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: Delivery devices and methods for delivering a prosthetic heart valve. The delivery device includes an inner shaft assembly with a valve retainer, an outer shaft assembly, a handle assembly and an axial force adjustment assembly. The outer shaft assembly includes a capsule containing the prosthetic valve in a loaded state. The handle assembly is coupled to a proximal region of the outer shaft assembly. The axial force adjustment assembly connects a proximal section of the inner shaft assembly to the handle assembly, and is configured to selectively move the proximal section relative to the handle assembly. The axial force adjustment assembly can include an actuator member and a driver member. The driver member directly interfaces with the inner shaft assembly, and a force applied to the actuator member is transferred onto the proximal section via the driver member. A sensor for sensing tension and/or compression in the inner shaft assembly can be provided.
