Abstract: A stabilizer for use with a delivery system is provided. The stabilizer receives a delivery system, such as a handle portion, and prevents unwanted movement of the delivery system during a medical procedure. The stabilizer desirably includes an elongate rail that is adapted to be secured to a base or table. A rail dock is adapted to releasably couple to the delivery system. The rail dock is slidably mounted along an upper surface of the rail and includes a brake assembly. The brake assembly preferably includes a toggle member with at least one push button, wherein actuation of the push button may release or lock the brake assembly. Components of the stabilizer are provided for allowing the stabilizer to be used with different delivery systems and the stabilizer is capable of being secured to different sized tables.

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: 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: Disclosed herein are embodiments of a delivery system which can be used to recapture and/or reposition a replacement valve, such as a replacement mitral valve, after initial deployment of the valve. Embodiments of the delivery system can involve a torqueing manifold that interacts with multiple tethers that are releasably coupled to eyelets of a replacement heart valve. Engagement pins may be configured to releasably retain one end of the tethers.

Abstract: Disclosed herein are embodiments of a delivery system which can be used to recapture and/or reposition a replacement valve, such as a replacement mitral valve, after initial deployment of the valve. Embodiments of the disclosure can use the crimping/tensioning of sutures in order to re-crimp the replacement valve after release, though longitudinal or rotational forces.

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: 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.
