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 occlusion device comprising a plurality of expandable hydrophilic foam elements is described. When the device is deployed to a body vessel or a body cavity, it expands radially due to uptake of liquid from the body fluids with which it is in contact. The device may optionally have a surrounding meshwork, an inner spring, and a screw-type deployment mechanism. A method of deploying the device is also provided.

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: An expandable endoluminal prosthesis may include a graft body and a support structure attached to the graft body. The graft body may include a tubular body of nonwoven electrospun fibers disposed about a longitudinal axis. A first fiber matrix segment may be attached to and extend in a transverse direction along the tubular body. A second fiber matrix segment may be attached to and extend in a longitudinal direction along the tubular body.

Abstract: The present embodiments provide systems and methods for facilitating deployment of a stent. In one embodiment, the system comprises an inner cannula, and at least one trigger wire extends at least partially within a lumen of the inner cannula and has an exposed portion extending radially outside of the lumen of the inner cannula. The exposed portion of the at least one trigger wire engages an associated portion of a stent in a delivery state. An outer cannula is sized for longitudinal movement over a portion of the inner cannula. Selective distal retraction of the outer cannula permits partial deployment of the stent to an extent of slack provided by the at least one trigger wire, and selective proximal advancement of the outer cannula incrementally urges the exposed portion of the at least one trigger wire radially inward to constrain the associated portion of the stent.

Abstract: An endoluminal prosthesis that includes a support structure having a plurality of struts and an anchor that is attachable to the support structure. The anchor includes an anchor body and one or more barbs extending outwardly from the anchor body. The anchor body includes a cannula having a first end, a second end, and a middle section. The middle section includes a plurality of open portions arranged in a plurality of arrays around the anchor body.
