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 graft device having a plurality of axially offset rows of radiopaque markers for rotational orientation of the stent graft device. The stent graft device may include an expandable stent frame and attached graft member. Each row of radiopaque markers may include a plurality of radiopaque markers that are evenly spaced. Each row may also include a length that covers a limited portion of the circumference of the stent graft device, where each row is circumferentially offset such that a fluoroscopic projection of the stent graft device illustrates one of a plurality of unique visual orientations of the axially offset rows for use in visually determining a current rotational orientation of the stent graft device.

Abstract: 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. The auxiliary lumens have an oblong cross-section. 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, the indwelling guide wire can be used to facilitate catheterization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a stent therein.

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: A bifurcated endovascular prosthesis that includes a tubular main body having a diameter, a proximal end, a distal end, an internal lumen extending from the proximal end to the distal end, an anterior side, and a posterior side. The anterior and posterior sides are opposite each other circumferentially around the internal lumen. The prosthesis also includes a first limb that extends from the distal end of the tubular main body along the anterior side of the main body. The first limb has a diameter less than the diameter of the tubular main body and having a proximal end and a distal end. The prosthesis also includes a fenestration adjacent to the proximal end of the first limb. The fenestration extends from the proximal end of the first limb to the posterior side of the tubular main body. The prosthesis also includes a second limb that extends within the internal lumen from the fenestration toward the proximal end of the tubular main body. The fenestration has a substantially diamond shape and a nonlinear profile, and the second limb extends into the lumen along the posterior side of the tubular main body.

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 endograft comprising a proximal end and a distal end is disclosed. The endograft comprises a tube of biocompatible material. The tube comprises: a main lumen extending longitudinally from the proximal end to the distal end, the main lumen including a proximal portion, an intermediate portion and a distal portion; a branch lumen within the intermediate portion of the main lumen; and a seam, the seam extending longitudinally beside both the branch lumen and the distal portion of the main lumen, wherein the tube comprises a lateral cross-section defining a tubular wall pinched together by the seam to form a branch portion.

Abstract: A capsule assembly for an endograft introducer is disclosed. The assembly comprises: a capsule retriever having a plug portion and a tail portion, the plug portion having a lead-in surface, the tail portion having an elongate body extending proximally from the plug portion to an end stop feature receiver; a capsule tube having an end stop feature at a proximal end thereof and terminating in a distal end, the end stop feature and the end stop receiver arranged such that proximal movement of the capsule tube relative to the plug portion is limited; and a capsule cavity inside the capsule tube, a proximal end of a prosthesis being receivable in the cavity. The capsule tube is slidably movable with respect to the capsule retriever to a position in which the distal end of the capsule tube is adjacent to the lead-in surface of the plug portion.

Abstract: A system may include an endoluminal prosthesis and a guide wire. The prosthesis may include a tubular body including a graft material wall, a proximal end opening, a distal end opening, and a lumen extending longitudinally therein. The prosthesis may include first and second fenestrations in the graft material wall. The first and second fenestrations may be spaced from one another circumferentially about the tubular body. The guide wire may have a first end and a second end both extending from a region proximal of the proximal end opening. The guide wire may enter the proximal end opening, exit the first fenestration, partially traverse an exterior surface of the prosthesis, enter the second fenestration, and exit the proximal end opening. No portion of the guide wire may extend distally beyond the distal end opening.

Abstract: 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.
