LOW PROFILE VASCULAR GRAFT

摘要

The low profile vascular graft (10) of the present invention includes a tube structure (12) having outer and inner surfaces (14, 16), and a support structure (38) having a chamber structure (40) secured to the outer or inner surface. The support structure includes a core structure (62) contained within the chamber structure. The core structure is transformable from a conformance condition to a reinforcement condition. When the core structure is in the conformance condition, it provides insubstantial resistance to deformation of the tube structure. When the core structure is in the reinforcement condition, it provides substantial resistance to deformation of the tube structure.
