Abstract

A device and methods for improving the function of a heart valve, such as an aortic valve, is disclosed. In one embodiment, the device includes an insert member configured for insertion between leaflets of an aortic valve. The insert member preferably includes three radial arms extending outwardly from a central portion. The device also includes an anchoring member which is coupled to the insert member and configured for maintaining the insert member within the heart valve. In operation, each of the arms fills gaps between heart valve leaflets, thereby minimizing or preventing regurgitation through the heart valve.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 60 / 810,085, filed June 1, 2006, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to the field of implantable cardiac prosthetics and, in particular, to cardiac prosthetic inserts for reducing regurgitation through a heart valve, such as the aortic valve, and to methods of implanting a cardiac prosthetic insert. Background technique [0004] Heart valve regurgitation, or leakage from the outflow side of a heart valve to the inflow side, is a condition that occurs when a heart valve fails to close properly. Heart valve regurgitation reduces the efficiency of the heart, reduces blood circulation, and increases stress on the heart. Early on, heart valve regurgitation makes a person feel tired and short of breath. If left unchecked, this problem can lead to congestive heart failure...
