Method and apparatus for performing catheter-based annuloplasty
First Claim
1. A method for performing a procedure on a mitral valve of a heart, the method comprising:
- inserting at least one implant into a left ventricle of the heart;
positioning the at least one implant with respect to the mitral valve, wherein positioning the implant includes orienting the implant in the left ventricle substantially below the mitral valve; and
attaching the implant to tissue located near the mitral valve.

Abstract
The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing a procedure on a mitral valve of a heart includes inserting an implant into a left ventricle and orienting the implant in the left ventricle substantially below the mitral valve. The implant and tissue around the mitral valve are connected and tension is provided to the implant, in one embodiment, in order to substantially reduce an arc length associated with the mitral valve. In another embodiment, the implant is inserted into the left ventricle through the aorta and the aortic valve.
