Stent tissue graft prosthesis

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.
