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.
Claims20
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.
A method for deploying at least a portion of a stent, the method comprising:
- providing a cannula having an outer surface, and an auger having a plurality of turns coupled to the outer surface of the cannula;
- positioning a portion of a stent within a valley of the auger in a delivery state;
- and
- rotating the cannula and the auger advance to advance the portion of the stent in a predetermined longitudinal direction.
