摘要: A replacement heart valve can have an expandable frame configured to engage a native valve annulus. A valve body can be mounted onto the expandable frame to provide functionality similar to a natural valve. The valve body has an upstream end and a downstream end, and a diameter at the downstream end is greater than a diameter at the upstream end.

摘要: A replacement valve has an expandable frame configured to engage a native valve and a valve body mounted to the expandable frame. The valve body can have a plurality of valve leaflets configured to open to allow flow in a first direction and engage one another so as to close and prevent flow in a second direction, the second direction being opposite the first direction.
