1. A system for deploying at least a portion of a stent, the system comprising:
- a cannula having an outer surface;
an auger having proximal and distal ends and a plurality of turns disposed therebetween, where the auger is coupled to the outer surface of the cannula;
a stent having a portion dimensioned to be disposed within a valley of the auger, where rotation of the cannula and the auger advances the portion of the stent in a predetermined longitudinal direction;
an enclosure encircling the auger, where the enclosure has a first end having a first outside dimeter and a second end having a second outside diameter, where the first outside diameter is larger than the second outside diameter,where the first end of the enclosure is proximal to the second end of the enclosure, andwhere the enclosure comprises a plurality of struts separated by a plurality of slots, where the portion of the stent extends through one of the plurality of slots in a delivery state.

Abstract
The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and an auger having a plurality of turns coupled to the outer surface of the cannula. A stent has a portion dimensioned to be disposed within a valley of the auger. Rotation of the cannula and the auger advances the portion of the stent in a predetermined longitudinal direction.
