US 2026/0248613 A1 · ATRIOVENTRICULAR REGURGITATION REDUCTION SYSTEM ANCHORS

Abstract

Devices for anchoring catheter systems, such as an atrioventricular heart valve regurgitation reduction system with a coapting element or spacer positioned within the atrioventricular valve leaflets. The spacer may be anchored above the atrioventricular valve with a rail that extends up into the subclavian vein, with tethers that attach to anchors around the annulus, or with a tether that connects to a stent expanded within an adjacent blood flow passage. The spacer may also be anchored below the atrioventricular valve with a rail that terminates in a tissue anchor within the ventricle, with tethers that attach to anchors around ventricle, or with a tether that connects to a stent expanded within an adjacent blood flow passage. The spacer may also be stabilized by a harness extending across the valve annulus or may be self-anchoring with an array of struts that extend into contact with the surrounding tissue.

Dependent claims

A device usable for treating regurgitation of a heart valve, the device comprising:

a spacer comprising a proximal portion and a distal portion;
a plurality of curved struts, a strut of the plurality of curved struts having a first end portion and a second end portion, the first end portion couplable to the proximal portion of the spacer and extending towards an annulus of a valve;
and
a plurality of tissue anchors, wherein a tissue anchor of the plurality of tissue anchors is disposed on the second end portion of the strut,
wherein the plurality of tissue anchors are configured to be secured to an annulus of the heart valve such that the plurality of curved struts suspend the spacer centrally within the valve.
