Abstract: The present disclosure relates to an endoluminal prosthesis, such as a stent graft that includes one or more fenestrations to accommodate endovascular disease, such as an aneurysm in cases where one or more side branches is involved. In one aspect, the prosthesis includes fenestrations that are pivotable to accommodate the dynamic geometry of the aortic branches. In another aspect, the pivotable fenestrations include a first perimeter, a band of flexible material attached and surrounding the first perimeter, a second perimeter attached to and surrounding the band of flexible material and a support frame disposed about a surface of the band of flexible material. The first perimeter, band of flexible material, and second perimeter have a geometric shape. The support frame includes a plurality of support units having curved segments. The curved segments of the support units may be concave with respect to an exterior surface of the prosthesis.

Abstract: A balloon catheter assembly including a catheter, a sleeve, and a balloon. The catheter has a body, an exterior surface, a lumen, a port providing fluid communication between the lumen and the exterior surface, and a coupling mechanism to couple the lumen to an inflation source. The sleeve has an interior surface facing the exterior surface, the sleeve being coaxial with the catheter and configured to move longitudinally about the catheter. The balloon is disposed about the catheter and has a middle segment covering the port, a distal segment coupled to the sleeve, and a proximal segment coupled to the catheter. The middle segment has a middle longitudinal stiffness, the distal segment has a distal longitudinal stiffness, and the proximal segment has a proximal longitudinal stiffness. The middle longitudinal stiffness is greater than the proximal longitudinal stiffness and the middle longitudinal stiffness is greater than the distal longitudinal stiffness.

Abstract: A stent-graft comprises a substantially tubular graft material, and a stent coupled to the graft material. The stent has proximal and distal ends and further has compressed and deployed states. The proximal end is disposed proximally beyond a proximal edge of the graft material, and the distal end has at least one portion overlapping with the proximal edge of the graft material. In one example, the stent comprises at least one distal apex having a bifurcation extending into first and second leg regions. A distal end of the first leg region is positioned to overlap the graft material at a location circumferentially spaced apart from a location at which a distal end of the second leg region overlaps the graft material in the deployed state.

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. Rotation of the cannula causes the portion of the stent to disengage from the coiled member. The end of the coiled member that is secured relative to the cannula is secured using at least two securing members.

Abstract: An endoluminal prosthesis may include a tubular main body and a branch. The main body may include proximal and distal end openings, a lumen, a sidewall, and a fenestration in the sidewall. The branch may include a tubular retrograde branch segment, a tubular antegrade branch segment, and a tubular branch junction. The retrograde branch segment may include an inlet opening fluidly coupled to the fenestration of the main body and an outlet opening fluidly coupled to the branch junction and positioned longitudinally between the proximal end opening and the fenestration of the main body. The antegrade branch segment may include an inlet opening fluidly coupled to the branch junction and an outlet opening positioned longitudinally distal of the inlet opening of the antegrade branch segment. The retrograde branch segment and the antegrade branch segment may be in fluid communication with one another through the branch junction.
