| 摘要 |
A system for delivering a medical implant includes an expandable member at least partially positioned inside the medical implant and operable to radially expand at least a portion of the medical implant to an expanded condition, first and second grasping mechanisms each adapted to grasp a portion of the medical implant, and a displacement mechanism operatively coupled to the first and second grasping mechanisms and configured to move the first and second grasping mechanisms between an inner position in which the first and second grasping mechanisms are relatively close to one another, and an outer position in which the first and second grasping mechanisms are relatively distant to one another. The movement of the first and second grasping mechanisms from the outer position to the inner position at least partially collapses the medical implant from the expanded condition to enable the medical implant to be repositioned if necessary.
