Systems and methods for deploying a portion of a stent using at least one coiled member
First Claim
1. A method for deploying at least a portion of a stent, the method comprising:
- introducing a cannula having an outer surface, and further introducing at least one coiled member having proximal and distal ends, wherein one of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula;
introducing a stent, wherein a portion of the stent is disposed around the end of the coiled member that is unsecured relative to the outer surface of the cannula; and
rotating the cannula to cause the coiled member to rotate and thereby disengage the portion of the stent from the coiled member,wherein first and second coiled members are longitudinally spaced apart from one another along a length of the cannula, the method comprising rotating the cannula to cause a first stent portion to disengage from the first coiled member and rotating the cannula to cause a second stent portion to disengage from the second coiled member.

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 at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member.

6. A method for deploying at least a portion of a stent, the method comprising:
-
introducing a cannula having an outer surface, and further introducing at least one coiled member having proximal and distal ends, wherein one of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula; introducing a stent in a position being disposed over the cannula, wherein a portion of the stent is disposed around the end of the coiled member that is unsecured relative to the outer surface of the cannula; and rotating the cannula to cause the coiled member to rotate and thereby disengage the portion of the stent from the coiled member. - View Dependent Claims (7, 8, 9, 10, 11)
