摘要： A valve repair system, preferably including an annuloplasty prosthesis and a holder for the prosthesis. The holder includes a first component having a central opening, a circumferential surface and an outwardly extending member. The annuloplasty prosthesis is located adjacent to the circumferential surface, above the outwardly extending member. The holder further includes a second component movable upwardly relative to the first holder component and includes a rigid penetrating member extending downward from the second component into the prosthesis, holding it adjacent the circumferential surface. The holder also includes a suturing guide for assisting a physician in valve repair surgery, which may be a cuttable suture extending across the central opening along a path approximating a desired line of leaflet coaption. The cuttable suture may additionally secure the first and second components to one another. The suturing guide may also be incorporated into one-piece annuloplasty prosthesis holders or into stand-alone tools that do not carry annuloplasty prostheses.

摘要： A multi-leaflet valve adapted to serve as a prosthesis for diseased native valve of a mammal is incorporated in self-expandable or inflatable endovascular stents or stents to form a combination which is introduced on a catheter with a guide wire into the circulatory system of the mammal to replace the diseased native valve. Once the combination is at the desired location the stent is caused to expand and affix itself to the patient's vessel wall. The prosthetic 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 circular support is affixed in a substantially circular fashion around the truncated cone in proximity of the inflow orifice, and a second flexible circular support is affixed at the location of the commissures to form a circle around the truncated cone in proximity of the outflow orifice. The circular supports maintain the shape of the valve during the surgical implantation procedure and thereafter.
