PERCUTANEOUS HEART VALVE, SYSTEM, AND METHOD

摘要

Devices, systems, and methods are provided to treat diseased cardiac valves. The device includes a percutaneous heart valve (100) having an expandable valve frame (102) including valve frame members (105), a valve leaflet (132) coupled to the valve frame, and an expandable stent anchoring frame (104) coupled to the valve frame including stent frame members (106) defining a first portion (108) and a second portion (110) 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.
