  • Intravascular graft and catheter
    Patent number: 5662702
    Abstract: An intravascular graft for restoring normal blood flow in vessels, or for defining new blood flow pathway in arteries includes a proximal collar to aid in anchoring the graft in place. The graft may contain defects in the graft wall to allow blood flow therethrough. Struts encircling the graft provide structural stability. Additional elements which aid in anchoring the graft in place include barbed collars and graft walls which contain ridges. Additional elements to aid in placement include a drawstring associated with the graft collar. A graft designed for use with vessels configured similarly to the basilar artery contains a cap at the distal end of the graft. A catheter to facilitate placement of intravascular grafts is also disclosed.
