    摘要: A multiple-sided medical device comprises a frame comprising wire or other resilient material and having a series of bends and interconnecting sides. The device has both a flat configuration and a second, folded configuration which a generally serpentine shape. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame using heat or pressure welding crimping, adhesive, or other techniques to form an occlusion device, a stent graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.

    摘要: A stent tissue graft prosthesis (20) for repairing, excluding and/or reinforcing a vessel, duct and the like in a patient. The prosthesis includes an inner expandable stent (21) of which a tissue graft (24) and preferably a multilayered tissue construct (33) is disposed thereon for application to the host tissue of a vessel, duct and the like. The tissue construct includes an extracellular matrix material (36) such as small intestine submucosa (37) for remodeling the host tissue into the prosthesis. The prosthesis further includes an outer tubular member (25) such as an outer expandable stent (44) for retaining the tissue graft on the inner stent. The ends of the inner and outer stents are coincident with or extend beyond the ends of the tissue graft to prevent eversion or fold back of the tissue graft during withdrawal of a delivery catheter in a placement procedure.
