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.
Core Innovation
The invention relates to a coaptation assistance element for treating mal-coaptation of a heart valve having an annulus. The coaptation assistance element includes first and second opposed surfaces, a hub configured to receive a primary anchor, and a plurality of struts spaced around the hub and extending outward from the hub, with at least one strut configured to be implanted within the heart.
The coaptation assistance element further comprises a layer positioned outward from the hub and configured to be a reinforcement layer for one or more secondary anchors. One or more anchor tethers extend through the coaptation assistance element and are configured to guide the one or more secondary anchors toward the coaptation assistance element, placing reinforcement in an outward region relative to the hub.
In another aspect, the first surface comprises a first coaptation surface configured for the anterior leaflet to coapt against. The reinforcement layer for the first coaptation surface extends only along a portion of the second strut, so reinforcement is localized relative to the strut portion in treating mal-coaptation of a heart valve.
Claims Coverage
The document includes two independent claims, each defining a heart-valve coaptation assistance element. Across the independent claims, the main inventive features are a hub receiving a primary anchor with multiple implanted struts, a reinforcement layer positioned outward from the hub, and anchor-tether guided secondary anchors or localized reinforcement for a coaptation surface.
Coaptation assistance element with hub, struts, and reinforcement for secondary anchors guided by anchor tethers
A coaptation assistance element for treating mal-coaptation of a heart valve includes a hub configured to receive a primary anchor, and a plurality of struts spaced around the hub and extending outward from the hub, with at least a first strut and a second strut configured to be implanted within the heart; the element comprises a layer positioned outward from the hub configured to be a reinforcement layer for one or more secondary anchors; and one or more anchor tethers extending through the coaptation assistance element, configured to guide the one or more secondary anchors toward the coaptation assistance element.
Coaptation assistance element with anterior coaptation surface and reinforcement layer localized to a portion of a second strut
A coaptation assistance element for treating mal-coaptation of a heart valve includes first and opposed second surfaces with a first coaptation surface configured for the anterior leaflet to coapt against, a hub, and a plurality of struts spaced around the hub and extending outward from the hub, including a first strut and a second strut configured to be implanted within the heart; wherein the first coaptation surface comprises a layer positioned outward from the hub configured to be a reinforcement layer for the first coaptation surface, wherein the layer extends only along a portion of the second strut.
Overall, claim coverage centers on a coaptation assistance element for mal-coaptation that uses a hub and multiple implanted struts, with reinforcement positioned outward from the hub. One independent claim emphasizes reinforcement for secondary anchors and anchor tethers configured to guide the secondary anchors, while the other independent claim emphasizes an anterior coaptation surface and a reinforcement layer that extends only along a portion of a second strut.
