ABSTRACT:
A multi-leaflet valve adapted to serve as a prosthesis for diseased native valve of a mammal is constructed of biologic membrane or of biocompatible synthetic membrane. The valve has the shape of a truncated cone that has an inflow and an outflow orifice with leaflets forming the outflow orifice and forming a plurality of commissures. A first flexible stent is removably affixed in a substantially circular fashion around the truncated cone in proximity of the inflow orifice, and a second flexible stent is removably affixed at the location of the commissures to form a circle around the truncated cone in proximity of the outflow orifice. The stents maintain the shape of the valve during the surgical implantation procedure. Each stent independently can be left in the valve or can be removed during the implantation procedure based upon the judgement of the cardiac surgeon performing the implantation procedure. A holder designed to maintain the geometry of the valve during implantation to a mammal is also disclosed.
