Abstract
The present embodiments provide systems and methods for deploying at least a portion of a stent, comprising a retaining member having a main body. At least one slot is formed into the main body. The at least one slot comprises a circumferentially enclosed segment and an axial opening. A portion of a stent is restrained from moving radially outward when disposed within the circumferentially enclosed segment, and the portion of the stent is self-expandable radially outward when aligned with the axial opening.
Claims20
A system for deploying at least a portion of a stent, the system comprising:
- a retaining member comprising a main body having first and second ends;
- at least one slot formed into the main body, the at least one slot comprising a circumferentially enclosed segment and an axial opening;
- and
- a stent comprising a portion having a first width that is less than a second width of the axial opening of the retaining member,
- where the stent is restrained from moving radially outward when disposed within the circumferentially enclosed segment, and where the portion of the stent is self-expandable radially outward when aligned with the axial opening.
A method for deploying at least a portion of a stent, the method comprising:
- providing a retaining member comprising a main body having first and second ends, and at least one slot formed into the main body, the at least one slot comprising a circumferentially enclosed segment and an axial opening;
- positioning a portion of a stent within the axial opening of the retaining member, and subsequently within the circumferentially enclosed segment, thereby radially restraining the portion of the stent in a compressed state;
- and
- rotating the retaining member relative to the stent, thereby aligning the portion of the stent with the axial opening and permitting the stent to self-expand radially outward.
A system for deploying at least a portion of a stent, the system comprising:
- an inner cannula;
- an outer cannula that is longitudinally movable with respect to the inner cannula;
- a retaining member comprising a main body having proximal and distal ends, where at least a portion of the retaining member is secured to an outer surface of the outer cannula;
- an atraumatic tip coupled to the inner cannula at a location distal to the retaining member;
- and
- a stent that is removably coupled to the retaining member by rotating the outer cannula and the retaining member relative to the stent,
- where at least a portion of the stent is disposed proximally beyond the proximal end of the retaining member and distal to the atraumatic tip.
