Composite matrix
First Claim
1. A composite matrix comprising a reinforcing textile portion of which both sides, so called first face and second face respectively, are covered over at least 90% of their respective surfaces by at least one first layer comprising at least one resorbable macromolecule, and a collagen content of 50% or more by weight, wherein the first layer of the first face is an antiadhesive layer and the first layer of the second face is a non-porous adhesive layer, the adhesive layer having an adhesive strength sufficient for maintaining said matrix in position on the tissues while enabling said matrix to be removed from the tissues by peeling.
