Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. In embodiments, a prosthetic heart valve assembly, including a self-expandable support structure and a self-expanding heart valve, are advanced through the aortic arch of a patient using a delivery system. The support structure, which includes a plurality leaflet retaining arms, is at least partially expanded and positioned on or adjacent to the outflow side of the aortic valve. The prosthetic heart valve is positioned in the aortic valve. The prosthetic heart valve is expanded while it is within an interior of the support structure and while the support structure is positioned on or adjacent to the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the arms of the support structure and the expanded prosthetic heart valve.

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.
