Abstract

A prosthesis and a method of making a prosthesis having a needle containment and support structure that minimizes needle point plowing and/or needle scoring and inhibits delamination of the support structure during cannulization of the prosthesis. The prosthesis includes a first tube of expanded polytetrafluoroethylene (ePTFE), a polymer membrane, preferably ePTFE, positioned about the exterior surface of the first tube, and at least one support structure wound along a winding axis about the membrane to form axially spaced-apart ridges on the membrane. The support structure is a bead, filament, or similar structure that is wound about the exterior surface in a helical or spiral pattern to form the spaced apart-ridges. Alternatively, a plurality of spaced support rings can be employed to form the ridges. The ridges are preferably spaced apart a distance effective to direct a needle to a puncture site at an angle that inhibits needle plowing and hole enlarging, approximately less than 1.5 times the outer diameter of the needle. The polymer membrane has a microstructure selected to facilitate bonding of the support structure to the membrane and inhibit delamination of the support structure.
