Abstract:
A stentless heart valve prosthesis to be used for the replacement of a diseased atrioventricular valve in the heart of a recipient mammal, comprising:a single unitary body of biologically acceptable non-absorbable flexible membrane configured substantially in the shape of an anatomically correct mitral valve, the membrane forming a hollow inverted truncated cone having a substantially circular base forming an annulus at its first end, said base forming annulus corresponding to the mitral annulus of the heart of the recipient and configured and adapted for suturing into the mitral annulus of the heart of the recipient, the membrane further forming an anterior and posterior leaflet configured substantially in the form of the anterior and posterior leaflets of the natural mitral valve of the heart of the recipient, and the membrane still further forming two narrow extensions at its second end opposite to the annulus where the inverted cone is narrower than at its first end, the extensions substantially configured as anatomically correct cords and adapted to be sutured to the papillary muscle of the heart of the recipient, and two lines of biologically acceptable non-absorbable material, the lines configured and positioned as substantially anatomically correct strut cords of the natural mitral valve, each of said lines being affixed at one end substantially to the base of the truncated cone and at a second end substantially to the extremity of one of the extensions, respectively, whereby after implantation into the heart of the recipient the anterior and posterior leaflets of the prosthesis collapse during systole and form a plurality of scallops in substantial simulation of a natural mitral valve.
