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elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient.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.

Transcatheter prosthetic heart valve delivery system with distal cutting assembly

Embodiments hereof relate methods of delivering a valve prosthesis to an annulus of a native valve of a heart. A valve delivery system is introduced into a ventricle of the heart via a ventricular wall of the heart. The valve delivery system has a displacement component at the distal portion thereof. The valve prosthesis is in a delivery configuration and the displacement component is in a delivery state in which the displacement component has a first outer diameter. While the valve prosthesis is in the delivery configuration, the displacement component of the valve delivery system is radially expanded into an expanded state in which the displacement component has a second outer diameter greater than the first outer diameter. The valve delivery system is advanced towards the annulus of the native valve of the heart with the displacement component in the expanded state to displace chordae tendineae.

Valve delivery system having an integral displacement component for managing chordae tendineae in situ and methods of use thereof

Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a covering feature associated with the spindle for selectively covering at least a portion of a stented prosthetic heart valve tethered to the spindle in a delivery state. In some embodiments, the covering feature includes a tip mounted to the spindle. The tip can include an overhang region for selectively covering a portion of the stented prosthetic heart valve. In other embodiments, the tip can include a tip body and a compressible foam bumper. In yet other embodiments, the covering feature includes an outer sheath arranged to selectively cover the stented prosthetic heart valve. The outer sheath can be elastic and stretchable for recapturing a partially expanded prosthesis, for example by including one or more windows covered by a stretchable covering layer.

Transcatheter prosthetic heart valve delivery system with protective feature

Delivery devices and methods for delivering a stented prosthesis to a target site are disclosed. Disclosed delivery devices include a handle assembly including an actuator, an inner 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 tension management device that is configured to limit the amount of tension that can be applied via the actuator to the at least one tension member. Certain embodiments are configured to apply different tension limits to different tension members that are controlled by a one or more actuators. Other various embodiments include one or more tension adjustors to selectively adjust one or more tension limits.

Tension management devices for stented prosthesis delivery device

A delivery device for percutaneously delivering a stented prosthetic heart includes a sheath, a handle, and adjustment device including a fine adjustment mechanism, and an outer stability shaft. The sheath defines a lumen and is configured to compressively constrain the stented prosthetic heart valve. The handle is coupled to the proximal portion of the sheath and includes an actuator mechanism coupled to a proximal portion of the sheath that is configured to selectively move the sheath relative to the housing to release the stented prosthetic heat valve. The adjustment device is coupled to the handle and includes an adjustment lumen through which the sheath and the handle slidably extend. The outer stability shaft is coupled to the adjustment device. The fine adjustment mechanism is configured to selectively move the handle and the sheath relative to the adjustment device and the outer stability shaft.

Delivery device for prosthetic heart valve with capsule adjustment device

Delivery devices for delivering a stented prosthesis to a target site are disclosed. Disclosed delivery devices include a handle assembly including an actuator, an inner 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 tension management device that is configured to limit the amount of tension that can be applied via the actuator to the at least one tension member. Certain embodiments are configured to apply different tension limits to different tension members that are controlled by a one or more actuators. Other various embodiments include one or more tension adjustors to selectively adjust one or more tension limits.
