Abstract

Described embodiments are directed toward prosthetic heart valve leaflets of a particular shape that allows redundant coaptation height in the leaflets when a planar segment is present in each leaflet.

Description

[0001] This application is the international application number PCT / US2013 / 075380, the international application date is December 16, 2013, the application number entering the Chinese national phase is 201380065930.9, and the name is "vertical in the plane part of the prosthetic heart valve leaflet The divisional application of the invention patent application in Heshen District. technical field [0002] The present disclosure relates generally to prosthetic valves and more specifically to the geometry of synthetic flexible valve leaflets. Background technique [0003] The durability of composite materials for heart valves under repeated loads of opening and closing depends in part on the distribution of load between the leaflets and the frame. Additionally, significant loading occurs on the leaflets when in the closed position. Mechanical damage to the leaflets can occur, for example, at the mounting edge, where the flexible leaflets are supported by a relatively rigid fra...
