20110307048 | PRE-LOADED MULTIPORT DELIVERY DEVICE - A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. Indwelling access sheaths are provided within auxiliary lumens of a pusher catheter and dilators are preloaded into the access sheaths along with the indwelling guide wire. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate cathertisation of a side branch or target vessel through the fenestration or be used to stabilise the access sheath during catheterisation, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath. | 12-15-2011 |
20120035714 | Stent Graft Having A Marker And A Reinforcing And Marker Ring - A reinforcing and marker ring for a stent graft is disclosed. The reinforcing and marker ring comprises a plurality of turns of a substantially inextensible resilient wire in a circular shape and terminal ends at each end of the wire. The terminal ends each comprise a loop, each loop attachable to a stent graft having an opening or a fenestration so as to substantially lock a peripheral length of the circular shape. A marker winding is wound helically around the reinforcing wire, the marker winding being viewable on an image display system employing electromagnetic radiation so as to indicate the location of a periphery of the fenestration. The circular shape of the resilient wire, with the marker winding wound around it, is collapsible under radial pressure to form a squashed circular shape for loading into a delivery device, the squashed circular shape self-expandable back to a substantially circular shape upon release from the delivery device. The marker winding defines a curved passageway around the resilient wire of the reinforcing ring, the curved passageway having an internal diameter D, wherein the marker winding is helically wound with a pitch providing at least one winding per length D along the reinforcing wire of the reinforcing ring. The marker winding may be a radiopaque gold wire wound around a nitinol reinforcing wire. | 02-09-2012 |

20130297001 | STENT GRAFT ADAPTOR - A stent graft adaptor has an outer graft tube and an inner graft tube with the inner graft tube substantially concentric with and within the outer graft tube. A joining member extends between the inner tube and the outer tube. The s joining member can be a continuous fold of graft material extending from a proximal end of the outer tube to a proximal end of the inner tube. The inner tube has at least one self expanding stent on an outer surface thereof and the outer graft tube has at least one self expanding stent on an inner surface. The outer surface of the outer tube provides a sealing surface to engage against the wall of a vessel and the inner tube provides a sealing surface to engage with a corresponding sealing surface of a stent graft deployed through it. The outer sealing surface can include barbs. | 11-07-2013 |

20150018932 | ILIAC STENT GRAFT - 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. | 01-15-2015 |

The wall of the stent graft in the vicinity of the side arm has a loose fold of the graft material and the side arm is fastened to the loose fold of graft material. The tubular side arm has an inner end and an outer end and is fastened into the loose fold of graft material by a circumferential fastening around the tubular side arm between the inner end and the outer end so that the tubular side arm extends partially within the tubular body of the stent graft and partially outside the tubular body of the stent graft. The loose fold of graft material can be formed by the graft material defining a recess in the wall of the stent graft. To enable movement or angulation proximally and distally and from side to side the loose fold of graft material is provided both proximally and distally of the tubular side arm and circumferentially to each side of the tubular side arm. | 12-22-2011 |
