A handle assembly for a delivery device the sequential release of trigger wires from a prosthesis to release the prosthesis from the delivery device. The handle assembly has two handles, one of which is a rotating handle. The rotating handle has a first and second trigger wire release mechanisms which operate to sequentially release a first and second trigger wire, respectively, and a locking mechanism. The other handle has a locking mechanism that prevents that operation of the second trigger wire release mechanism until the first trigger wire has been released.

A system for treating a bifurcation includes a first radially expandable stent and a second radially expandable stent. The first stent has a side hole and a plurality of lateral elements extending from the side hole. The second stent has a plurality of axial elements extending away from the proximal end of the second stent. The axial elements of the second stent interdigitate with the lateral elements of the first stent when both stents have been expanded.

An angioplasty apparatus and method including a balloon stent, for facilitating accurate placement of a lumen stent for dilating a stenotic site, the apparatus includes arcuate, low pressure, anchor and/or marker and guide balloon segment(s) connected to a stent deployment catheter at at least one of a proximal and distal end of a wire mesh stent with circumferential gaps in the anchor and/or marker balloon segment or segments to facilitate blood flow and contrast media during a stenting procedure. Optimal positioning of a stent at a stenotic lumen site is facilitated by selective injection of marker fluid into one or more low pressure, anchor and/or marker balloon segment(s).

A positioning anchor is provided for a stent-graft for implantation to treat a damaged body lumen. The positioning anchor is generally tubular surrounding a primary fluid conduit. Arms extend laterally from the generally tubular structure of the anchor surrounding lateral fluid conduits. The form of these arms is preferably custom configured to match a particular patient's luminal geometry. The anchor thus fits within the luminal geometry to remain in a desired fixed position for implantation of the anchor and any stent-graft coupled to the anchor. The anchor is most preferably formed with two walls having a void therebetween which can be filled with fixation media to further secure the anchor at the desired implantation site. A lumen shaper balloon and delivery catheter are also disclosed for proper delivery, expansion and inflation of the positioning anchor and stent-graft elements according to this invention.

An endoluminal prosthesis system deployable in a region of a patient's vasculature having one or more branch vessels, having a main graft body having a first opening in a wall portion of the main graft body and a pre-loaded guidewire positioned inside the main graft body and advanced through the first opening. One or more branch grafts can be attached to the main graft body to cover one or more openings in the main graft body.

An introduction arrangement for a fenestrated or branched stent graft (13) intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer (1) has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator (11) and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath (15) on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter (21) extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire (29) extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

Exemplary embodiments of apparatuses and methods of providing an endovascular′dock within a blood vessel are provided. An apparatus for vascular surgery can be provided, having an external tubular graft capable of expansion and configured to be placed within a sheath in an unexpended state, a first tubular structure provided internally within the external tubular graft and configured for placement of a graft therein, and a second tubular structure provided internally within the external tubular graft and configured for placement of a graft therein. Stent grafts can be provided along each tubular structure to a corresponding blood vessel such that blood flow is provided to the blood vessel from the apparatus within the stent grafts to each blood vessel, blocking the blood flow directly from the aneurysm.
