ABSTRACT:
A device and method for shortening the chordae tendineae by heating them. Shortening the chordae tendineae stabilizes the atrioventricular valve to which they are attached, thus reducing or halting valve prolapse. A catheter having a heating tip system is inserted in the heart of a patient and maneuvered by an operating surgeon so that the heating tip can induce or transfer heat to the chordae tendineae. The heating tip system heats the chordae tendineae by direct transmission of heat or by inducing heat in the chordae tendineae with electromagnetic radiation. The operating surgeon monitors the heating of the chordae tendineae and when the desired degree of shorting has been achieved, the catheter is removed from the patient.
