CARDIAC VALVE SUPPORT DEVICE FITTED WITH VALVE LEAFLETS
First Claim
1. 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;
and wherein one of said support elements is fitted with one or more valve leaflets.

Abstract
The present invention provides a cardiac valve support device adapted for endovascular delivery to a cardiac valve, wherein said support device comprises either a single support element with valve leaflets connected thereto or two interconnected support elements having valve leaflets connected to one of said two elements. The invention further encompasses a two-stage method for implanting a replacement cardiac valve, wherein the first stage comprises delivering a valve support device fitted with one or more valve leaflets to a location near a subject'"'"'s cardiac valve, such that said valve leaflets fulfill the function previously fulfilled by the native valve.

2. A cardiac valve support adapted for endovascular delivery to a cardiac valve, comprising a single ring-shaped support element, wherein said support element has a collapsed delivery configuration and a deployed configuration, and wherein said support element is fitted with one or more valve leaflets.
-
11. A two-stage method for implanting a replacement cardiac valve,
wherein the first stage comprises delivering a valve support device comprising one or more support elements and one or more valve leaflets attached to one of said support elements, to a location near a subject'"'"'s cardiac valve, expanding said support element(s) from a collapsed delivery configuration to an expanded, deployed configuration secured against cardiac tissue in the region of the valve annulus, thereby permitting said valve leaflets to fulfill the function previously fulfilled by the native valve; and wherein the second stage comprises deploying a replacement valve within the central space of said valve support and securing said valve thereto. - View Dependent Claims (12, 13, 14)
