Cardiac valve annulus restraining device
First Claim
1. A system for treating mitral valve regurgitation, the system comprising:
- a catheter;
a flexible restraining device having a plurality of anchor members extendable therefrom;
the anchor members being integrally formed with or fixedly attached to the flexible restraining device;
the anchor members shaped for penetration into the annulus of a mitral valve the anchor members being movable from a delivery configuration to a deployment configuration; and
an adjustment member extending from end portions of the flexible restraining device.

Abstract
A catheter based system for treating mitral valve regurgitation includes a restraining device having a flexible member, a plurality of movable anchor members attached to the outer surface of the flexible member, and an adjustment filament attached to the ends of the flexible member. One embodiment of the invention includes a method for attaching a flexible restraining device to the annulus of a mitral valve, and adjusting the length of the adjustment filament attached to the flexible member of the restraining device, thereby reshaping the mitral valve annulus so that the anterior and posterior leaflets of the mitral valve close during ventricular contraction.

17. A method of treating mitral valve regurgitation, the method comprising:
-
delivering a flexible restraining device, having shape-memory anchor members, to a location adjacent a mitral valve via a catheter;
deploying the flexible restraining device from the distal tip of the catheter thereby causing the flexible restraining device to assume an arcuate configuration;
moving the anchor members from a delivery to a deployment configuration responsive to the deployment of the flexible restraining device;
positioning the flexible restraining device against an annulus of the mitral valve;
inserting the anchor members into the annulus;
altering the shape of the flexible restraining device by altering the radius of the arcuate configuration; and
reshaping the annulus in response to the altering of the radius of the arcuate configuration the flexible restraining device. - View Dependent Claims (18, 19, 20)
