Abstract:
A method for making a vascular graft, comprising the steps of:radially expanding at least a longitudinal section of a tubular graft member formed of microporous expanded polytetrafluoroethylene in a mold cavity to an expanded diameter which is greater than remaining radially unexpanded longitudinal sections of the expanded polytetrafluoroethylene tubular graft member, where a tapered longitudinal section is interdisposed between the radially expanded and radially unexpanded longitudinal sections of the expanded polytetrafluoroethylene tubular graft member;removing the expanded polytetrafluoroethylene tubular graft member from the mold cavity; andtrimming the expanded polytetrafluoroethylene tubular graft member to form a vascular graft having at least one flanged section or a collar section projecting from a distal end thereof.
