Device Description

AI/ML Overview

The provided text is a 510(k) summary for a medical device called "Peri-Strips Staple Line Reinforcement." It describes the device, its intended use, and its substantial equivalence to a predicate device. However, it does not include acceptance criteria, details of a study that proves the device meets specific performance criteria, or any of the detailed information requested in points 2-9 of your prompt (sample sizes, ground truth establishment, expert qualifications, adjudication methods, MRMC studies, standalone performance, or training set details).

Medical devices like the Peri-Strips Staple Line Reinforcement, when cleared via the 510(k) pathway, typically demonstrate substantial equivalence to a legally marketed predicate device. This process often relies on showing that the new device has the same technological characteristics and similar indications for use as the predicate, and does not raise new questions of safety and efficacy. This usually involves engineering testing (e.g., tensile strength, burst pressure) and biocompatibility testing, rather than clinical efficacy studies with the detailed metrics you've asked for that are more common for AI/ML-based devices.

Therefore, I cannot populate the table or answer the specific questions about acceptance criteria, study details, expert involvement, or AI/ML performance because the provided document does not contain this information.

Based on the provided text, the device is cleared on the basis of substantial equivalence to a predicate device, and the submission does not detail efficacy studies with specific performance metrics or the involvement of AI/ML.

Here is what can be inferred or explicitly stated from the document regarding comparative testing, but it does not fit the format of your requested table for acceptance criteria and device performance as those specific values are not provided.


1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Not Explicitly Stated for Performance)Reported Device Performance (Not Explicitly Stated as Numerical Metrics)
Substantial equivalence to predicate device"Peri-Strips® Staple Line Reinforcement is substantially equivalent to the predicate device, having the same technological characteristics."
-"Peri-Strips® Staple Line Reinforcement is substantially equivalent to the predicate device in term of testing and indications for use."

No specific numerical performance criteria (e.g., accuracy, sensitivity, specificity, or device-specific mechanical performance thresholds) or corresponding reported values are provided in the document. The basis for clearance is "substantial equivalence" to a predicate device, implying that its performance is presumed to be similar without needing to meet new, explicit, quantitative acceptance criteria for efficacy or exact performance metrics publicly disclosed in this summary. Engineering and biocompatibility testing would have been submitted, but the detailed results are not in this public summary.


Regarding the other questions:

  1. Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • Not provided. The document refers to "testing" as part of establishing substantial equivalence, but gives no details about sample sizes, data provenance, or study design (retrospective/prospective). This often indicates that the testing was primarily mechanical, chemical, or biocompatibility-related, rather than clinical efficacy studies with patient data.
  2. 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)

    • Not applicable / Not provided. The device is a "Surgical Mesh" (an implantable patch/reinforcement), not an imaging or diagnostic device that typically relies on expert interpretation to establish ground truth for performance evaluation in the way an AI/ML diagnostic tool would. Expert review would be part of the design and risk assessment, but not typically in establishing "ground truth" for a performance test set as envisioned for AI.
  3. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not applicable / Not provided. Since there's no mention of a test set requiring expert ground truth or interpretation, an adjudication method isn't relevant to the information provided.
  4. 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. The device is "Peri-Strips Staple Line Reinforcement," a physical surgical implant, not an AI/ML-based diagnostic or assistive device that would involve human readers or AI assistance.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    • Not applicable. This is a physical surgical device, not an algorithm.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    • Not applicable / Not provided. For a physical device like this, "ground truth" in the AI/ML context doesn't apply. Performance would be assessed through established physical/mechanical testing standards (e.g., burst strength, suture retention), biocompatibility, and potentially animal or limited human clinical data to assess safety and gross functional equivalence. These details are not in the summary.
  7. The sample size for the training set

    • Not applicable. This is not an AI/ML device, so there is no "training set."
  8. How the ground truth for the training set was established

    • Not applicable. This is not an AI/ML device, so there is no "training set" or associated ground truth establishment.

Dear Ms. Mallery:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration. Iisting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
