Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

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 includes a medical device for implanting in a valve of a subject, the implantable medical device having a self-expanding frame; and a holder configured to retain the frame of the implantable medical device in a constricted configuration and to control expansion of the frame. The holder has a controllably constrictable and expandable loop, wherein the loop is disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame.

Abstract: A valve prosthesis includes an expandable frame comprising an outflow portion and an inflow portion connected to the outflow portion. The frame defines a central lumen extending between the outflow portion and the inflow portion. The frame is generally cylindrical in a fully expanded configuration. When the frame is in the fully expanded configuration, an outer surface of the inflow portion is concave. The inflow portion has an upper inflow portion and a lower inflow portion. When the frame is in the fully expanded configuration, the upper inflow portion flares outwardly from the central lumen of the frame to greater extent than the lower inflow portion.
Abstract translation: 瓣膜假体包括可扩张框架，其包括流出部分和连接到流出部分的流入部分。 框架限定在流出部分和流入部分之间延伸的中心腔。 框架通常为圆柱形，处于完全展开的构型。 当框架处于完全展开的构型时，流入部分的外表面是凹的。 流入部具有上流入部和下流入部。 当框架处于完全展开的构造时，上流入部分从框架的中央腔向外扩展到比下流入部分更大的程度。

Abstract: Delivery devices and device elements that provide steering capabilities and methods of steering such delivery devices during the delivery of a stented prosthesis to a target site. Various delivery devices include a shaft assembly having a plurality of lumens through which tension members that compressively retain the stented prosthesis to the shaft assembly are routed. By selectively tensioning one or more tension members, the shaft assembly can be pulled or steered in a desired direction. Various embodiments include one or more steering or stiffening rods that can reinforce the device or counteract any unintended bending or steering of the delivery device.
