Abstract

A device for repairing a heart valve comprised of valve tissue including an annulus and a plurality of leaflets for allowing and preventing blood flow. The device has an elongate valve support member, configured for attachment to at least one side of the heart valve. The support member is removably coupled with a carrier and has a coiled configuration when secured to a portion of the valve tissue on the attached side of the heart valve to support the heart valve.

Claims (9)

1. A device for repairing a heart valve comprised of valve tissue including an annulus and a plurality of leaflets for allowing and preventing blood flow, the device comprising.

an elongate valve support member configured for attachment to at least one side of the heart valve, said elongate support member is removably coupled with a carrier and, said elongate valve support member has a coiled configuration when secured to a portion of the valve tissue on said at least one side to support the heart valve.
2. The device of claim 1, wherein said carrier is coil-shaped.
3. The device of claim 2, wherein said coil-shaped carrier allows for said support member to be turned into position on said at least one side of said heart valve.
4. The device of claim 1, wherein said carrier comprises a catheter having a lumen and an open end, said elongate valve support member carried within said lumen and movable from said open end, said elongate valve support member having an uncoiled configuration within said lumen and assuming a coiled configuration when extended from said open end.
5. The device of claim 1, wherein said elongate valve support member including an inner core covered by an outer layer, said inner core formed from a more rigid material than said outer layer.
6. The device of claim 1, wherein said elongate valve support member has a generally triangular-shaped cross section.
7. The device of 4 further comprising:

an actuator carried within said lumen and operable to extend said elongate valve support member from said open end.
8. The device of claim 7, wherein said actuator further comprises a gripping element operable to grip and allow releasing of one end of said elongate valve support member.
9. The device of claim 1, wherein said elongate valve support member is formed from a shape memory alloy.
