  • Transluminally placed expandable graft prosthesis
    Patent number: 4503569
    Abstract: A transluminally placed endovascular graft prosthesis includes a helically wound coil having a generally tubular shape and is made of a shape memory Nitinol alloy having a transition temperature in the range of 115.degree.-125.degree. F. After placement within a body blood vessel and upon heating of the prosthesis to its transition temperature, the prosthesis expands so as to become firmly anchored to the inside wall of the body blood vessel. After expansion the diameter of the lumen of the prosthesis is approximately equal to the diameter of the body blood vessel passageway. The prosthesis may also be used in other body passageways.
