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.

Abstract: Methods for delivering and deploying an endovascular graft to the common and internal iliac arteries are described. A system including a pre-loaded delivery device with a releasably attached extension cannula and an extension sheath for use with such methods is also described.

Abstract: This invention relates generally to an endoluminal prosthesis, and more particularly, to a stent graft assembly and method for treating branched vessels. The assembly includes a first prosthesis, such as an iliac branch device (IBD), comprising a tubular main body, a first leg extending from a distal end of the main body and at least one fenestration formed in the main body. An internal tubular side branch extends proximally from the fenestration into the lumen of the main body, resulting in an iliac branch device having an overall reduced proximal length. The assembly further includes a second prosthesis, or a bridging limb, having a distal end with a scalloped fenestration formed therein to accommodate sealing with the proximal end of the iliac branch device without interfering with the internal branch. A connecting stent graft adapted for placement in the internal iliac artery may be sealingly connected to the internal branch.

Abstract: This invention relates generally to an endoluminal prosthesis, and more particularly, to a stent graft assembly and method for treating branched vessels. The assembly comprises a first prosthesis having an overall shortened length comprising a main body formed of biocompatible graft material having a tapered proximal end. A bifurcated portion extends distally from the main body. The bifurcated portion comprises a first tubular portion defining a first lumen and a second tubular portion defining a second lumen. The assembly further comprises a second prosthesis having a tubular body of biocompatible graft material with a flared distal end portion. The flared distal end portion of the second prosthesis is configured to sealingly engage with the tapered main body of the first prosthesis.

Abstract: The present embodiments provide an endoluminal prosthesis, comprising a prosthetic trunk and a prosthetic branch, each comprising proximal and distal ends and a lumen extending therebetween. The proximal end of the prosthetic branch is secured around an aperture formed in a side surface of the prosthetic trunk. A support structure is coupled to the prosthetic branch. In certain embodiments, a proximal end of the support structure comprises a first width, and a distal end of the support structure comprises a second width, wherein the first width is less than the second width.
