PROLENEâ?¢ Polypropylene Mesh is constructed of knitted filaments of extruded polypropylene identical in composition to that used in PROLENEâ?¢ Polypropylene Suture, Nonabsorbable Surgical Sutures, U.S.P. (Ethicon, LLC). The mesh is approximately 0.020 inches thick. This material, when used as a suture, has been reported to be nonreactive and to retain its strength indefinitely in clinical use. PROLENE Mesh is knitted by a process which interlinks each fiber junction and which provides for elasticity in both directions. This construction permits the mesh to be cut into any desired shape or size without unraveling. The fiber junctions are not subject to the same work fatigue exhibited by more rigid metallic meshes. This bi-directional elastic property allows adaption to various stresses encountered in the body.
