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 of a heart, the coaptation assistance element comprising:
- a first coaptation surface and an opposed second surface;
- a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- a hub spaced inward from each of the first lateral edge, the second lateral edge, the inferior edge, and the superior edge;
- and
- an active anchor configured to couple 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 around the hub and extending outward from the hub, the plurality of struts comprising at least a first strut configured to be implanted within the heart and a second strut configured to be implanted within the heart such that the first coaptation surface coapts with a first leaflet of the heart valve and the opposed second surface overlays a second leaflet of the heart valve.
A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the coaptation assistance element comprising:
- a first coaptation surface and an opposed second surface;
- a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- a hub;
- an anchor configured to be coupled to the hub, the anchor configured to be rotated in a first direction relative to the hub to engage a tissue at a first target location, the anchor configured to be rotated in a second direction, opposite the first direction, relative to the hub to selectively disengage the tissue at the first target location;
- and
- a plurality of struts extending outward from the hub, the plurality of struts comprising at least a first strut configured to be implanted within the heart superior to the heart valve and a second strut configured to be implanted within the heart and traversing the heart valve.
A coaptation assistance element for treating mal-coaptation of a heart valve of a heart, the heart valve having an annulus, the coaptation assistance element comprising:
- a first coaptation surface and an opposed second surface;
- a first lateral edge, a second lateral edge, an inferior edge, and a superior edge;
- a hub;
- an annular anchor configured to be coupled to the hub and configured to be rotated relative to the hub to selectively deploy the annular anchor at a first target location, wherein the hub is configured to remain stationary as the annular anchor is rotated to engage tissue;
- 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 the heart and a second strut configured to be implanted within the heart to position the annular anchor near the annulus.
