Each heart valve prosthesis is supported and fixed by three identical pairs of brackets (3,4,5) staggered by 120 degrees from each other and joined by solid body links (7). The two curved brackets in opposite facing directions have lever arms of the same length. The first and second distal brackets are partly curved in the same direction and run parallel with each other so that gaps for inserting parts of the cardiac valve prosthesis are formed. |
