洗い流し機能が改善された人工弁
Document Type and Number:
Japanese Patent JP7295358
Kind Code:
B2
Abstract:
Described embodiments are directed toward prosthetic valves having a support structure and at least one leaflet. The leaflet comprises means for allowing fluid that is behind the leaflet to pass through to the front of the leaflet when the leaflet is not in the closed position. The prosthetic valve includes a leaflet moveable between an open position that permits antegrade flow through the prosthetic valve and a closed position that prevents regurgitant flow through the prosthetic valve, the leaflet having an aperture or gap, or a separation of portions of the leaflet to allow a flow or exchange of fluid between a front and back of the leaflet, when the leaflet is not in the closed position.
