Heart valve coaptation device
A device for repairing a heart valve includes at least one hollow inner portion, a first flexible outer portion, and a second flexible outer portion. The first flexible outer portion and the second flexible outer portion are connected to the at least one hollow inner portion. The first flexible outer portion and the second flexible outer portion each include a frame formed from a loop of metal. The frames each have a central longitudinal section formed by substantially straight parallel segments and a shaped portion that connects the substantially straight parallel segments. The first flexible outer portion and the at least one hollow inner portion are configured to compress tissue of a first heart valve leaflet therebetween. The second flexible outer portion and the at least one hollow inner portion are configured to compress tissue of a second heart valve leaflet therebetween.
1. A device for repairing a heart valve comprising:
an inner portion comprising two posts each having a lumen non-coaxial with the other;
a first flexible outer portion connected to the inner portion, the first flexible outer portion comprising a first frame formed from a loop of metal, the first frame comprising a central longitudinal section formed by substantially straight parallel segments and a shaped portion that connects the substantially straight parallel segments;
a second flexible outer portion connected to the inner portion, the second flexible outer portion comprising a second frame formed from a loop of metal, the second frame comprising a central longitudinal section formed by substantially straight parallel segments and a shaped portion that connects the substantially straight parallel segments;
wherein the first flexible outer portion and the inner portion are configured to compress tissue of a first heart valve leaflet therebetween; and
wherein the second flexible outer portion and the inner portion are configured to compress tissue of a second heart valve leaflet therebetween.
2. The device of claim 1 wherein the device further comprises a tether connecting the two posts.
3. The device of claim 2 , further comprising a locking member configured to secure the tether and maintain the two posts together, wherein the locking member is secured to at least one of the posts.
4. The device of claim 3 , wherein the locking member comprises an aperture for receiving the tether, whereby the tether can be secured relative to the locking member by reducing the size of the aperture such that sides of the aperture securely engage the tether.
5. The device of claim 1 , wherein, each frame is sufficiently spaced apart from the inner portion such that a heart valve leaflet can be securely retained therebetween.
6. The device of claim 1 , wherein each of the first and second flexible outer portions comprise a plurality of barbs.
7. The device of claim 1 , wherein the first and the second flexible outer portions are configured to be separately attachable to the first and second heart valve leaflets and moved toward each other in vivo to bring portions of the first and second leaflets into closer proximity to each other.
8. An assembly, comprising:
an elongate delivery catheter comprising at least one lumen; and
a device for repairing a heart valve comprising:
an inner portion comprising two posts each having a lumen non-coaxial with the other;
a first flexible outer portion connected to the inner portion, the first flexible outer portion comprising a first frame formed from a loop of metal, the first frame comprising a central longitudinal section formed by straight parallel segments and a shaped portion that connects the straight parallel segments;
a second flexible outer portion connected to the inner portion, the second flexible outer portion comprising a second frame formed from a loop of metal, the second frame comprising a central longitudinal section formed by straight parallel segments and a shaped portion that connects the straight parallel segments;
wherein the first flexible outer portion and the inner portion are configured to compress tissue of a first heart valve leaflet; and
wherein the second flexible outer portion and the inner portion are configured to compress tissue of a second heart valve leaflet therebetween.
9. The assembly of claim 8 , wherein the first and the second flexible outer portions are configured to be separately attachable to the first and second heart valve leaflets and moved toward each other in vivo to bring portions of the first and second leaflets into closer proximity to each other.
10. A system for repairing a heart valve comprising:
an inner portion comprising two posts each having a lumen non-coaxial with the other;
a first flexible outer portion connected to the inner portion, the first flexible outer portion comprising a first frame formed from a loop of metal, the first frame comprising a central longitudinal section formed by parallel segments and a connection portion that connects the parallel segments;
a second flexible outer portion connected to the inner portion, the second flexible outer portion comprising a second frame formed from a loop of metal, the second frame comprising a central longitudinal section formed by parallel segments and a connection portion that connects the parallel segments;
wherein the first flexible outer portion and the inner portion are configured to compress tissue of a first heart valve leaflet therebetween;
wherein the second flexible outer portion and the inner portion are configured to compress tissue of a second heart valve leaflet therebetween; and
wherein the first flexible outer portion and the second flexible outer portion are configured to be separately attachable to the first and second heart valve leaflets and moved toward each other in vivo to bring portions of the first and second leaflets into closer proximity to each other.
11. The device of claim 10 wherein the device further comprises a tether connecting the two posts.
12. The system of claim 11 , further comprising a lock configured to secure the tether and maintain the two posts together, wherein the lock is secured to at least one of the two posts.
13. The system of claim 12 , wherein the lock comprises an aperture for receiving the tether, whereby the tether can be secured relative to the lock by reducing the size of the aperture such that sides of the aperture securely engage the tether.
14. The system of claim 10 , wherein, each frame is sufficiently spaced apart from the inner portion such that a heart valve leaflet can be securely retained therebetween.
15. The system of claim 10 , wherein each of the first and second flexible outer portions comprise a plurality of barbs.
