Prosthetic heart valve and endoprosthesis comprising a prosthetic heart valve and a stent
First Claim
1. A prosthetic heart valve assembly comprising:
- at least two pieces of tissue comprising;
a distal portion including a leaflet between a first sleeve and a second sleeve; and
a proximal portion having a width less than a width of the distal portion; and
at least two reinforcement elements;
wherein the first sleeve of each piece is coupled to the second sleeve of an adjacent piece to form a commissure of the prosthetic heart valve assembly, and an outer surface of each commissure is covered by one of the reinforcement elements; and
wherein the proximal portion of each piece includes (1) a first side edge extending from the first sleeve to a proximal zigzag edge and (2) a second side edge extending from the second sleeve to the proximal zigzag edge, and wherein the first side edge of each piece is sutured to the second side edge of an adjacent piece.

Abstract
The invention relates to a prosthetic heart valve (100) for an endoprosthesis (1) used in the treatment of a stenotic cardiac valve and/or a cardiac valve insufficiency. The prosthetic heart valve (100) comprises of a plurality of leaflets (102), which consist of a natural and/or synthetic material and have a first opened position for opening the heart chamber and a second closed position for closing the heart chamber, the leaflets (102) being able to switch between their first and second position in response to the blood flow through the heart. In addition, the prosthetic heart valve (100) comprises a leaflet support portion (103), consisting of biological and/or synthetic material for mounting of the prosthetic heart valve (100) to a stent (10), and a bendable transition area (104) which forms a junction between the leaflets (102) and the leaflet support portion (103), the transition area (104) progressing essentially in a U-shaped manner similar to a cusp shape of a natural aortic or pulmonary heart valve for reducing tissue stresses during opening and closing motion of the leaflets (102). The invention further relates to an endoprosthesis (1) comprising a prosthetic heart valve (100) and a stent (10).
