Problems solved by technology

Such anchoring devices may limit the ability to crimp the prosthetic valve, which may increase the overall crimp profile of the prosthetic valve
Prior art anchoring devices also tend to increase the stiffness of the prosthetic valve in a crimped state, which may limit the ability to bend / steer the delivery catheter within the patient's vasculature
Furthermore, prior art anchoring devices may also be difficult to place at their desired anchoring location due to the presence of subvalvular tissue

Abstract

In one representative embodiment, a prosthetic valve assembly includes a valve component including a radially compressible and expandable frame and a valve structure supported within the frame. The valve structure is configured to allow blood to flow through the valve member in one direction and to block blood flow in the opposite direction. The assembly further includes a radially compressible and expandable anchor comprising an annular base and a plurality of cantilevered fixation members extending from the base. The fixation member is configured to pivot inwardly toward the valve component when the valve component is radially expanded within the anchor.

Description

technical field [0001] The present disclosure relates generally to prosthetic devices for repairing and / or replacing native heart valves, and in particular to prosthetic valves for replacing defective mitral valves, and for delivering and implanting such prosthetic valves in the human heart Methods and devices within. Background technique [0002] Prosthetic valves have been used for many years to treat heart valve disorders. Native heart valves (ie, aortic, pulmonary, tricuspid, and mitral valves) perform a number of critical functions in ensuring an adequate blood supply for forward flow through the cardiovascular system. These heart valves may be rendered less effective due to congenital malformations, inflammatory processes, infectious conditions, or disease. Such damage to the valve can lead to serious cardiovascular harm or death. For many years, the definitive treatment for such disorders has been surgical repair or replacement of the valve during open heart surger...
