摘要:
A stent or stent-graft delivery system includes a handle having a graft cover retractor having a screw gear and a drive and quick release assembly. The drive and quick release assembly includes a proximal portion and a distal portion that are separable. The proximal portion of the drive and quick release assembly rotates in a first rotational direction about the screw gear to retract the graft cover using the screw gear. The drive and quick release assembly transitions from retraction using the engagement with the screw gear to retraction by sliding by the user grasping the distal portion instead of the proximal portion, and sliding the proximal portion only along the screw gear. In transitioning from using the screw gear to sliding along screw gear, it unnecessary to push any button and unnecessary for the user to remove her/his hand from the assembly.
