Abstract

Abstract Devices for repairing and replacing a heart valve in various embodiments, the devices include at least first and second support rings connected together in a coiled configuration to abut opposite sides of a valve annulus. A replacement valve may be secured to the coil-shaped device. Various alternative fastening systems include suture fastening systems, mechanical fastening systems, shape memory alloy fastening systems and other fastening systems relying only on the resilience between adjacent coils. A method generally includes inserting a first end of the coil-shaped member through a valve annulus, rotating a first ring of the coil-shaped member into position on one side of the valve annulus and positioning at least a second ring of the coil-shaped member on an opposite side of the valve annulus.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 88 words
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: a valve support device configured for attachment to at least one side of the heart valve, and a coil-shaped carrier removably coupled with said valve support device for allowing said valve support device to be turned into position on said at least one side and secured to a portion of the valve tissue to support the heart valve.
Claim 2
Dependent Claim 88 words
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: a valve support device configured for attachment to at least one side of the heart valve, and a coil-shaped carrier removably coupled with said valve support device for allowing said valve support device to be turned into position on said at least one side and secured to a portion of the valve tissue to support the heart valve.
Claim 3
Dependent Claim 77 words
2 . 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: a catheter having a lumen and an open end, an 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.
Claim 4
Dependent Claim 77 words
2 . 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: a catheter having a lumen and an open end, an 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.
Claim 5
Dependent Claim 36 words

Dependent Claim 20 words
4 . The device of claim 2 , wherein said elongate valve support member has a generally triangular-shaped cross section.
Claim 7
Dependent Claim 27 words
5 . The device of 2 further comprising: an actuator carried within said lumen and operable to extend said elongate valve support member from said open end.
Claim 8
Dependent Claim 27 words
5 . The device of 2 further comprising: an actuator carried within said lumen and operable to extend said elongate valve support member from said open end.
Claim 9
Dependent Claim 31 words
6 . The device of claim 5 , wherein said actuator further comprises a gripping element operable to grip and allow releasing of one end of said elongate valve support member.
Claim 10
Dependent Claim 21 words
7 . The device of claim 2 , wherein said elongate valve support member is formed from a shape memory alloy.
Claim 11
Dependent Claim 125 words
8 . 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: a first support member at least partially formed from a shape memory alloy operable to assume an activated shape and an inactivated shape, and a second support member at least partially formed from said shape memory alloy and connected to said first support member, said first support member configured to abut one side of the valve and said second support member configured to abut an opposite side of the valve, whereby a portion of the valve tissue is trapped between said first and second support members upon said shape memory alloy assuming said activated shape.
Claim 12
Dependent Claim 125 words
8 . 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: a first support member at least partially formed from a shape memory alloy operable to assume an activated shape and an inactivated shape, and a second support member at least partially formed from said shape memory alloy and connected to said first support member, said first support member configured to abut one side of the valve and said second support member configured to abut an opposite side of the valve, whereby a portion of the valve tissue is trapped between said first and second support members upon said shape memory alloy assuming said activated shape.
