PERFORATED REINFORCEMENT PROSTHESIS

摘要

The invention relates to an implantable web (1) for reinforcing and supporting biological tissues, in particular for treating hernias, prolapses and eventrations, said web (1) being formed of a substantially homogenous base structure (2) and having a differentiated deformable structure (3) that comprises at least one so-called rigid area (4) and at least one so-called flexible area (5), wherein said flexible area (5) is characterised in that it comprises one or more material interruptions (10) or one or more material cutouts in order to locally reduce the cohesion of said base structure (2) and to make it more flexible, so that the flexible area (5) has a deformation resistance under stress that is lower than that of the rigid area (4). The invention also relates to implantable prostheses for reinforcing damaged tissues.
