摘要:
An apparatus and method for forming or shaping an intraluminal stent for low profile delivery into a body lumen. A nickel titanium intraluminal stent has a tubular member formed from a plurality of coils which are bent to form lobe-shaped members, like a cloverleaf, to reduce the profile of the tubular member and form an involuted spring stent. The involuted spring stent will transform to the implanted diameter of the tubular member when exposed to body heat. The involuted spring stent can be attached to a tubular graft, or coated with a polymeric material to form an involuted spring graft, both of which can be used to repair aortic aneurysms.
