Abstract: An endoluminal graft includes a tubular graft material having a closed sleeve integral with the tubular graft material. The closed sleeve extends a distance along the tubular graft material. A length of wire extends at least partially along the distance and is enclosed by the sleeve. The tubular graft material and the sleeve may comprise a single piece of graft material. The sleeve may be a closed circumferential sleeve and/or a closed longitudinal sleeve.

Abstract: Examples of prostheses are provided having an internal branch. A tubular graft body of the prosthesis defines a main lumen extending between an inflow end and an outflow end of the graft body. A stent structure is coupled along the graft body. A trough is at least partially defined by a trough wall extending into the main lumen from a sidewall of the graft body. A side branch defines a branch lumen and extends from the trough within the main lumen towards one of the inflow or outflow ends of the graft body. A branch lumen facing surface of the trough wall is a continuous surface with an outer surface of the sidewall of the graft body. A boundary of the trough may be configured to provide a smooth transition surface between the trough and the sidewall.

Abstract: A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, the plurality of cells defining an elongated tube with a lumen running therethrough. The elongated tube has first, second, and third sections, the first section having a substantially first diameter and the third section having a substantially constant second diameter that is larger than the substantially constant first diameter of the first section, wherein the diameter of the second section transitions from the first diameter to the second diameter. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second and third sections. In the second section, the plurality of intersecting elongated members includes a plurality of pairs of elongated members, wherein each pair of elongated members includes two adjacent elongated members twisted axially around each other.

Abstract: A method and system for treatment for a body vessel having a dissection flap formed from a wall of the body vessel, which longitudinally separates a natural body vessel lumen into a true lumen and a false lumen. One or more cuts are formed in the dissection flap with the cutting device or system including cutting blades. An expandable device is inserted within the true lumen, and expanded to reappose the dissection flap against the wall of the body vessel where the dissection flap was detached from the wall such that the false lumen is closed. A variety of cut patterns are disclosed.

Abstract: Methods of reducing air within a stent graft delivery device are disclosed, utilizing various flushing techniques. A port in a manifold that includes a pusher catheter coaxially disposed about a guide wire catheter is flushed. A portion in a sheath hub that excludes a longitudinally extended outer sheath coaxially disposed about the pusher catheter is flushed with a flushing fluid and/or a blood soluble gas, such as carbon dioxide. The guide wire catheter is also flushed.

A first handle extends proximally from the main handle and is rotationally moveable relative to the main handle, the first handle having a proximal end and a distal end and defining a first handle interior. A second handle extends distally from the main handle and is rotationally moveable relative to the main handle, the second handle having a proximal end and a distal end and defining a second handle interior. The first handle comprises a threaded internal surface extending between the proximal and distal ends and the second handle comprises a threaded internal surface extending between the proximal and distal ends.

Abstract: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.
