1. A system for improving the function of a heart valve, the system comprising:
- a device, the device comprising;
a first support, wherein the first support is configured to abut a first side of said heart valve,a second support, wherein the second support is configured to abut a second side of said heart valve opposite said first side,each of said first and second supports constituted by no more than one complete loop of support materiala connector releasably connecting a first end of said first support and a second end of said second support such that the first and second supports and the connector have a coil shape;
wherein said first and second supports constitute the only supports of said device; and
,wherein opposed surfaces of said first and second supports are configured to provide a pinch to trap valve tissue of said heart valve;
wherein the pinch is sufficiently strong to maintain a remodeled shape of the heart valve.

Abstract
A device for improving the function of a heart valve comprises a first loop-shaped support, which is configured to abut a first side of the heart valve, and a second loop-shaped support, which is configured to abut a second side of the heart valve opposite to said first side, whereby a portion of the valve tissue is trapped between the first and second supports. An outer boundary of the second support is greater than an outer boundary of the first support.

8. A system for improving the function of a heart valve, the system comprising:
-
a device, the device comprising; a first curvilinear support, wherein the first curvilinear support is configured to abut a first side of the heart valve, a second curvilinear support, wherein the second curvilinear support is configured to abut a second side of the heart valve opposite to said first side of the heart valve, each of said first and second curvilinear supports constituted by no more than one complete revolution of support material a connector releasably connecting a first end of said first curvilinear support and a second end of said second curvilinear support such that said first and second curvilinear supports and the connector have a coil shape; wherein said first and second curvilinear supports constitute the only curvilinear supports of said device; and
,wherein said first and second curvilinear supports are configured to provide a constant pinch to trap valve tissue therebetween over the entire valve. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system for improving the function of a heart valve comprised of valve tissue including an annulus and a plurality of leaflets, the system comprising:
-
a device, the device comprising; a first loop-shaped support, wherein the entire first loop-shaped support is configured to abut a first side of the heart valve, a second loop-shaped support, wherein the entire second loop-shaped support is configured to abut a second side of the heart valve opposite to said first side, each of said first loop-shaped support and said second loop-shaped support constituted by no more than one complete loop; whereby opposed surfaces of said first and second loop-shaped supports provide a pinch configured to trap a portion of the valve tissue between the first loop-shaped support and second loop-shaped support, and a connecting part for connecting an end of the first loop-shaped support to an end of the second loop-shaped support such that the first and second loop-shaped supports and the connecting part form a coil-shape wherein the connecting part is releasably attached to at least one of the first and second loop-shaped supports for disconnecting the end of the first loop-shaped support from the end of the second loop-shaped support after insertion to the heart valve; wherein said first looped-shaped support and said second loop-shaped support constitute the only loop-shaped supports of said device. - View Dependent Claims (16, 17, 18, 19, 20, 21)
