Abstract

L'implant se présente comme une structure multicouches microporeuse formée par l'application de plusieurs films de polytétrafluoréthylène microporeux orienté (films PTFE) qui différent en termes d'orientation des fibres de chaque couche du PTFE par rapport à la couche adjacente. Les films PTFE sont des couches orientées sur deux axes, l'orientation des fibres de chaque couche du PTFE étant perpendiculaire à celle des fibres de chaque couche adjacente. L'implant est formé par la superposition de 2 à 96 couches de films orientés sur deux axes et peut comprendre au moins une couche non poreuse en copolymère de tétrafluoréthylène avec héxafluoropropylène ou du caoutchouc fluoré ou de film PTFE en flocons.
