LTM-Laparoscopic Surgical Mesh 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. Indications for use include the repair of hernias and/or body wall defects which require the use of reinforcing or bridging material to obtain the desired surgical outcome during open or laparoscopic procedures.

LTM-Laparoscopic Surgical Mesh is intended for single patient one-time use only.

The LTM-Laparoscopic Surgical Mesh is a surgical mesh that is derived from porcine dermal tissue. The LTM-Laparoscopic Surgical Mesh device consists of a terminally sterilized sheet of the processed porcine dermal matrix provided in prescribed geometric configurations and sizes ranging from 10 cm x 16 cm to 20 cm x 20 cm, with future sizes planned ranging from 2 cm x 2 cm to 20 cm x 30 cm. It will be packaged in double pouch configuration.

The document describes the LTM-Laparoscopic Surgical Mesh, a device intended for surgical repair of hernias and body wall defects. The submission focuses on demonstrating substantial equivalence to a predicate device, LTM Surgical Mesh (K070560), and discusses its performance relative to established specifications.

Here's an analysis of the provided information, structured according to your request:

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the numerical sample size for the test set or the data provenance (e.g., country of origin, retrospective/prospective). It refers to "extensive biocompatibility testing, animal testing, viral inactivation testing, and biomechanical testing" of the predicate device (K070560). For the LTM-Laparoscopic Surgical Mesh itself, it states that it "went through the same biomechanical testing after laparoscopic handling (Attachment 1)."

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the document. The study primarily relies on physical and manufacturing consistency with a previously cleared device and biomechanical testing, rather than expert evaluation of the device in a clinical or diagnostic context.

4. Adjudication Method for the Test Set

This information is not applicable/provided as the study focuses on physical and mechanical properties rather than subjective assessments requiring 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

An MRMC study was not done. This device is a surgical mesh, not an AI-powered diagnostic tool, so such a study would not be relevant.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

A standalone performance study of an algorithm was not done. This is a physical surgical device, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is established through biomechanical specifications and performance data derived from the predicate device (LTM Surgical Mesh K070560) and further confirmed through specific tests on the LTM-Laparoscopic Surgical Mesh after simulated laparoscopic handling. This includes:

• Tensile Strength
• Tear Resistance
• Suture Pull-out Strength
• Burst Strength
• Biocompatibility data (from predicate)
• Viral inactivation data (from predicate)

8. The Sample Size for the Training Set

The concept of a "training set" is not applicable to this submission, as it concerns a physical surgical device, not a machine learning algorithm.

9. How the Ground Truth for the Training Set was Established

This information is not applicable as there is no training set for a machine learning algorithm.
