A composite intraluminal prosthesis which is preferably used as a vascular prothesis includes a layer of ePTFE and a layer of textile material which are secured together by an elastomeric bonding agent. The ePTFE layer includes a porous microstructure defined by nodes interconnected by fibrils. The adhesive bonding agent is preferably applied in solution so that the bonding agent enters the pores of the microstructure of the ePTFE. This helps secure the textile layer to the ePTFE layer.
L'invention concerne une prothèse composite intraluminale, de préférence une prothèse vasculaire, comprenant une couche de ePTFE et une couche de matériau textiles assemblés par un liant élastomère. La couche ePTFE comprend une microstructure définie par des noeuds interconnectés par des fibrilles. Le liant adhésif est appliqué de préférence sous forme de solution ce qui lui permet de pénétrer dans les pores de la microstructure de ePTFE. Ce procédé aide à fixer la couche textile sur la couche de ePTFE.
