PROSTHETIC INSERT FOR TREATING A MITRAL VALVE
First Claim
1. A device for treating a mitral valve, comprising:
- a collapsible and expandable prosthetic insert member having an elongated cross-sectional profile, the insert member shaped for contacting the leaflets of the mitral valve, the insert member formed with a passageway and a valve member disposed within the passageway for allowing blood to flow through the insert member from the left atrium to the left ventricle;
an anchoring member coupled to the insert member, the anchoring member comprising an elongated body portion; and
a penetration member adapted for engaging tissue along a wall of the left ventricle, the penetration member coupled to a bottom end of the elongated body portion.

Abstract
A prosthetic insert member for improving the function of a mitral valve is disclosed. The insert member is configured for insertion between leaflets of mitral valve. The insert member has an elongated cross-sectional profile for conforming to the opening in the mitral valve. The device also includes an anchoring member for attachment to heart tissue for maintaining the insert member in the mitral valve. In operation, the insert member fills the opening between the leaflets of the mitral valve and reduces regurgitation while preferably allowing the leaflets to function in a substantially normal manner. In one embodiment, the insert member is formed with a valve member disposed in a passageway for allowing blood to pass through the insert member in one direction.

8. A system for treating a mitral valve, comprising:
-
a delivery catheter; a prosthetic insert member having a collapsed state and an expanded state, wherein the insert member has an elongated cross-sectional profile in the expanded state for insertion between the leaflets of the mitral valve, the insert member adapted for plugging a gap between the leaflets of the mitral valve and reducing regurgitation, the insert member having an outer surface formed with biological tissue; an anchoring member coupled to the insert member, the anchoring member comprising an elongated body portion; and a penetration member adapted for engaging tissue along a wall of the left ventricle, the penetration member coupled to a bottom end of the elongated body portion. - View Dependent Claims (9, 10, 11, 13, 14)
