摘要： A delivery device (10) for an implantable medical device includes an inner shaft (26) extending in a longitudinal direction and defining a compartment (23) adapted to receive the medical device in an assembled condition, an outer shaft (22) surrounding a longitudinal portion of the inner shaft, and a distal sheath (24) operatively attached to the outer shaft (22). The distal sheath (24) is slidable between a first position enclosing the compartment (23) and a second position exposing the compartment (23) for deployment of the medical device. A sleeve 30 surrounds at least a longitudinal portion of the outer shaft (22) and provides a substantially blood tight bearing surface that facilitates sliding movement of the delivery device (10) in an introducer (2).

摘要： An assembly for collapsing a self-expanding prosthetic heart valve includes a compression member, a support member and a constricting member. The compression member has a tapered wall between its first open end and its second open end, the tapered wall defining an open space adapted to receive the valve. The support member has a base and a recess adapted to receive an end of the valve. The support member and the compression member are movable toward one another to compress the valve and push it through a relatively small aperture in the second open end of the compression member. The second end of the constricting member is sized to receive the compressed valve from the second open end of the compression member for loading into a delivery device.

摘要： A delivery device for a collapsible heart valve includes an operating handle, including a frame defining a movement space therein, a carriage assembly moveable within the movement space, and a first resheathing lock having a locked position and an unlocked position. The delivery device further includes a catheter assembly, including a first shaft around which a valve-receiving compartment is defined, the first shaft being fixedly connected to one of the frame or the carriage assembly, and a distal sheath operatively connected to the carriage assembly. The distal sheath is moveable between a closed condition adapted to maintain the valve in the compartment and an open condition adapted to fully deploy the valve. With the resheathing lock in the locked position, the distal sheath is unable to move to the open condition to fully deploy the valve.

摘要： A delivery device (100) includes a support member (128), a distal sheath (130), an outer shaft (120) and a strengthening member (140). The support member is adapted to hold a prosthetic heart valve. The distal sheath is slidable relative to the support member between a first position in which the distal sheath is adapted to maintain the prosthetic heart valve in a collapsed condition, and a second position in which the distal sheath is adapted to expose the prosthetic heart valve. The outer shaft is connected to the distal sheath and has a curved portion (134). The straightening member is slidable on the outer shaft between a proximal position in which the straightening member does not cover the curved portion of the outer shaft, and a distal position in which the straightening member covers and substantially straightens at least a portion of the curved portion of the outer shaft.

摘要： A delivery system for delivering a collapsible prosthetic heart valve includes a valve support structure for supporting a collapsible prosthetic heart valve, and a distal sheath movable in a longitudinal direction relative to the valve support structure between a first position in which the distal sheath is adapted to surround a collapsible prosthetic heart valve supported on the valve support structure, and a second position in which the distal sheath is adapted to expose the collapsible prosthetic heart valve for deployment. The distal sheath is at least partially formed of an inner polymer layer, an outer polymer layer, and a tubular supporting member sandwiched between the inner polymer layer and the outer polymer layer.
