摘要： 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.

摘要： The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. A trigger wire is adapted to be coupled to at least one of the proximal apices to restrain a proximal end of the stent during delivery. In a first embodiment, a first proximal apex comprises a bore for receiving the trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. The trigger wire therefore is only coupled to selected ones of the proximal apices. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

摘要： Disclosed is a stent graft prosthesis comprising a graft portion that includes a main body portion and an cuff portion, the cuff portion generally located at or near the proximal end of the main body portion and extending circumferentially therealong. Stents comprising the graft supporting structure are also attached to graft portion about the proximal end. In one embodiment, the cuff portion comprises material that is folded over the outside surface of the main body portion with an anchoring stent being attached over the cuff and main body portions, extending proximally therefrom. In another series of embodiments, the cuff portion comprises an external sealing zone that extends around the outer main body portion to help prevent leakage of fluids. In one example, the material of the second edge of the cuff portion is frayed to better engage the vessel walls and promote thrombus and/or tissue growth.

摘要： A method of assembling of a stent graft (20) including temporarily diameter reduction arrangements to enable partial release of a stent graft to assist with positioning before complete release. The diameter reduction arrangement includes a release wire (72) and flexible threads (74, 80) extending to struts (76) of a self expanding stent (70) either side of the release wire and being pulled tight. Removal of the release wire enables full expansion of the self expanding stent.

摘要： An emergency transection intervention device has an elongated catheter (4) with a movable nose cone dilator (8) temporarily closing off the first end of the elongate catheter, a haemostatic seal (6) on a second end of the catheter and closing off the second end of the elongate catheter. First and second inflatable balloons (12, 14) are spaced apart on the elongate catheter, and there is an aperture (16) in the elongate catheter between the balloons and the haemostatic seal. The emergency transection intervention device can be deployed into a blood vessel of the human or animal body, during an emergency procedure for instance, with the balloons positioned either side of a damaged portion of the vessel and the balloons inflated such that a region of the vessel between the balloons is isolated. The nose cone dilator can then be advanced to allow blood flow through the elongate catheter and exit through the aperture in the elongate catheter to bypass the damaged portion of the vessel during repair.

摘要： A stent graft introducer (1) which includes a handle arrangement which by telescopic movement of a slide or slide portions (104, 106) into a handle portion (100) causes controlled sequential deployment of a stent graft (14). Stops (218, 217, 218, 219) ensure actions are carried out in a selected order. A sheath (116) of the introducer is fixed to a slide portion such that with retraction of the slide portion the sheath is withdrawn from a stent graft retained on the introducer and at a selected position trigger wires retaining the stent graft onto the introducer are also released. Interconnections between the slides and the handle are provided to prevent relative rotation and re-extension after full retraction.

摘要： An introducer assembly for accessing a target site in the anatomy of a patient includes a sheath having a proximal end and a distal end, and having a lumen extending therethrough. At least a portion of the sheath distal end has a curved configuration. A tapered dilator has a proximal end and a distal end, and is sized to be received in the sheath lumen. The dilator has a length such that at least a distal tip portion of the dilator extends beyond the distal end of the sheath when the dilator is received in the sheath lumen. The dilator may be formed of polyurethane, and has a stiffness not exceeding a stiffness of the sheath curved portion such that the sheath substantially maintains the curved configuration when the dilator is received in the sheath lumen.
