Patent ID: 8043368

Claim:
A method of repairing a mitral valve in the heart of a patient by correcting an insufficiency of a valve leaflet of the mitral valve, wherein the valve is connected to at least one natural chordae, said method comprising: accessing the patient's mitral valve via at least one of a guide catheter and an interventional tool; securing a first end of a fastening mechanism positioned in the heart by the at least one of a guide catheter and an interventional tool to the valve leaflet; and coupling a second end of the fastening mechanism within a left ventricle of the heart to a cardiac structure other than the mitral valve leaflet such that the fastening mechanism simulates the function of a natural chordae, wherein said method is performed without penetrating through a myocardium, and wherein the at least one of a guide catheter and an interventional tool is removed from the heart such that the fastening mechanism remains coupled to the valve leaflet and the cardiac structure.
