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: 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: 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.
