| 摘要 |
The present invention generally relates to medical devices, particularly to a SDS (stent delivery system) that incorporates a spring stent stop. The delivery system, owing to a novel stent stop construction, can be assembled, with the crimped stent in place within the outer sheath of the device, to enable the device to be assembled with considerably greater efficiency by eliminating processes and component(s). In one embodiment, a spring stent stop comprises a plurality of elements arranged to define a through hole sized to receive the inner shaft of the medical implant delivery device, the elements distally projecting from a first proximal end, which elements are radially compressible inward towards the inner shaft member, yet biased to project radial openness at the distal end of the spring stent stop, which radial openness at the distal end is relatively greater than the radial openness of the proximal end of the device wherein the spring stent stop is adapted to be affixed to an inner shaft member of the medical implant delivery device. |
