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.

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 crimping tool for use with a collapsible prosthetic valve having a stent frame with a plurality of cell openings, and a valve structure assembled in the stent frame. The crimping tool includes a plurality of resilient tines defining an array around a longitudinal axis of the crimping tool. The array has a first cross-section in an expanded state and a second cross-section less than the first cross-section in a collapsed state. The plurality of tines are adapted to intersect the plurality of cell openings in an assembled position of the crimping tool on the prosthetic valve to prevent pinching of the valve structure by the stent frame as the prosthetic valve is collapsed.
