Abstract: Delivery devices for delivering a stented prosthesis to a target site are disclosed. Certain disclosed delivery devices include a handle assembly including an actuator, a shaft assembly interconnected to the handle assembly, and are configured to releasably retain the stented prosthesis to the delivery device with at least one elongate tension member. The delivery devices further include a torque shaft that is configured to apply and adjust the amount of tension in the each tension member. For example, the torque shaft can be configured to wind and unwind each elongate tension member around the torque shaft to correspondingly compress and expand the stented prosthesis. The torque shaft can be controlled with an actuator provided in the handle assembly, for example. In some embodiments, the actuator is further configured to axially move the torque shaft.

Abstract: A catheter shaft includes a proximal portion with a first polymer having a first stiffness and a first portion of a tubular braid component extending within the first polymer, an intermediate portion with a second polymer having a second stiffness and a second portion of the tubular braid component extending within the second polymer, and a distal portion with a third polymer having a third stiffness, a third portion of the tubular braid component extending within the third polymer, and a hypotube extending within the third polymer. The hypotube is configured for elastic deformation and includes a sidewall cut with a pattern. Along an overlap segment of the distal portion, the third portion of the tubular braid component and the hypotube overlap each other. The outer shaft is configured for improved torque transmission.

Abstract: A balloon catheter configured for delivery of a prosthetic heart valve is provided. The balloon catheter is configured to deploy a prosthetic heart valve through inflation. The balloon catheter is provided with a reinforcing member configured to increase the rigidity of the balloon catheter over an operational portion of the device. The increased rigidity serves to prevent damage to an introducer sheath, patient anatomy, or the prosthetic heart valve during delivery of the prosthetic heart valve.

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: The disclosure relates to transcatheter stented prosthesis delivery devices including a handle assembly connected to a shaft assembly on which a stented prosthesis is loaded and compressively retained with a plurality of elongate tension members. The delivery devices include a cutting assembly that can sever the elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient. Certain embodiments position the cutting assembly at least within the shaft assembly and others position the cutting assembly over the shaft assembly. Various disclosed cutting assemblies are actuated with the handle assembly or the like, which draw the tension members across the blade or vice versa.
