Prosthetic Materials for Hernia Repair: PTFE (polytetraflouroethylene)
These meshes are widely used in ventral hernia repair. They are usually solid but are available in woven models. They have a lesser degree of inflammation than polypropylene meshes. The mesh can interact with surrounding tissue to form a persistent seroma. PTFE generally should not be placed in a wound with a risk of infection and must be completely removed if a sterile wound subsequently becomes infected. Some types of PTFE with associated characteristics are listed below:
DualMesh, DualMesh Plus – W.L. Gore, the Plus material differs from the plain DualMesh because it is impregnated with antimicrobial silver carbonate and chlorhexidine diacetate to inhibit bacterial colonization.
Bard Dulex Mesh – Davol, two-sided mesh with a smooth side to be placed next to the bowel and a microporous side to be placed against the abdominal wall to promote tissue ingrowth.
MotifMESH – Proxy, has high porosity that facilitates tissue ingrowth, has low tissue inflammation.
Composix – Bard, combination PTFE and polypropylene with the PTFE side placed against the bowel wall, widely used
Composix Kugel Patch – Bard, combination PTFE and Polypropylene, some sizes recalled by the FDA.
