Abstract:
1. A combination of an endovascular stent with an intravascular multi-leaflet, one-way valve to serve as a prosthesis for diseased native valve of a mammal, the combination being adapted for percutaneous delivery, and comprising: (1) a valve including a tubular member formed of one of a naturally occurring tubular body channel and of a membrane, the membrane being selected from a group of materials consisting of biocompatible polymer and biologic flat membrane, said membrane formed into the tubular member and configured as a truncated cone, the tubular member having an inflow orifice and an outflow orifice, the leaflets forming the outflow orifice and forming a plurality of comissures; a first encircling support consisting essentially of material selected from the group consisting of thin metal wire, thin plastic ring, or suture filament, said first encircling support being affixed in a substantially circular fashion around the tubular member in proximity of the inflow orifice, and a second encircling support consisting essentially of material selected from the group consisting of thin metal wire, thin plastic ring, or suture filament, said second encircling support being affixed solely at the locations of the comissures to form a circle around the tubular member in proximity of the outflow orifice; (2) an endovascular stent larger in diameter than the valve, the valve being contained in the endovascular stent and attached to the endovascular stent by affixing the inflow orifice of the valve to the endovasular stent and by affixing the second encircling support to the endovascular stent, the endovascular stent including an outwardly extended bulge in an area where the valve is attached within the endovacular stent, said bulge corresponding to the sinuses of Valsalva.
