GEOMETRIC CONTROL OF BENDING CHARACTER IN PROSTHETIC HEART VALVE LEAFLETS

摘要

The described embodiments relate to artificial valves with leaflets of a specific shape that control bending properties. According to one embodiment, the artificial valve includes a number of leaflets. Each leaflet includes a central region and two side regions on either side of the central region. The central region is defined by a substantially isosceles triangular shape defined by two central region sides, leaf base and leaf free edge, the two central region sides gather from the leaf base, each of the two side regions has a substantially triangular shape and each It is defined by one of the central area sides, one of the leaflet sides, and the leaflet free edge.
