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.

Abstract: An endoluminal prosthesis system includes a graft having a tubular body with a proximal end and a distal end. A lumen extends from the proximal end to the distal end. A proximal portion of the graft includes the proximal end; a distal portion of the graft includes the distal end; and a middle portion of the graft extends from the proximal portion to the distal portion. A plurality of connection branches are attached to the middle portion. Each of the connection branches has an inner opening at an inner end attached to the middle portion and an outer opening at an outer end disposed radially outwardly from the inner end. Each of the connection branches is pivotable in a proximal and distal direction and a circumferential direction relative to the middle portion. Further, each of the connection branches includes an expandable seal stent at the outer end.

Abstract: An endoluminal prosthesis system for being deployed in a patient's aorta near the heart, includes a graft having a main body with a proximal end configured to be deployed near a patient's heart and a distal end configured to be deployed away from the patient's heart. The main body defines a proximal portion of the graft including the proximal end; a distal portion of the graft including the distal end; a middle portion of the graft extending between the proximal portion and the distal portion. A connection branch attached to the middle portion has an inner end attached to the middle portion and an outer end disposed radially outwardly from the inner end. The outer end of the connection branch includes a terminal ring composed of at least two partial rings pivotable relative to each other and including at least one radially outward barb.

Abstract: The present embodiments provide an endoluminal prosthesis deployment system and method for deploying the prosthesis for cannulation of branch vessels. The prosthesis includes an anterior fenestration and a posterior opening. A guide is disposed to exit the prosthesis lumen through a lateral fenestration, enter through the anterior fenestration, and exit the prosthesis lumen through the posterior opening. A sheath can be preloaded over the branch wire at the lateral fenestration for vessel cannulation, such as in renal arteries. The sheath can include another branch wire that extends from the lateral fenestration to another lateral fenestration. An end of the guide is retracted after partial expansion of the prosthesis, and another sheath is inserted over the retracted guide and moved through the posterior opening and to the anterior fenestration. A separate branch guide wire is then directed through the sheath for vessel cannulation, such as the SMA.

Abstract: A prosthesis delivery device comprises a proximal end and a distal end, a prosthesis retention section at the proximal end, and a prosthesis retained on the prosthesis retention section. The prosthesis has a proximal end releasably attached at the prosthesis retention section and a distal end releasably attached at the prosthesis retention section. A sheath is slidably disposed over the prosthesis. A delivery handle near the distal end the delivery device comprises a rotatable inner cannula having a cannula lumen and cannula handle. The cannula handle is rotatable with the inner cannula. Further, a positioner handle is releasably engaged with the cannula handle. Rotation of the inner cannula releases the proximal end of the prosthesis from the delivery device and withdrawal of the sheath from over the prosthesis releases the distal end of the prosthesis from the delivery device.

Abstract: Disclosed herein is a stent graft device with improved visualization characteristics and a method for making such a device. The device includes a plurality of radiopaque rings and associated structures, which are folded in a predictable fashion prior to crimping. In some embodiments, a mandrel for biasing the end rings of a ringed structure is utilized. In other embodiments, a biodegradable adhesive is used to assist in folding.

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: A method of treatment for a body vessel is provided. The body vessel includes 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 a cutting device or system. 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.
