PROSTHETIC INSERT FOR IMPROVING HEART VALVE FUNCTION
First Claim
Patent Images
1. A device for improving the function of a heart valve, comprising:
- an insert member comprising a body configured for insertion between leaflets of the heart valve, the body having at least first and second solid leaflet-contacting surfaces; and
an anchoring member coupled to the insert member, the anchoring member comprising a stent having an open-frame structure configured to be radially compressible to a compressed state for delivery to a deployment site adjacent the heart valve and radially expandable to an expanded state at the deployment site,wherein each of the leaflet-contacting surfaces is configured to contact a leaflet of the heart valve when the heart valve closes to minimize regurgitation through the heart valve.

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.
