Abstract

Die Herzklappe (1) einen ringförmigen Körper (2) zur Verankerung der Herzklappe (1) im menschlichen Körper auf mit einem von dem ringförmigen Körper (2) in seinem Zentrum aufgespannten Lumen (5). In dem ringförmigen Körper (5) ist mindestens ein Schließkörper (8) gelagert, der um eine Schwenkachse (13) von einer Of fen-Stellung in eine Geschlossen-Stellung, drehbar ist. Der Schließkörper (8) weist zumindest ein Lagerstück (16) auf und ist dadurch am ringförmigen Körper (2) gelagert, wobei jedes Lagerstück (16) in einer ihm zugeordneten Lagervertiefung (14) des ringförmigen Körpers (2) angeordnet ist. Jede Lagervertiefung (14) weist einen Lagergrund (9) auf, auf dem das Lagerstück (16) gleitet, wobei der Lagergrund (9) nicht eben, sondern als konvexe oder konkave Fläche ausgebildet ist. Die Lage der Schwenkachse des Schließkörper relativ zu dem ringförmigen Körper kann von dem Öffnungswinkel (small omega) des Schließkörper abhängen.
