Abstract
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.
Claims20
A coaptation assistance element for treating mal-coaptation of a heart valve, the heart valve having an annulus, the coaptation assistance element comprising:
- a first surface and an opposed second surface, each surface bounded by a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- a hub;
- and
- a plurality of struts spaced around the hub and extending outward from the hub, the plurality of struts comprising at least a first strut configured to be implanted within a heart superior to a valve annulus and a second strut configured to be implanted within a heart and traversing a plane of the valve annulus,
- wherein the coaptation assistance element comprises a multi-layer laminate covering at least a portion of the plurality of struts.
A coaptation assistance element for treating mal-coaptation of a heart valve, the heart valve having an annulus, the coaptation assistance element comprising:
- a first coaptation surface and an opposed second surface, each surface bounded by a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- a hub;
- an anchor coupled to the hub and configured to be rotated relative to the hub to selectively deploy the anchor at a first target location;
- and
- a plurality of struts spaced around the hub and extending outward from the hub, the plurality of struts comprising at least a first strut configured to be implanted within a heart superior to a valve annulus and a second strut configured to be implanted within a heart and traversing a plane of the valve annulus,
- wherein the coaptation assistance element comprises at least two layers comprising different materials covering at least a portion of the plurality of struts.
A coaptation assistance element for treating mal-coaptation of a heart valve, the heart valve having an annulus, the coaptation assistance element comprising:
- a first coaptation surface and an opposed second surface, each surface bounded by a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- a hub;
- an anchor coupled to the hub, the anchor configured to be rotated in a first direction to selectively deploy the active anchor to engage tissue, the active anchor configured to be rotated in a second direction, opposite the first direction, to selectively disengage tissue;
- and
- a plurality of struts spaced around the hub, the plurality of struts comprising at least a first strut configured to be implanted within a heart superior to a valve annulus and a second strut configured to be implanted within a heart and traversing a plane of the valve annulus
- wherein the coaptation assistance element comprises at least two layers comprising different dimensions covering at least a portion of the plurality of struts.
