Abstract:
1. A stent-graft delivery system comprising: an elongate shaft with a distal end for insertion into a vasculature of a patient; a tip capture spindle disposed over the elongate shaft, proximate to the distal end of the elongate shaft, wherein a proximal portion of the tip capture spindle includes a plurality of retainer elements configured to engage a stent of a stent-graft prosthesis and a distal portion of the tip capture spindle includes threads on an outer surface thereof; and a distal tip assembly coupled to the distal end of the elongate shaft, wherein a portion of the distal tip assembly proximally extends over the outer surface of the distal portion of the tip capture spindle and an inner surface of the distal tip assembly includes threads that mate with the threads on the tip capture spindle, and wherein rotation of the elongate shaft rotates the distal tip assembly and results in longitudinal movement of the tip capture spindle.
