspiration (FNA) of submucosal and extra-luminal lesions of the gastrointestinal tract (i.e., pancreatic masses, mediastinal masses, peri-pancreatic masses and lymph nodes)." |
Technological Characteristics Equivalence | The device "utilizes endoscopic ultrasound technology which, when used with an ultrasound endoscope, allows the user to ultrasonically guide the biopsy needle to its intended target." This characteristic is consistent with the described predicate devices. |
Material/Design Characteristics (Implicit) | The submission implies that any material or design differences (e.g., the 25-gauge size) do not alter the fundamental safety or effectiveness profile as compared to the predicate. No new questions of safety or effectiveness are raised. |
Study Proving Acceptance Criteria
The study described is a design verification as part of a 510(k) submission for substantial equivalence.
-
Sample size used for the test set and the data provenance:
- The document states "Design verification data has demonstrated..." but does not specify a sample size for any test set nor the data provenance (e.g., country of origin, retrospective/prospective). Design verification in this context likely refers to internal testing (e.g., mechanical testing, materials testing, functional testing) to ensure the device meets its design specifications and performs comparably to the predicate. It is not presented as a clinical study with human subjects.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. This was not a study involving expert assessment of diagnostic accuracy against a ground truth.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable. No clinical test set requiring adjudication is mentioned.
-
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:
- No. This is a medical device for fine needle aspiration, not an AI-assisted diagnostic tool.
-

- No. This is a physical medical device, not an algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not applicable for a clinical ground truth. The "performance requirements" mentioned likely refer to engineering and functional specifications (e.g., needle integrity, fluid aspiration capability, compatibility with ultrasound endoscopes) which would be verified against design specifications, not clinical pathology or outcomes directly in a human cohort during this 510(k) process.
-
The sample size for the training set:
- Not applicable. The submission does not refer to a training set for a machine learning algorithm.
-
How the ground truth for the training set was established:
- Not applicable. (See point 7).
In summary, the K083802 submission for the Medi-Globe SonoTip II 25-gauge Ultrasound Needle System relies on demonstrating substantial equivalence to an existing, legally marketed predicate device (K070129) through design verification data. This approach means that a comprehensive clinical study with detailed performance metrics, ground truth establishment, or human reader assessments was not required or provided in the 510(k) summary, as the device's fundamental safety and effectiveness are established by its similarity to already approved devices.

The Medi-Globe Rota-Cut® Sphincterotome is intended for transendoscopic cannulation of the Biliary system and sphincterotomy of the Papilla of Vater an/or the Sphincter of Oddi.
The proposed Medi-Globe Rota-Cut® Sphincterotome is available in single, double or triple lumen models and allows incremental, rotational orientation of the distal catheter tip and cutting wire. Device models are compatible with either .021 or .035" guide wires and allow simultaneous injection of contrast medium during use.
This is a 510(k) premarket notification for a medical device, the Medi-Globe Rota-Cut® Sphincterotome. This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device rather than conducting a full clinical study with specific acceptance criteria and performance metrics for a novel technology. Therefore, the information requested in your prompt regarding acceptance criteria, performance data, sample sizes, ground truth, and expert involvement is largely not applicable in the context of this specific regulatory document.
Here's an explanation based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
Not Applicable. The 510(k) submission for the Medi-Globe Rota-Cut® Sphincterotome does not present specific quantitative acceptance criteria or detailed device performance metrics in the way a novel AI or diagnostic device would. Instead, it relies on demonstrating substantial equivalence to predicate devices.
The "Performance Data" section states: "Design verification tests have demonstrated that the proposed Rota-Cut® sphincterotomes meet the same performance standards and biocompatibility requirements and is as safe and effective as the currently cleared GIP/Medi-Globe device, (K943629/A)."
This implies that the acceptance criterion for the new device is to perform as well as or equivalently to the predicate device in terms of "performance standards and biocompatibility requirements" and be "as safe and effective." However, no explicit numerical criteria or specific performance values are listed in this document.
2. Sample Size Used for the Test Set and Data Provenance
Not Applicable. No specific "test set" in the context of clinical data for performance evaluation is described. The "design verification tests" are likely referring to bench testing, engineering validation, and biocompatibility testing as per standard medical device development. No human subject data (retrospective or prospective) is mentioned as being used to prove the device's performance against specific metrics through a test set.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
Not Applicable. Ground truth, in the sense of expert consensus on clinical findings, is not established for any test set because there is no clinical test set described in this document to evaluate the device's diagnostic or predictive performance.
4. Adjudication Method
Not Applicable. Since there is no test set with clinical findings requiring ground truth establishment, no adjudication method is described.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. This is a medical device for surgical intervention (sphincterotomy), not an imaging or diagnostic AI device. MRMC studies are typically used for assessing the impact of AI on human readers' diagnostic accuracy. This is not relevant to the Rota-Cut® Sphincterotome.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not Applicable. The Medi-Globe Rota-Cut® Sphincterotome is a physical surgical instrument, not an algorithm. Therefore, "standalone performance" in the context of an algorithm is not applicable.
7. The Type of Ground Truth Used
Not Applicable. As explained above, no clinical "ground truth" for diagnostic or predictive outcomes is mentioned because the performance evaluation is based on substantial equivalence to an existing device, focusing on "performance standards, biocompatibility requirements," and being "as safe and effective." The ground truth for these types of evaluations is often established through well-defined engineering specifications, material standards, and preclinical (e.g., animal or bench) testing protocols.
8. The Sample Size for the Training Set
Not Applicable. Since the device is a physical instrument and not an AI algorithm, there is no "training set" in the context of machine learning.
9. How the Ground Truth for the Training Set Was Established
Not Applicable. As there is no training set for an AI algorithm, this question is not applicable.
In summary, the provided document is a 510(k) summary for a substantial equivalence claim for a physical medical device. It focuses on comparing the new device's technological characteristics, intended use, and safety/effectiveness to previously cleared predicate devices. The detailed performance and clinical study information, including acceptance criteria, sample sizes, and ground truth methodologies, as typically found for novel AI/diagnostic devices, are not present in this type of regulatory submission and are not relevant to demonstrating substantial equivalence for a device like a sphincterotome. The "study" mentioned is "Design verification tests," which are engineering and biocompatibility tests intended to show equivalence to the predicate, not clinical trials with human subjects as implied by many of your questions.

