Abstract
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation enhancement element for implantation across the valve; a system including the coaptation enhancement element and anchors for implantation; a system including the coaptation enhancement element, catheter and driver; and a method for transcatheter implantation of a coaptation element across a heart valve.
Claims22
1-17. (canceled)
A coaptation implant comprising:
- a coaptation surface configured for an anterior leaflet of a valve to coapt against;
- a superior edge, lateral edges, and an inferior edge, wherein the superior edge has a length greater than a length of the inferior edge, such that a transverse distance between lateral edges generally decreases from the superior edge to the inferior edge of the coaptation implant;
- at least one strut arranged to assist in maintaining the shape of the coaptation implant upon placement, while still allowing the coaptation implant to assume a reduced configuration for deployment through a catheter.
A coaptation implant comprising:
- a coaptation surface configured for an anterior leaflet of a valve to coapt against;
- a superior edge, lateral edges, and an inferior edge, wherein the superior edge has a length greater than a length of the inferior edge, such that a transverse distance between lateral edges generally decreases from the superior edge to the inferior edge of the coaptation implant;
- one or more struts, wherein the one or more struts curve laterally toward the superior edge to assist in maintaining the shape of a proximal portion upon deployment.
A coaptation implant comprising:
- a coaptation surface configured for an anterior leaflet of a valve to coapt against;
- a superior edge, lateral edges, and an inferior edge, wherein the superior edge has a length greater than a length of the inferior edge, such that a transverse distance between lateral edges generally decreases from the superior edge to the inferior edge of the coaptation implant;
- one or more struts connected to a hub, wherein the hub is coupleable with an anchor or anchoring element.
