Endoform Dental Membrane is specifically intended for use in extraction sockets and soft tissue grafting. The device contains and prevents migration of guided bone regeneration graft material and prevents loss of alveolar height and ridge following tooth extraction. The device is provided sterile and intended for one-time use.

Endoform Dental Membrane is an ovine derived bioabsorbable extracellular matrix intended for application in dental and periodontal procedures. The device is composed of non-cross linked and non-reconstituted collagen. The device is supplied sterile in a variety of sizes and thicknesses which may be trimmed by a licensed dentist or oral surgeon to meet individual patient needs.

The provided text describes the non-clinical testing performed on the Endoform Dental Membrane to demonstrate its safety and performance. However, it does not include information about acceptance criteria for all the tests, nor does it detail a study that defines "device performance" in terms of clinical or comparative effectiveness against specific criteria in the way you've outlined.

Based on the available text, here's a breakdown of the information that is present, and what is not:

1. Table of Acceptance Criteria and Reported Device Performance

Note: The document details numerous non-clinical tests. For many, it states that the device "met the pre-defined specification" or "meets the specification," but it often does not explicitly list the numerical acceptance criteria in this summary. The table below compiles the criteria where they are explicitly mentioned.

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

The document describes several non-clinical tests but does not explicitly state the specific numerical sample sizes for each test set. It mentions "All EDM devices" or "all samples" in some contexts.

For the Animal Performance Testing:

• Sample Size (Test Set): Not explicitly stated how many animals were used, but it was an ovine (sheep) defect model study using "selected timepoints (week 4, 8 and 16)".
• Data Provenance: Prospective animal study conducted in an ovine (sheep) defect model. The country of origin is not specified, but the applicant's address is New Zealand.

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

This information is not provided in the document. The non-clinical tests described rely on validated laboratory methods and specifications, which are based on scientific standards rather than expert consensus on a test set in the way clinical diagnostic devices might.

For the animal study, the assessment criteria (resorption, cellular infiltration, inflammatory response, retention of bone grafting material, hard tissue infill) would likely be evaluated by veterinarians or pathologists, but the number and qualifications of these experts are not mentioned.

4. Adjudication Method for the Test Set

This information is not provided as the document focuses on laboratory and animal study results rather than human-read test sets.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No. A MRMC comparative effectiveness study was not performed or described. The document explicitly states: "Clinical data was not required to demonstrate substantial equivalence."

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

Not applicable. This device is a bioabsorbable extracellular matrix (Endoform Dental Membrane), not an AI algorithm. Therefore, "standalone algorithm" performance is not relevant.

7. Type of Ground Truth Used

The "ground truth" for the various tests conducted for the Endoform Dental Membrane is based on:

• Validated Test Methods: For biochemical content (collagen, GAG, DNA), physical properties (moisture, DSC, permeability, suture retention, modulus, thickness), residual substances (Tx-100, EDTA, PAA), bioburden, endotoxin, and shelf-life. These are quantitative measurements against predefined specifications.
• Standards Compliance: For biocompatibility (ISO 10993 series), sterilization (ISO 11135), and packaging (ASTM standards).
• Histopathological and Macroscopic Assessment: For the animal performance study, evaluating resorption, cellular infiltration, inflammatory response, and bone graft retention based on examinations at specific time points. This likely involves expert evaluation of tissue samples, but it's not "expert consensus" on a diagnostic task, rather assessment of biological outcomes compared to a reference device.
• "Critically sized" defects: The animal study also demonstrated that untreated controls did not completely regenerate bone, indicating the defects were appropriately sized for evaluating the device's performance.

8. Sample Size for the Training Set

Not applicable. This device is a physical medical device, not an AI algorithm. Therefore, there is no "training set."

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

Not applicable. As above, there is no training set for this type of device.

Ask a specific question about this device

Endoform® Reconstructive Template is intended for use as a surgical mesh to reinforce and/ or repair soft tissue where weakness exists. Indications for use include the repair of hernias and/or abdominal wall defects that require the use of reinforcing or bridging material to obtain the desired surgical outcome.

Endoform Reconstructive Template - Non-Absorbable is a surgical mesh manufactured by layering sheets of ovine forestomach matrix (OFM) to create 1- through 10- ply embroidered devices for soft tissue reconstruction. The device design includes thicknesses from 1- through 10- ply to give a range of strengths as required for a particular implant procedure. The construction of Endoform™ Reconstructive Template - Non-Absorbable devices includes lyophilization of single sheets of OFM followed by embroidery with polypropylene. Devices are terminally sterilized by ethylene oxide (EO) sterilization.

This document is an FDA 510(k) premarket notification decision letter for a surgical mesh device, Endoform® Reconstructive Template - Non-Absorbable. It does not describe an AI medical device or a study involving AI. Therefore, it is impossible to answer the questions about acceptance criteria and study proving an AI device meets those criteria based on the provided text.

The document discusses the substantial equivalence of the surgical mesh to a predicate device based on:

• Biocompatibility Data: Additional cytotoxicity testing, toxicological assessment, and viral inactivation assessment were performed.
• Performance Data: Biomechanical testing (uniaxial tensile strength, ball burst strength, suture retention strength) and an in-vivo study in a soft tissue reinforcement model.
• Clinical Data: No clinical data was submitted.

The provided text pertains to a physical medical device (surgical mesh) and its substantial equivalence determination, not an AI/ML medical device. Therefore, the questions about acceptance criteria for an AI device, sample sizes for AI test/training sets, experts for ground truth, adjudication methods, MRMC studies, standalone performance, and ground truth establishment for AI models are not applicable to the content of this document.