The SonoTip II Ultrasound Needle System is used in conjunction with various legally marketed, FDA registered Ultrasound Endoscopes. The SonoTip II Needle System is used for ultrasonically guided fine needle aspiration (FNA) of submucosal and extra-luminal lesions of the Gastrointestinal tract (i.e., pancreatic masses, mediastinal masses, peri-pancreatic masses and lymph nodes.
The SonoTip 11 Ultrasound Needle System is complete one-piece needle system for Fine Needle Aspiration and is a disposable instrument intended for single 101 I mo Noode Aspirature allowing the length of the outer metal sheath to be adjusted has been incorporated into the SonoTip II needle system. This provides adjusted has been miss to precisely adjust the working length of the instrument to that of the specific ultrasound endoscope scope being used.
The provided text describes the SonoTip II Ultrasound Needle System and its 510(k) clearance. However, it does not contain detailed acceptance criteria, specific performance metrics, sample sizes, expert qualifications, or details about the studies (e.g., standalone, MRMC, or training set specifics) that would allow for a comprehensive breakdown as requested.
The document states:
- "Design verification data has demonstrated that the SonoTip II Ultrasonic Needle System meets design requirements and is as safe and effective as the predicate device."
- "The SonoTip II Needle System is considered to have the same intended diagnostic/therapeutic effect, method of introduction/use, technical characteristics and general range of descriptive features as the predicate Medi-Globe Ultrasound Needle System (K990220)."
This indicates that the clearance was based on substantial equivalence to a predicate device (GIP/Medi-Globe GI Ultrasound Needle System (K990220)) rather than a detailed clinical performance study with specific acceptance criteria and metrics. The "Performance Data" section primarily asserts equivalence.
Therefore, many of the requested fields cannot be filled from the provided text.
Here's a breakdown of what can be extracted and what information is missing:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria | Reported Device Performance |
---|---|
Specific performance metrics (e.g., accuracy, sensitivity, specificity, resolution, penetration depth, or specific force thresholds) | Not specified. The document states: "Design verification data has demonstrated that the SonoTip II Ultrasonic Needle System meets design requirements and is as safe and effective as the predicate device." |
Comparison to predicate for equivalence | The device is "considered to have the same intended diagnostic/therapeutic effect, method of introduction/use, technical characteristics and general range of descriptive features as the predicate Medi-Globe Ultrasound Needle System (K990220)." |
2. Sample size used for the test set and the data provenance
- Sample Size: Not specified.
- Data Provenance: Not specified (e.g., country of origin, retrospective/prospective). The document refers to "Design verification data" but does not detail its source or nature.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not specified.
- Qualifications of Experts: Not specified.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not specified.
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
- No; an MRMC study was not done. This device is a manual medical instrument (a needle system), not an AI-powered diagnostic tool. Therefore, the concept of "human readers improve with AI vs without AI assistance" is not applicable.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not applicable. This is a physical medical device (needle system), not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Not specified. Given the nature of the device (FNA needle), a typical "ground truth" for its performance might involve mechanical testing (e.g., needle sharpness, bend resistance, fluid aspiration efficiency) and biocompatibility, as well as a comparison of histological samples obtained with the device vs. the predicate, but these details are not provided.
8. The sample size for the training set
- Not applicable. This device is a physical instrument, not an AI model, so there is no "training set."
9. How the ground truth for the training set was established
- Not applicable. As above, no training set.
Summary of available information:
The 510(k) clearance for the SonoTip II Ultrasound Needle System was based on demonstrating substantial equivalence to a legally marketed predicate device (Medi-Globe Ultrasound Needle System, K990220). The documentation does not provide specific performance metrics, detailed study designs, sample sizes, or information about expert involvement typically associated with a human-AI performance study. Instead, it relies on "design verification data" to assert that the device meets design requirements and is as safe and effective as the predicate.
