Intended Use

HPTM is intended for use as a soft tissue patch to reinforce soft tissue where weakness exists and for the surgical repair of damaged or ruptured soft tissue membranes which require the use of reinforcing material to obtain the desired surgical outcome. The implant is intended for reinforcement of soft tissue in plastic and reconstructive surgery.

HPTM is intended for single patient, one-time use only.

Device Description

HP Tissue Matrix is a surgical mesh that is derived from porcine dermis and is processed and preserved in a phosphate buffered aqueous solution containing matrix stabilizers. This device is designed to perform as a surgical mesh for soft tissue repair. The device consists of a terminally sterilized sheet of the processed porcine dermal matrix provided in prescribed geometric configurations and thicknesses and is packaged in a double pouch configuration. The device is considered a single use device which is to be used in a healthcare facility or hospital. It is sterilized via Gamma irradiation.

AI/ML Overview

The provided text describes the 510(k) premarket notification for the HPTM surgical mesh. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study proving performance against defined acceptance criteria in a clinical context with human readers and ground truth.

Therefore, many of the requested sections about acceptance criteria, clinical study details, expert involvement, and reader performance cannot be extracted directly from this document. The document primarily details bench testing for material characteristics.

Here's an analysis of what can be extracted and what cannot:

1. A table of acceptance criteria and the reported device performance

The document provides a list of bench tests performed but does not explicitly state acceptance criteria or the specific numerical results of the device's performance for each test. It only states that "The results of the tests performed demonstrated that the modifications did not affect safety and efficacy of the device or raise any new questions of safety or efficacy."

Test or EvaluationAcceptance CriteriaReported Device Performance
Mesh ThicknessNot specified in document"did not affect safety and efficacy"
Tensile StrengthNot specified in document"did not affect safety and efficacy"
Suture Pullout StrengthNot specified in document"did not affect safety and efficacy"
Tear StrengthNot specified in document (refers to ASTM D5735-95)"did not affect safety and efficacy"
Burst StrengthNot specified in document (refers to ASTM D6797-07(2011))"did not affect safety and efficacy"
Device StiffnessNot specified in document"did not affect safety and efficacy"
BiocompatibilityNot specified in document (refers to ISO 10993 -1, ISO 14971:2007)"did not affect safety and efficacy"
DrapeNot specified in document"did not affect safety and efficacy"

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

  • Sample Size: Not specified for the bench tests.
  • Data Provenance: Not applicable as this is bench testing on materials, not human data. There is no mention of country of origin.

3. 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. This document describes bench testing of a physical medical device, not an AI or diagnostic device requiring expert interpretation for ground truth.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. There is no human interpretation or adjudication involved in the described bench testing.

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. The document explicitly states: "No clinical testing was included in this submission." This is a 510(k) submission for a surgical mesh, not a diagnostic AI device, so such a study would not be expected or relevant here.

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. The "device" is a physical surgical mesh.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not applicable. For the bench tests, the "ground truth" would be the measured physical properties of the material, compared to established material standards (like ASTM or ISO) or the predicate device.

8. The sample size for the training set

Not applicable. This is not an AI or algorithm device requiring a training set.

9. How the ground truth for the training set was established

Not applicable.

Dear Ms. Leiwant:

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, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
