SYSTEM FOR DEPLOYING AT LEAST A PORTION OF A STENT

摘要

The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula (30) having an outer surface (31), and at least one coiled member (40) having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member (40) is secured to the outer surface (31) of the cannula (30), and the other of the proximal and distal ends of the coiled member (40) is unsecured relative to the outer surface (31) of the cannula (30). A portion of a stent is looped around the unsecured end of the coiled member (40). Rotation of the cannula (30) causes the portion of the stent to disengage from the coiled member (40). The end of the coiled member (40) that is secured relative to the cannula (30) is secured using at least two securing members.
