Abstract
Cardiac valve supports and their methods of use.
Claims34
A cardiac valve support adapted for endovascular delivery to a cardiac valve, comprising:
- a first support element with a collapsed delivery configuration and a deployed configuration;
- a second support element with a collapsed delivery configuration and a deployed configuration;
- a first bridging member extending from the first support element to the second support element, wherein the first bridging member has a delivery configuration and a deployed configuration;
- and
- a second bridging member extending from the first support element to the second support element, wherein the first bridging member has a delivery configuration and a deployed configuration;
- wherein the first and second bridging members extend radially inward from the first and second support elements in the deployed configurations.
3 more elements
A system adapted for endovascular delivery to replace a mitral valve, comprising:
- a cardiac valve support comprising
- a first support element with a collapsed delivery configuration and a deployed configuration;
- a second support element with a collapsed delivery configuration and a deployed configuration;
- a first bridging member extending from the first support element to the second support element, wherein the first bridging member has a delivery configuration and a deployed configuration;
- and
- a second bridging member extending from the first support element to the second support element, wherein the first bridging member has a delivery configuration and a deployed configuration;
- wherein the first and second bridging members extend radially inward from the first and second support elements in the deployed configurations;
- and
- a replacement heart valve comprising an expandable anchor and a plurality of leaflets adapted to be secured to the cardiac valve support.
6 more elements
A method of replacing a patient's mitral valve, comprising:
- endovascularly 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 first and second bridging members extending from the first and second support elements;
- expanding the first support element from a collapsed configuration to a deployed configuration secured against cardiac tissue below the plane of the mitral valve annulus;
- expanding the bridge members from delivery configurations to deployed configurations positioned in general alignment with the coaptation points of the native mitral valve leaflets;
- and
- expanding the second support element from a collapsed configuration to a deployed configuration secured against left atrial tissue above the plane of the mitral valve annulus.
