TRANSCATHETER MITRAL VALVE AND DELIVERY SYSTEM

摘要

A prosthetic heart valve includes a collapsible and expandable stent, a collapsible and expandable valve assembly disposed within the stent, and one or more features coupled to the stent for at least partially anchoring the prosthetic heart valve within a native valve annulus of a patient. The anchoring features may include a body transitionable from an unfurled condition to a furled condition, the furled condition forming a flange for at least partially anchoring the heart valve, and/or a plurality of hooks transitionable from a deformed condition to a relaxed condition for at least partially anchoring the heart valve. A delivery device for the prosthetic heart valve may include a handle and a catheter member extending from the handle and having a first portion, a second portion, and a compartment for receiving the valve. The delivery device may provide for staged deployment of the valve.
