Abstract: An endoluminal prosthesis with a main tubular body and an auxiliary body surrounding the main tubular body to create a cavity between the main tubular body and the auxiliary body. At least one dividing wall attached to the main tubular body and the auxiliary body divides the cavity into at least two chambers, one of which has an outlet opening to the exterior of the prosthesis. Each chamber is in fluid communication with the main tubular body through fenestrations in the main tubular body and with each other.

Abstract: A prosthesis delivery device comprises a proximal end and a distal end, a prosthesis retention section at the proximal end, and a prosthesis retained on the prosthesis retention section. The prosthesis has a proximal end releasably attached at the prosthesis retention section and a distal end releasably attached at the prosthesis retention section. A sheath is slidably disposed over the prosthesis. A delivery handle near the distal end the delivery device comprises a rotatable inner cannula having a cannula lumen and cannula handle. The cannula handle is rotatable with the inner cannula. Further, a positioner handle is releasably engaged with the cannula handle. Rotation of the inner cannula releases the proximal end of the prosthesis from the delivery device and withdrawal of the sheath from over the prosthesis releases the distal end of the prosthesis from the delivery device.

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 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: 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: An endoluminal prosthesis introducer may include a rotatable inner cannula including a proximal end. The introducer may include a proximal tip disposed at the proximal end of the inner cannula and including a distal end. The introducer may include a retaining member including an engaging member extending radially outward. The retaining member may be disposed about the proximal end of the inner cannula. In response to rotation of the inner cannula with respect to the retaining member, the proximal tip may be longitudinally movable relative to the engaging member between a retaining configuration and a releasing configuration. The proximal tip and the engaging member may be spaced from one another by a greater longitudinal distance in the releasing configuration than in the retaining configuration.

Abstract: A prosthesis delivery device having a cannula with an expandable positioning device disposed at the proximal end thereof is disclosed. A prosthesis is retained on the cannula distal of the expandable device. Expansion of the expandable device retains and centers the delivery device and the prosthesis carried thereon in the vessel and allows repositioning of the prosthesis without contacting the proximal end of the prosthesis with the vessel walls prior to deployment.
