SYSTEMS AND METHODS FOR TRANSCATHETER TREATMENT OF VALVE REGURGITATION

摘要

The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance devices for implantation across the valve; a system including the coaptation enhancement element and anchors for implantation; a system including the coaptation enhancement element, and one or more of the following: transseptal sheath, anchor delivery catheter, implant delivery catheter, and clip delivery catheter; and methods for transcatheter implantation of a coaptation element across a heart valve.

主权项

1. An implant for treating mal-coaptation of a heart valve, the heart valve having an annulus and first and second leaflets with an open configuration and a closed configuration, the implant comprising:
a coaptation assist body having a first coaptation surface configured to be disposed to the posterior leaflet, an opposed second surface configured to be disposed toward the anterior leaflet; at least one ribbon configured to extend from the coaptation assist body, the ribbon comprising a shape memory material having a preformed shape with at least one curve, the ribbon movable from a first compressed configuration to a second expanded configuration, wherein the ribbon is configured to provide a compressive force, the compressive force sufficient to secure the coaptation assist body in the vicinity of the native valve annulus.
