摘要：
Devices, systems, and methods are provided to treat diseased cardiac valves. The device includes a percutaneous heart valve having an expandable valve frame including valve frame members, a valve leaflet coupled to the valve frame, and an expandable stent anchoring frame coupled to the valve frame including stent frame members defining a first portion and a second portion having greater flexibility than the first portion, where the first portion and the valve frame define a length, and where the stent frame members and the valve frame members along the length provide a contiguous surface over which a delivery device can repeatedly slide over the length in its entirety in two longitudinal directions when the first portion and the valve frame are in a partially expanded state during delivery from the delivery device.
