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.

Abstract: Devices and methods for securing a tissue anchor in tissue of a patient, in particular to ensure proper deployment of a cardiac tissue anchor by regulating the force or pressure of a deployment tool against the tissue. One way to ensure proper deployment force is to visualize the distal end of the tissue anchoring catheter from outside the body using a display for an imaging sensor, where the distal end of the catheter changes configuration when it is pressed against the tissue. Another method involves automatically regulating the pressure applied to the tissue prior to deployment of the tissue anchor, which may also be used in conjunction with visualization. Several safety locks to prevent deployment of the tissue anchor prior to establishment of the proper pressure are disclosed, which again may be used with visualization and/or an automated pressure regulator.
