    Abstract: Methods for rotationally aligning transcatheter heart valve prosthesis within a native heart valve include percutaneously delivering the transcatheter heart valve prosthesis to the native heart valve, wherein the transcatheter heart valve prosthesis includes at least one imaging marker, receiving a cusp overlap viewing angle image and/or a coronary overlap viewing angle image of the transcatheter heart valve prosthesis within the native heart valve, determining, based on the cusp overlap viewing angle image and/or the coronary overlap viewing angle image and the at least one imaging marker, whether the transcatheter heart valve prosthesis is in a desired rotational orientation, if the at least one imaging marker in the cusp overlap viewing angle image and/or the coronary overlap viewing angle indicates that the transcatheter heart valve prosthesis is not in the desired rotational orientation, rotating the transcatheter heart valve prosthesis until the transcatheter heart valve prosthesis is in the desired rotational orientation.

    Abstract: The disclosure relates to transcatheter stented prosthesis delivery devices including transition elements that route, constrain, support and reduce damage to tension member wear as tension in the tension members is varied to adjust the compression of a stented prosthesis loaded onto the delivery device. Various disclosed tension elements include inserts, edge treatments and guides proximate a distal portion of the delivery device upon which the stented prosthesis is loaded. In some embodiments, the transition feature is positioned proximate a location where at least one tension member transitions from a first orientation that is not parallel to the distal portion to a second orientation that is generally parallel to the distal portion. Further embodiments disclose configurations and methods of selectively locking and unlocking a longitudinal and/or rotational position of the stent frame with respect to the distal portion of the delivery device.

    Abstract: A system for percutaneous delivery of a stented prosthetic heart valve. The system includes a delivery device with a self-expanding prosthetic heart valve attached thereto and a delivery sheath with an opening on a distal end thereof. The delivery sheath includes a funnel on a proximal end thereof. The delivery device is inserted into the funnel of the delivery sheath. As the delivery device is advanced into the funnel, the expanded heart valve is compressed by the shape of the funnel into a crimped arrangement. The delivery device further advances the heart valve distally within the delivery sheath past the delivery sheath opening. The delivery device is advanced relative to the delivery sheath in transitioning the heart valve from a crimped arrangement to the expanded and deployed arrangement.

    Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.

    Abstract: An integrated valve prosthesis includes an anchor stent, a tether component, and a valve component. The anchor stent includes a self-expanding tubular frame member configured to be deployed in the annulus of an aortic valve or the aorta. The valve component includes a valve frame and a prosthetic valve coupled to the valve frame, and is configured to be deployed within the anchor stent. The tether component includes a first end coupled to the anchor stent and a second end coupled to the valve frame. In the delivery configuration, the tether component extends in a first direction from the anchor stent to the valve component, and in the deployed configuration, the tether component extends in a second direction from the anchor stent to the valve component. The second direction is generally opposite the first direction. The tether component may set the location of the valve component relative to the anchor stent.

    Abstract: A transcatheter heart valve prosthesis configured in accordance herewith includes an expandable frame having a plurality of commissure posts extending therefrom, a radially expandable tubular component inflow member attached to the plurality of commissure posts, and a locking mechanism operably coupled to a wire. The wire is at least partially slideably disposed within a channel formed in a wall of the tubular component inflow member and the locking mechanism is configured to permit the wire to be advanced within the channel to thereby transition the inflow member tubular component into a deployed configuration that at least partially engages tissue at the native heart valve.
