Abstract
Cardiac valve supports and their methods of use.
Claims27
A cardiac valve support adapted for endovascular delivery to a cardiac valve, comprising:
- first and second support elements each having a collapsed delivery configuration and a deployed configuration;
- and wherein at least two bridging members extend from the first support element to the second support element, said bridging members having a delivery configuration and a deployed configuration, wherein said bridging members extend radially inward from the first and second support elements in the deployed configuration.
A cardiac valve support adapted for endovascular delivery to a cardiac valve, comprising:
- first and second support elements each having a collapsed delivery configuration and a deployed configuration;
- and wherein at least two bridging members extend from the first support element to the second support element, said bridging members having a delivery configuration and a deployed configuration, wherein said bridging members extend longitudinally, and without any appreciable radial curvature, between first and second support elements in the deployed configuration.
A system adapted for endovascular delivery or transapical delivery to replace a mitral valve, comprising:
- a cardiac valve support according to any one of the previous claims;
- and
- a replacement heart valve comprising an expandable anchor and a plurality of leaflets adapted to be secured to the cardiac valve support.
A method of replacing a patient's mitral valve, comprising the steps of:
- (a) delivering a valve support to a location near a subject's mitral valve, the valve support comprising a first support element, a second support element, and at least two bridging members extending from the first and second support elements;
- (b) allowing the first support element to unfold from a collapsed configuration to a deployed configuration secured against cardiac tissue in the area of the mitral valve annulus;
- (c) allowing the bridge members to unfold from their delivery configuration to their deployed configuration positioned in general alignment with the coaptation points of the native mitral valve leaflets;
- and
- (d) allowing the second support element to unfold from a collapsed configuration to a deployed configuration secured against cardiac tissue in the area of the mitral valve annulus.
