摘要

A method of forming a composite textile and ePTFE implantable device includesthe steps of providing an ePTFE layer; providing a textile layer; applying acoating of an elastomeric bonding agent to one of the surfaces of the ePTFElayer or the textile layer; providing a hollow member having an open end andan opposed closed end defining a fluid passageway therebetween and having awall portion with at least one hole extending therethrough, the hole being influid communication with the fluid passageway; concentrically placing theePTFE layer and the textile layer onto the hollow member and over the at leastone hole of the hollow member, thereby defining a composite assembly; placingthe hollow member with the composite assembly within a pressure chamber;applying a pressure differential so that the pressure within the chamber isgreater than a pressure within the fluid passageway of the hollow member; andapplying heat to the bonding agent to adhesively bond the textile layer andthe ePTFE layer to provide a laminated composite assembly.
