    Abstract: The present embodiments provide a stent comprising a plurality of interconnected strut segments that enable expansion of the stent from a delivery state to a deployed state. A first strut segment and a second strut segment, of the plurality of strut segments, each comprise frontal surfaces facing radially inward in the deployed state and rear surfaces facing radially outward in the deployed state. The frontal surface of the first strut segment is at least partially stacked behind the rear surface of the second strut segment in the delivery state. A first barb coupled to at least a portion of the first strut segment. A sharpened tip of the first barb is aligned at least partially circumferentially behind at least one strut segment in the delivery state such that the sharpened tip is not radially exposed.

    Abstract: The present embodiments provide systems and methods for loading a stent or stent graft onto an introducer for intraluminal deployment. In one example, a system includes an endoluminal prosthesis introducer comprising a stent retaining member engageable with a stent end. The system may also include a loading tool for engaging the stent end on the stent retaining member. The loading tool may include a loading body having a passage extending from a first end to a second end and a slot that extends through the tubular loading body from the passage to an outer surface of the tubular loading body, and the slot may further extend from the second end toward the first end. The stent retaining member may be disposed at least partially within the passage of the loading body, and the slot of the loading body may be rotatable around the stent retaining member.

    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.

    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.

    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.

    Abstract: An introducer for an endoluminal prosthesis and a methods for delivering a prosthesis within a body vessel are described. The introducer comprises pusher catheter having a lumen extending therethrough, the lumen being in communication with an opening formed in the sidewall of the pusher. A sheath is disposed over the pusher catheter and also has an opening formed in its sidewall. The sheath is longitudinally movable relative to the pusher catheter between a prosthesis delivery position and a prosthesis deployment position. When the sheath is in the deployment position, the opening formed in the sidewall of the pusher catheter is at least partially longitudinally aligned with the opening formed in the sidewall of the sheath. A wire may extend though the opening in the sheath, the opening in the pusher, through the lumen of the pusher and through a fenestration in a prosthesis to cannulate a branch vessel.

    Abstract: The present invention relates to a deployment handle for a prosthesis delivery device and to a delivery device including such a handle. The handle assembly facilitates the controlled release of a prosthesis from the delivery device, while ensuring that various deployment steps are performed in a particular sequential order. The handle assembly comprises a main handle and a second handle which is rotatably and/or longitudinally moveable relative to the main handle. The second handle has an initial position on the main handle such that it prevents access to, and premature manipulation of, a proximal stent release mechanism, until the stent graft has been at least partially unsheathed.
