Device, system, and method for transcatheter treatment of valvular regurgitation
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.
1. A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
a first surface and an opposed second surface;
a first lateral edge, a second lateral edge, an inferior edge, and a superior edge; and
a superior zone and an inferior zone, the superior zone configured to reside in the plane of an annulus of the heart valve, the inferior zone extending downward from the superior zone,
wherein the inferior zone comprises a leaflet-apposing valve body element and a leaflet surface, wherein the leaflet-apposing valve body element is configured to increase the distance between the leaflet-apposing valve body element and the leaflet surface in an expanded state.
2. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element comprises a synthetic polymer material.
3. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element comprises a biological material.
4. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element comprises a bioprosthetic valve.
5. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element comprises a coaptation surface.
6. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element comprises a reinforced surface.
7. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element comprises at least one fixed end and at least one free end.
8. The coaptation assistance element of claim 1 , wherein the leaflet-apposing valve body element is configured to mimic the cardiac cycle by movement of the leaflet-apposing valve body element.
9. The coaptation assistance element of claim 1 , wherein the coaptation assistance element comprises struts.
10. The coaptation assistance element of claim 9 , wherein the leaflet-apposing valve body element is coupled to the struts.
11. The coaptation assistance element of claim 1 , wherein the coaptation assistance element comprises a hub.
12. A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
a first surface and an opposed second surface;
a first lateral edge, a second lateral edge, an inferior edge, and a superior edge; and
a superior zone and an inferior zone, the superior zone configured to reside in the plane of an annulus of the heart valve, the inferior zone extending downward from the superior zone,
wherein the inferior zone comprises a leaflet-apposing valve body element configured to expand outward based on the motion of the heart or blood flow or pressure build-up within the heart of the patient.
13. The coaptation assistance element of claim 12 , wherein the leaflet-apposing valve body element is configured to expand and contract with each heartbeat, permitting proper blood flow through the heart valve.
14. The coaptation assistance element of claim 12 , wherein the coaptation assistance element comprises struts.
15. The coaptation assistance element of claim 14 , wherein the leaflet-apposing valve body element is coupled to the struts.
16. The coaptation assistance element of claim 12 , wherein the leaflet-apposing valve body element is flexible.
17. The coaptation assistance element of claim 12 , wherein the leaflet-apposing valve body element is configured to provide a coaptation surface for the anterior leaflet to seal against.
18. The coaptation assistance element of claim 12 , wherein the leaflet-apposing valve body element comprises a permeable material.
19. The coaptation assistance element of claim 12 , wherein the coaptation assistance element is configured to anchored to the annulus.
20. The coaptation assistance element of claim 12 , wherein the coaptation assistance element comprises a hub.
