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: Valvular regurgitation is addressed by implanting devices at or near a native valve to treat leaflet issues. This can be done by treating the leaflets and/or by treating one or more natural chordae tendineae (chords). Treating the leaflets can include methods and devices that bring different leaflets together, and/or inhibiting or arresting a leaflet from billowing and/or flailing into the atrium. Treating the chords can include methods and devices that shorten chords, that increase tension in the chords, that attach chords to the ventricle wall or to each other, and the like. In each of the disclosed methods and devices, coaptation is increased and/or valvular regurgitation is reduced. The disclosed devices and methods can be performed on a beating heart.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The steerable delivery system can contain a steerable rail configured for multi-plane bending to direct a distal end of the delivery system.

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 include breaking up calcification of a native heart valve to improve deployment to the native heart valve.

Abstract: An implantable device or implant is configured to be positioned within a native heart valve to allow the native heart valve to form a more effective seal. The implantable device can be removed using one or more of a cutting device, a capture device, and a stabilization component. The stabilization component can control the position of the implantable device while the cutting device resects one or more of the leaflets to which the implantable device is engaged.

Abstract: Examples of the present disclosure may be directed to reducing a tension force or a compression force in one or more shafts of the delivery system. An elongate catheter may include the one or more shafts. The tension force or compression force may result from residual tension or compression in a shaft resulting from movement of the shaft. The tension force or compression force may alternatively or in combination result from interacting forces across a plurality of the shafts. The tension force or compression force may hinder the operation of the delivery system and in instances may damage the delivery system. Systems, devices, and methods for reducing the tension force or compression force are disclosed herein.

Abstract: A steerable delivery system is provided for delivering a replacement heart valve to a native heart valve location. The steerable delivery system includes an outer sheath assembly having a capsule along a distal end portion for retaining the replacement heart valve in a compressed configuration. The capsule is constructed to provide both compression resistance and flexibility. The capsule may be formed with an outer polymer layer, a metal middle layer located on a radially inner surface of the outer polymer layer, and an inner liner located on a radially inner surface of the metal middle layer. A fluoroelastomer layer is provided for bonding the inner liner to the metal middle layer. The metal middle layer is preferably a metal hypotube.

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.
