Intended Use

DynaMesh®-VENTRAL serves to support the tissue and stabilize the fascial structures of the abdominal wall. DynaMesh®-VENTRAL is indicated for repairing hernias in all current extraperitoneal surgical thecniques.

Device Description

The FEG Textiltechnik Forschungs- und Entwicklungsgesellschaft mbH DynaMesh®-VENTRAL is a textile structure knitted from non absorbable, bio-stable Polyvinylidene fluoride (PVDF) monofilament fiber. The grade of Polyvinylidene Fluoride (PVDF) used is SOLEF®1008 of Solvay Solexis. The knitted mesh structure consists of uncoloured PVDF Monofilaments with a zig-zag pattern of green-coloured PVDF Monofilaments as visual aid to the clinician that facilitates correct mesh positioning; the mesh is correctly positioned when the ziqzag-stripes are in the craniocaudal direction. The used green dye is Phtalocyanine green, CAS1328-53-6,PG7 of BASF. DvnaMesh®-VENTRAL is supplied as a sterile, flat sheet of material without any coatings. The FEG Textiltechnik's DynaMesh®-VENTRAL will be packed in a cardboard box. Within the cardboard box the device will be double-packed in two paper-poly pouches suitable for Ethylene Oxide sterilization; the labeled outer pouch contains the inner pouch and four adhesive labels for use on patient records.

AI/ML Overview

The provided text is a 510(k) Summary for the DynaMesh®-VENTRAL surgical mesh, which is a medical device for repairing hernias. This document is a premarket notification to the FDA to demonstrate that the device is substantially equivalent to a legally marketed predicate device. As such, it does not contain the detailed study information typically found in an FDA PMA (Premarket Approval) application or a clinical trial report.

Here's a breakdown of the requested information based on the provided text, with explanations for what is not present:


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

The document does not explicitly state "acceptance criteria" with numerical thresholds against which the DynaMesh®-VENTRAL was evaluated. Instead, it lists "Laboratory Bench Tests" that were conducted to "demonstrate performance to an accepted norm and/or substantial equivalence to the predicate products." The performance details for each test (e.g., specific burst strength values, tensile strength values) are not reported in this summary.

Test TypeAcceptance Criteria (Not explicitly stated in document)Reported Device Performance (Not detailed in document)
Burst Strength TestTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)
Tensile StrengthTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)
Maximum elongationTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)
Suture Pullout Strength TestTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)
Tear Resistance TestingTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)
Porosity TestTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)
Mesh stiffnessTo meet accepted norms and/or be substantially equivalent to predicatePerformance demonstrated (details not provided)

2. Sample size used for the test set and the data provenance

The document mentions "various Laboratory Bench Tests" but does not specify the sample sizes used for these tests. Data provenance (country of origin of the data, retrospective or prospective) is also not mentioned for these bench tests. Given they are bench tests on the device materials, "country of origin of the data" would likely refer to the testing facility, which is not specified.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This information is not applicable or not provided in this type of submission. Bench tests typically involve laboratory technicians or engineers performing standardized tests, not medical experts establishing ground truth in a clinical context.

4. Adjudication method for the test set

This information is not applicable or not provided. Adjudication methods are typically used in clinical studies involving human interpretation or outcomes, not for material property bench tests.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done

No, an MRMC comparative effectiveness study was not done or mentioned. This document describes a 510(k) submission based on substantial equivalence to a predicate device, primarily supported by bench testing of material properties, not clinical comparative effectiveness studies involving human readers.

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

Not applicable. The DynaMesh®-VENTRAL is a physical surgical mesh, not a software algorithm or AI device.

7. The type of ground truth used

For the bench tests, the "ground truth" would be the physical properties and performance of the device as measured by standardized laboratory methods. This isn't "expert consensus," "pathology," or "outcomes data" in the clinical sense. These tests aim to objectively measure the material characteristics of the mesh. The comparison is made against "accepted norms" and the performance of the predicate device.

8. The sample size for the training set

Not applicable. This is a physical medical device, not an AI/ML algorithm that requires a training set.

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

Not applicable. As mentioned above, this is not an AI/ML algorithm.

Dear Mr. Armstrong:

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.
