Support structure/membrane composite medical device

Abstract

Abstract The present invention relates to a support structure/membrane composite device (16) which includes a support structure, such as a radially expandable stent (10), a porous non-textile polymeric membrane (14) adjacent to said stent and a thermoplastic anchor means (18) attaching said stent to said porous non-textile polymeric membrane. The porous non-textile polymeric membrane is preferably made from expandable fluoropolymer materials. The anchoring means is a thermoplastic material which is dissolvable at the interface between the support structure and membrane by a suitable solvent which wets the membrane surface and deposits the thermoplastic material within the pores of the membrane. Methods of preparing the device are also disclosed.
