Methods and devices for heart valve treatments
View Patent ↗The present invention is a group of medical devices designed to improve heart valve function. The medical devices may be used individually, or in combination to supplement damaged valves, replace damaged valves, or improve damaged valves function. The medical devices include leaflet retainers, a neo-annulus, neo-leaflet, and a framework. In addition, the present invention is novel methods for surgically treating heart valves.
1. A method comprising
providing a heart implant sized and configured to be positioned in a left atrium above the plane of a native mitral heart valve annulus having leaflets, the implant including a portion sized and configured for engagement with a wall of the left atrium above the plane of the native mitral valve annulus to interact with movement of the leaflets of the mitral heart valve to affect mitral heart valve function,
establishing an intravascular access path that extends from a right atrium through a septum and into a left atrium,
deploying the implant through the intravascular path into the left atrium, and
positioning the implant in the left atrium with the portion engaging a wall of the left atrium above the plane of the native mitral valve annulus such that the portion interacts with movement of the leaflets of the mitral heart valve to affect mitral heart valve function.
2. A method according to claim 1 wherein the implant is positioned so that the portion spans the left atrium.
3. A method according to claim 1 wherein the implant is positioned so that the portion changes the shape of the native mitral heart valve annulus.
4. A method according to claim 1 wherein the heart implant comprises, at least in part, nitinol, dacron, polytetrafluoroethylene, silicon, polyurethane, human pericardium, or animal pericardium.
5. A method according to claim 1 wherein the heart implant comprises, at least in part, a super elastic material.
