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: An embolic protection device includes a shaft, a first magnet fixedly coupled to a distal portion of the shaft, a second magnet slidingly coupled to the shaft proximal to the first magnet, and a filter including a distal portion coupled to the first magnet and a proximal portion coupled to the second magnet. The first and second magnets are magnetically attracted to each other such that in a radially compressed configuration of the filter, the second magnet is spaced from the first magnet a first distance, and in a radially expanded configuration of the filter, the second magnet slides towards the first magnet such that the second magnet is spaced a second distance from the first magnet, wherein the second distance is smaller than the first distance.

Abstract: A delivery device for percutaneously delivering a stented prosthetic heart valve includes a capsule assembly, a handle, and an outer stability shaft. The capsule assembly includes a capsule and a proximal shaft coupled to the capsule. The capsule includes an expanded configuration wherein the capsule has a first outer diameter, and a collapsed configuration wherein the capsule has a second outer diameter smaller than the first outer diameter. The outer stability shaft defines a lumen and is coupled to the handle and configured to receive the proximal shaft within the lumen of the outer stability shaft. The outer stability shaft has an inner diameter, wherein the first outer diameter of the capsule is greater than the inner diameter of the outer stability shaft and the second outer diameter of the capsule is smaller than the inner diameter of the outer stability shaft.
