Abstract: Prosthetic heart valve assemblies and methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. A prosthetic heart valve assembly includes an inner frame, a prosthetic leaflet section disposed within the inner frame extending between in inflow row of cells and an outflow row of cells of the inner frame, and an outer support stent. The inner frame is disposed within the outer support stent, and the outer support stent is coupled and/or fastened to the inner frame. The outer support stent includes a plurality leaflet capturing arms for capturing native leaflets between the leaflet capturing arms and a portion of the prosthetic heart valve assembly when the prosthetic heart valve assembly is implanted in a native valve. For example, the native leaflets can be frictionally secured between the leaflet capturing arms of the support stent and the inner frame.

Abstract: This application relates to methods, systems, and apparatus for replacing native heart valves with prosthetic heart valves and treating valvular insufficiency. In some implementations, a heart valve leaflet clipping mechanism includes a delivery apparatus and clipping arms. The clipping arms are coupled to the delivery apparatus. The clipping arms are movable between an open position and a closed position. The two clipping arms are biased to the closed position. The delivery apparatus is configured to hold the clipping arms in the open position. The delivery apparatus is configured to allow the clipping arms to move to the closed position to engage native heart valve leaflet tissue.

Abstract: This application relates to methods, systems, and apparatus for replacing native heart valves with prosthetic heart valves and treating valvular insufficiency. In a representative embodiment, a support frame configured to be implanted in a heart valve comprises a main body formed by formed by a plurality of inner members forming an inner clover and a plurality of outer members forming an outer clover. The support frame can include gaps located between inner members of the plurality of inner members and outer members of the plurality of outer members. The inner clover can be radially inside the outer clover, and the outer clover can have larger dimensions than the inner clover. The support frames herein can be radially expandable and collapsible.

Abstract: Devices and related methods of use are provided for improving heart function. In one embodiment of the present disclosure, a device includes a ring-like structure configured to be secured to a heart valve; at least one elongate member extending from the ring-like structure, wherein an end of the elongate member is configured to be secured to heart geometry other than a heart valve; and an adjustment mechanism for simultaneously altering a dimension of the ring-like structure and a length of the elongate member.

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: A prosthetic remodeling annuloplasty ring for use in tricuspid or mitral valve repairs to provide support after annuloplasty surgery. The annuloplasty ring includes a relatively rigid core extending around an axis that is discontinuous to define two free ends. A suture-permeable interface surrounding the core includes floppy regions adjacent both free ends of the core. Sutures are used to attach the annuloplasty ring to the annulus, including at least one suture through each of the floppy regions to secure the free ends of the ring and minimize the risk of ring dehiscence, or pull through of the sutures through the annulus tissue. The floppy regions may project from each free end into the gap toward each other, be radially enlarged such as paddle-like extensions, or may comprise outwardly lateral extensions at the free ends of the core.
