Abstract
A stent-graft delivery system includes an elongate shaft, a tip capture spindle disposed over the shaft, and a distal tip assembly coupled to the distal end of the shaft. At least one component of the delivery system constrains a stent of the stent-graft engaged with the tip capture spindle during delivery and partial-deployment of the stent-graft, and the at least one component is in a threaded relationship with the distal tip assembly. To fully deploy the stent-graft, the elongate shaft, having the distal tip assembly coupled thereto, is rotated to result in longitudinal movement of the at least one component and thereby release the stent from the tip capture spindle. The at least one component that longitudinally moves to fully deploy the stent-graft may be the tip capture spindle and/or a relatively short sleeve that extends over the tip capture spindle to the distal tip assembly.
