摘要：
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.
