Abstract
Abstract An apparatus for the repair of a cardiovascular valve has leaflets comprising a grasper capable of grabbing and co-apting the leaflets of the valve. In a preferred embodiment the grasper has jaws that grasp and immobilize the leaflets, and then a fastener is inserted to co-apt the leaflets. The apparatus is particularly useful for repairing mitral valves to cure mitral regurgitation.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
41 words
1 . A method for coapting cardiac valve leaflets, said method comprising capturing the valve leaflets between two clipping elements, wherein one of said clipping elements has a longer surface in contact with the leaflets than does the other clipping element.
Claim 2
Dependent Claim
41 words

Claim 13
Dependent Claim
44 words
12 . A fastener for use with a system for delivering the faster to coapt leaflets in a heart, said fastener comprising first and second clip elements adapted to close over the leaflets wherein one of the clip elements is longer than the other.
Claim 14
Dependent Claim
44 words
12 . A fastener for use with a system for delivering the faster to coapt leaflets in a heart, said fastener comprising first and second clip elements adapted to close over the leaflets wherein one of the clip elements is longer than the other.
Claim 15
Dependent Claim
27 words
13 . A fastener as in claim 12 , wherein said one clip element is longer than the other when said clips are closed over the leaflets.
Claim 16
Dependent Claim
19 words
14 . A fastener as in claim 12 , wherein said clip elements comprise barbs which engage the leaflets.
Claim 17
Dependent Claim
19 words
15 . A fastener as in claim 12 , wherein said clip elements are arranged in a U-shaped clip.
Claim 18
Dependent Claim
55 words
16 . A device for coapting cardiac valve leaflets, said device comprising a grasper having grasping surfaces and operatively configured to grasp the valve leaflets between the grasping surfaces, wherein when said leaflet is grasped, one of said grasping surfaces has a longer surface in contact with the leaflet than does the other grasping surface.
Claim 19
Dependent Claim
55 words
16 . A device for coapting cardiac valve leaflets, said device comprising a grasper having grasping surfaces and operatively configured to grasp the valve leaflets between the grasping surfaces, wherein when said leaflet is grasped, one of said grasping surfaces has a longer surface in contact with the leaflet than does the other grasping surface.
Claim 20
Dependent Claim
14 words
17 . A device of claim 16 , wherein said grasper includes a fastener.
