Abstract

Surgical mesh is a porous layer that is produced from polymeric monofilaments such as polypropylene using a warp knitting method. Surgical mesh is widely used for hernia repair and pelvic organ prolapse. A hernia is a protrusion of the whole or part of a viscus from its normal position through an opening in the wall of its containing cavity. For hernia repair, the defect should be closed with suture and/or surgical mesh by a conventional/laparoscopy surgical operation. Surgical meshes can be made from stable (non-resorbable) polymers, resorbable polymers, natural polymers, or their composites. An ideal prosthesis should be strong, flexible, non-sensitizing and non-reacting. The type of surgical mesh, pore size, porosity and area density of surgical mesh have special effects on the properties of surgical mesh and its performance after a surgical operation. Among the mechanical properties of meshes, tensile strength, bursting strength, tearing resistance and suture retention strength are important and affect the functional properties of a surgical mesh after in vivo transplantation. This is a short review of surgical meshes and their required properties.
