Claims8
A vascular implant prosthesis, comprising:
- a) an exovascular stent comprising:
- a generally elongate cylindrical body, a first end, a second end, and a hollow bore extending longitudinally therethrough;
- a first flange extending perpendicularly about the first end of the stent body;
- a second flange extending perpendicularly about the second end of the stent body;
- a plurality of apertures formed in the stent body to permit flow of fluid therethrough;
- b) a bioprosthetic vascular graft comprising a segment of mammalian blood vessel which has been treated with a chemical fixative known to cross link collagen, said bioprosthetic vascular graft being positioned coaxially within the bore of the stent body and affixed to the first and second end flanges of the stent.
