Systems and methods for deploying a portion of a stent using at least one coiled member

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 having an outer surface, and a coiled member having proximal and distal ends and a plurality of turns disposed therebetween. At least a portion of the coiled member is secured to the outer surface of the cannula. A stent is releasably secured to a portion of the coiled member. A protective cage may encircle the coiled member.

主权项

1. A system for deploying at least a portion of a stent, the system comprising:
a cannula having an outer surface; a coiled member having proximal and distal ends, where at least a portion of the coiled member is secured to the outer surface of the cannula; a stent that is releasably secured to a portion of the coiled member; and a protective cage encircling the coiled member, where the protective cage comprises a plurality of struts separated by a plurality of slots, where a portion of the stent that is releasably secured to the coiled member extends through one of the plurality of slots in a delivery state, and where at least one of the plurality of slots has proximal and distal regions and a width at the proximal region is greater than a width at the distal regions.
