Abstract: Delivery systems and methods of delivering devices or implants are disclosed. The devices or implants can be configured as valve repair devices or treatment devices have gripping members that are openable and closable to attach the device to leaflets of a native heart valve. The delivery systems are configured to position the device or implant and open and close the gripping members of the device or implant.

Abstract: Components for valve treatment systems are disclosed. Valve treatment systems can include a delivery system for an implantable device. The delivery system can include one or more of clasp control components slidably disposed on a catheter handle, a control element for opening and closing the implantable device, a catheter assembly with features to reduce friction with another catheter assembly, grips for attaching catheter assemblies to clamps, catheter assemblies with features that stiffen or provide variable stiffness, and catheter assemblies with one or more steering control lumens incorporated into a reinforcement layer.

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.
