The development of mesh is described. Current popular prostheses such as polyester, polytetrafluroethylene (PTFE) and polypropylene are reviewed. Chemical, polymer, and textile engineers design prostheses with various characteristics and qualities. These properties are compared according to the American Standard and Testing Methods (ASTM). Absorbable mesh does not remain in the wound long enough for adequate collagen to be deposited. Multifilament mesh can harbor bacteria. Monofilament mesh is the most popular presently in use with the various types of polypropylene having different characteristic advantages.
