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: 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: An iliac artery stent graft has a substantially inverted Y shape comprising a second arm terminating in a second end, and first and third arms terminating respectively in a first end and a third end. Each of the arms comprising a tubular graft of biocompatible graft material and the three arms joined being at a junction to allow fluid flow from the second arm into the first and third arms. In use the first end is deployed within the common iliac artery extending towards the external iliac artery, the second end is deployed within the common iliac artery extending towards the iliac bifurcation and the third end is within the common iliac artery and extends towards the internal iliac artery. Each of the three arms are mutually at an angle of approximately 120 degrees to each other. In use the first and second legs form a U shape to allow a deployment device to be smoothly deployed.
