Device, system, and method for transcatheter treatment of valvular regurgitation

摘要

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.

主权项

1. A coaptation assistance element for treating mal-coaptation of a heart valve of a heat, the heart valve having a valve annulus, the coaptation assistance element comprising:
a first coaptation surface and an opposed second surface, each of the first coaptation surface and the opposed second surface bounded by a first lateral edge, a second lateral edge, an inferior edge, and a superior edge, the superior edge forming a lip cupped downward toward the inferior edge or upward from the inferior edge; a hub spaced radially inward from each of the first lateral edge, the second lateral edge, the inferior edge, and the superior edge; and an active anchor coupled to the hub and configured to be rotated relative to the hub to selectively deploy the active anchor at a first target location; and a plurality of struts spaced circumferentially around the hub and extending radially outward from the hub, the plurality of struts comprising at least a first strut configured to be implanted within the heart superior to the valve annulus and a second strut configured to be implanted within the heart and traversing a plane of the valve annulus, wherein the second strut has a total length that is longer than a total length of the first strut.
