    Abstract: Methods and apparatuses to place a prosthesis within a receiving structure are provided. A delivery apparatus includes an elongated support member including a support member distal end. A stop cap is disposed at the support member distal end and includes a stop cap transverse dimension larger than an inner diameter of a receiving lumen of the receiving structure. An elongated prosthesis-positioning member extends along the support member and stop cap so a distal surface of the prosthesis-positioning member is disposed at a position longitudinally coincident with a portion of the stop cap. A sheath comprises a sheath lumen receiving the prosthesis-positioning member so the sheath translates longitudinally relative to the prosthesis-positioning member. The delivery apparatus has a loaded configuration in which the prosthesis is received in the sheath lumen with a proximal end of the prosthesis abutting the prosthesis-positioning member distal surface.

    Abstract: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.

    Abstract: A first endoluminal prosthesis coupled to an inner catheter and a dilator tip is delivered to the body vessel via a guidewire and a delivery sheath in a conventional manner. After deployment of the first endoluminal prosthesis at the target site, the dilator and catheter are retracted from the body, leaving the delivery sheath in place. A second endoluminal prosthesis is housed within a peel-away sheath without a catheter or dilator tip, and is mated to the delivery sheath outside the patient. The second prosthesis is advanced from the peel-away sheath into the delivery sheath without the use of a dilator tip or catheter. As the second prosthesis is advanced into the delivery sheath from the peel-away sheath, the peel-away sheath is peeled away. The second prosthesis is advanced through the delivery sheath and delivered into an overlapping engagement with the first prosthesis.

    Abstract: An endoluminal prosthesis includes an expandable stent graft that includes a cannula extending through a lumen of the stent graft. A suture is threaded along the perimeter of the graft through openings therein, with an inner end of the suture mounted to the cannula. The cannula is rotatable relative to the graft to wind or unwind the suture around the cannula and cause the graft to become compressed when wound or allow the graft to expand when unwound. The cannula includes an attachment member for retaining an inner end of the suture, and the attachment member can release the inner end of the suture when adjustment of the graft diameter is no longer desired.

    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, and a second perimeter attached to and surrounding the band of flexible material. The first perimeter, band of flexible material, and second perimeter have a geometric shape. In one aspect, the prosthesis includes at least three pivotable fenestrations.

    Abstract: A delivery device and methods for deploying an endovascular prosthesis within the common and internal iliac arteries are described. The device comprises a pusher catheter having a proximal end and a pusher extension extending proximally therefrom. A tubular prosthesis having a side branch is releasably coupled to the pusher extension. An extension dilator extends proximally from the proximal end of the pusher catheter, extends at least partially along an external surface of the main tubular body, into a distal end of the side branch and exits a proximal end of the tubular prosthesis. The extension dilator can be tracked over a guide wire which serves to both position the device within a vessel and also to facilitate cannulation of an internal iliac artery.
