摘要
A structurally supported graft (10) having a support structure (26) with strain relief sections (30) contained with an internal surface, an external surface, or a wall thickness of a tubular graft member (12). The structurally supported graft (10) may include a beading element (24) which is coextruded with the support structure (26) having strain relief sections (30) and spiraled about the tubular graft (10). The support structure (26) includes differing types of strain relief sections (30) which are capable of allowing for the longitudinal and radial expansion of the structurally supported graft, respectively. The strain relief sections may also include unconnected ends which form outwardly protruding barbs (62) upon expansion of the structurally supported graft for anchoring the graft within a blood vessel or body lumen. The method for making the structurally supported graft includes selecting or preparing a support structure with strain relief sections, co-extruding the structural support with a beading element, forming a spiral about the tubular graft with the co-extruded structure, and securing the co-extruded structure to the tubular graft.
