Abstract: A system including a delivery apparatus, a crimping device, and a loading assembly. The crimping device includes a housing disposed over a distal end portion of the delivery apparatus for receiving a radially expandable and compressible prosthetic heart valve. The housing includes a funnel segment, a pusher member, and an actuator releasably coupled to the pusher member. Movement of the actuator causes the pusher member to advance the prosthetic heart valve through the funnel segment for radially compressing at least a portion of the prosthetic heart valve. Compression of the prosthetic heart valve facilitates secure attachment of the prosthetic heart valve to the delivery apparatus. The loading assembly can include an additional funnel member for fully crimping and loading the prosthetic heart valve into the delivery apparatus for advancement through a patient's vasculature.

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: Guide wire apparatuses and methods. Guide wires may be utilized for guiding a delivery apparatus, for example a transcatheter mitral valve delivery apparatus to replace a native mitral valve. A guide wire may include a core body having a length, and an outer layer having a length and extending around the core body and along the length of the core body. A guide wire may include an intermediate layer positioned between the core body and the outer layer and configured to be retracted relative to the core body and the outer layer along the length of the core body and the length of the outer layer.

Abstract: Apparatuses, systems, and methods for prosthetic valves. An implantation site may comprise a native heart valve or another implantation site in examples. Examples may be utilized for improved anchoring and sealing of flow (e.g., paravalvular leakage) with a native heart valve having calcification. Examples may reduce the possibility of obstruction of a left ventricular outflow tract (LVOT) of a heart, whether resulting from implantation of a prosthetic valve or otherwise.

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: 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.
