摘要

A vascular graft (20) includes a vessel (32) structure having outer and inne r wall surfaces. The vessel structure has outer and inner transverse dimension s. The vascular graft includes a fold structure (36) which is integral with the vessel structure. The fold structure extends from the outer or inner wall surface of the vessel structure for altering the inner or outer transverse dimension thereof. A method for making the vascular graft facilitates formation of the fold structure.
