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 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.

摘要： A delivery device for a collapsible prosthetic heart valve includes a support shaft around which a compartment for the valve is defined, a distal sheath adapted to selectively cover and uncover the compartment and the valve, and a marker cage having a collapsed condition when the distal sheath covers the compartment and an expanded condition when the compartment is uncovered. The marker cage includes at least one rib having a radiopaque marker for determining the positioning of the valve as it is deployed. The valve may be assembled around the marker cage so that the marker cage does not interfere with the radial expansion of the valve during deployment.

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 (10) for an implantable medical device having at least one retention member at an end thereof includes a shaft (24) extending in a longitudinal direction, an elongated sheath (22) surrounding a longitudinal portion of the shaft, a compartment (28) defined inside of the sheath and adapted to receive the medical device in an assembled condition, a retainer (30) positioned at one end of the compartment, and at least one acceptance (36) in the retainer adapted to receive the retention member of the medical device in the assembled condition. The sheath is slidable relative to the shaft in the longitudinal direction to uncover and deploy the medical device. The retainer may be rotatable relative to the shaft to reduce torsional forces in the medical device during delivery and deployment. The retainer may have at least one recess facing the compartment for receiving a strut at an end of a stent of the medical device.

摘要： A delivery system for delivering and deploying a medical implant, such as a prosthetic heart valve, includes an elongated support member, a sheath, and a tip. The sheath is movable relative to the elongated support member between a distal position overlying the medical implant and a proximal position exposing the medical implant for release from the delivery system. The tip is attached to the elongated support member and is positioned at a distal end of the sheath when the sheath is in the distal position. The tip has a compressed condition and an expanded condition, and a maximum diameter in the expanded condition that is larger than the outer diameter of the sheath.
