A prosthetic heart valve can comprise a stent frame radially movable between a contracted configuration and a maximum expanded configuration. The stent assembly can comprise a plurality of longitudinally extending jack strut assemblies, wherein each jack strut assembly comprises a proximal jack strut comprising a distal surface, a distal jack strut comprising a proximal surface, and a jack screw connecting the proximal jack strut and the distal jack strut. The proximal surface of each distal jack strut does not contact the distal surface of each respective proximal jack strut when the stent assembly is in the contracted configuration. The proximal surface of each distal jack strut contacts the distal surface of each respective proximal jack strut when the stent assembly is in the maximum expanded configuration.

A multiple-firing clip device includes a hollow shaft defining a lateral opening communicating with an environment and a distal shaft portion between the lateral opening and a distal end opening. A shuttle longitudinally moves on the shaft and comprises a shuttle body defining a lumen surrounding the shaft, a snare, and a snare-extender slide defining a snare track to form a snare travel path in which the snare is disposed from the body and through the track and a portion of the body. The slide moves along a given extent defining a slide distance and a distal end and movement of the slide to the distal end shortens the snare travel path to extend the snare portion through the lateral opening, through the distal shaft portion, and distally out from a distal side of the body longer than the given extent to secure a suture with the snare.

A prosthetic heart valve includes a frame, a valve, and an expansion element. The frame is movable between contracted and expanded configurations and includes first struts and second struts non-hingedly coupled together. The second struts are configured to pivot relative to the first struts as the frame moves between the contracted and expanded configurations. The valve is coupled to the frame and includes leaflets. The expansion element extends through a lumen of the first struts. The expansion element is slidable relative to the lumen of the first struts and is configured to move the frame incrementally from the contracted configuration and the expanded configuration and from the expanded configuration to the contracted configuration.

A multiple-firing clip device comprises a shaft comprising an exterior surface, an interior receiving therein suture fixation clips, and a distal end opening shaped to eject a suture fixation clip therefrom. The shaft defines a lateral opening and a distal shaft portion between the lateral opening and the distal end opening. A shuttle moves on the shaft and comprises a shuttle body, a snare having a distal snare portion, and a snare extension slide movable from the shuttle body along a given extent defining a slide distance and a distal end. The shuttle extends at least the distal snare portion distally through the lateral opening from the environment into the interior, through the distal shaft portion, and through the distal end opening along a length that is at least equal to the slide distance when the snare extension slide moves to the distal end of the given extent.

A delivery apparatus can include a handle portion and at least one rotatable drive shaft. The handle portion has an actuation mechanism. The actuation mechanism includes a motor and one or more actuators. The rotatable drive shaft has a proximal end portion and a distal end portion. The proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve. The handle is configured for actuating the actuation mechanism, tracking a response of native tissue when the prosthetic heart valve is in contact with the native tissue, and stopping expansion of the prosthetic heart valve once a rate of change of expansion of the prosthetic heart valve declines below a threshold.

An assembly includes a prosthetic heart valve and a delivery apparatus. The prosthetic heart valve has a plurality of pivotably connected struts and one or more adjustable elements rotatably coupled to the struts. Rotating the adjustable elements in a first direction relative to the struts radially expands the prosthetic heart valve. Rotating the adjustable elements in a second direction relative to the struts radially contracts the prosthetic heart valve. The delivery apparatus includes one or more motors, one or more drive wires coupled to the motors, and a memory. The drive wires are coupled to the adjustable elements of the prosthetic heart valve. The motors are configured to rotate the drive wires and the adjustable elements to expand and contract the prosthetic heart valve. The memory is configured for storing one or more characteristics of the motors, the drive wires, or the prosthetic heart valve.

A method for the hemostasis of perforating and bleeding vessel related to intracerebral hemorrhage (ICH) includes navigating an occlusion device into a parent artery and then deploying the occlusive device to transiently occlude bleeding vessels to reduce blood flow and local blood pressure until hemostasis is achieved, while maintaining flow within the parent artery. Embodiments of the occlusion device include a catheter, an expandable member sized for insertion into the mid-cerebral artery (MCA) and having a length sufficient to occlude at least one ostia of the lenticulostriate arteries (LSA), with a flow path for blood provided from a proximal side of the expandable member to a distal side of the expandable member, and a semi-permeable contacting member about the expandable member and adapted to be in contact with a wall of the MCA adjacent the ostia, the semi-permeable member permitting a reduce flow of blood through the ostia.

A multiple-fire securing device includes a hollow outer shaft, a reloader, a reloader movement assembly, a rail, and securing structures each defining an inner securing orifice. The reloader longitudinally moves within the outer shaft and has a distal end shaped to temporarily contact one of the securing structures. The rail is disposed within the reloader and has an installing location. The securing structures are disposed on the rail. The reloader movement assembly moves the reloader longitudinally in a distal direction to deliver a first securing structure to the installing location from a first proximal position and moves the reloader proximally away from the installing location without the first securing structure to a position in which the distal end of the reloader temporarily contacts a second one of the securing structures. The second and successive securing structures are moved one at a time to the installing location.

A delivery apparatus can include a handle portion and at least one rotatable drive shaft. The handle portion can have an actuation mechanism with a motor. The rotatable drive shaft can have a proximal end portion and a distal end portion. The proximal end portion of the rotatable drive shaft can be coupled to the motor, and the distal end portion of the rotatable drive shaft can be configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism can be configured to control and monitor expansion of the prosthetic heart valve and to control and monitor torque of the motor.

A multiple-firing crimp device comprises crimps, a shaft, a crimp movement assembly, and a snare. Each crimp has an internal hollow. The shaft has a distal crimping location, an exterior surface, and an interior with the clips stacked therein, the crimps moving therein along a longitudinal axis. The shaft defines a lateral opening proximal to the crimping location and communicates the interior to the environment outside the exterior surface. The crimp movement assembly within the shaft delivers the first crimp to the distal crimping location by moving the first crimp longitudinally from a first proximal position into the distal crimping location and returning to a second proximal position without the first crimp. The snare pulls at least one cord from distal of the first crimp through the first crimp and through a portion of the shaft and out the side of the shaft through the lateral opening.

A delivery apparatus comprises a handle portion and at least one rotatable drive shaft. The handle portion has an actuation mechanism and a display. The actuation mechanism includes a motor and one or more actuators. The rotatable drive shaft has a proximal end portion and a distal end portion. The proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve, and the display is configured to display a diameter of the prosthetic heart valve.
