Abstract

Devices and methods utilizing a catheter to remodel soft tissue of a patient and, in a preferred embodiment, to reduce the volume of the left ventricle of a heart. In one embodiment, one or more sutures are passed through a wall of the ventricle. The ends of the one suture and, more preferably, the multiples sutures are drawn together to draw tissue portions towards one another. In another embodiment, tissue remodeling clip is implanted into a wall of the ventricle. Ends of the clip are resiliently biased to move relative to one another to draw tissue portions towards one another. In yet another embodiment, a tissue remodeling anchor includes a base and a plurality of legs attached to the base. The legs of the tissue anchor are implanted into a wall of the ventricle and moved toward one another to draw tissue portions toward one another. A retaining member is positioned on the tissue anchor to prevent the legs from moving apart.

Description

RELATED APPLICATIONS

[0001] This application is related to, and claims priority from, U.S. Provisional Patent Application No. 60 / 627,821, filed Nov. 15, 2004, the entirety of which is hereby incorporated by reference herein and made a part of the present disclosure.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to methods for remodeling soft tissue of a patient and, preferably, for remodeling the left ventricle of a patient's heart. The present invention also relates to systems for accomplishing the preferred methods.

[0004] 2. Description of the Related Art

[0005] Congestive heart failure is a description given to a myriad of symptoms that may be the result of the heart's inability to meet the body's demand for blood flow. Heart failure may be considered as the condition in which an abnormality of cardiac function is responsible for the inability of the heart to pump blood at a rate commensurate with the requirements of the metabol...
