Self-Fixating Mesh Improves Hernia Repair Response

An advanced microgrip technology for secure hernia repair provides immediate fixation of the entire mesh surface and even distribution of tension for greater patient comfort.

The Parietex ProGrip Self-Fixating Mesh is composed of a semiresorbable knit of monofilament polyester (PET) and resorbable monofilament polylactic acid (PLA). The resorbable PLA microgrips enable surgeons to position and place the mesh in under a minute, without the need for additional fixation, due to a mushroom-top shaped gripping geometry that provides gripping of the mesh between muscle fibers and connective tissue. The self-gripping feature provides even distribution of tension across the repair area, rather than focusing tension on individual fixation points along the periphery of the mesh that penetrate tissues, potentially entrapping nerves.


The use of the hydrophilic polyester monofilament results in fast and intimate tissue ingrowth, allowing the PLA large pore size (1.1 mm x 1.7 mm) and monofilament fiber composition to work with the body's natural systems to improve tissue response, and reduce foreign material reaction. The PLA mesh has a density of just 74 g/m2 before resorption, and 38 g/m2 after resorption, representing the remaining nonresorbable PET mesh. The Parietex ProGrip Self-Fixating Mesh is a product of Covidien (Dublin, Ireland).

"The mesh is made of a light-weight, hydrophilic polyester which is porous, making it effective for tissue in-growth and also for reducing pain. And by working with the body's natural systems, the mesh cuts down the amount of foreign material left in the body,” said Scott Flora, president of surgical devices at Covidien.
