Abstract: A stent graft adaptor has an outer graft tube and an inner graft tube with the inner graft tube substantially concentric with and within the outer graft tube. A joining member extends between the inner tube and the outer tube. The s joining member can be a continuous fold of graft material extending from a proximal end of the outer tube to a proximal end of the inner tube. The inner tube has at least one self expanding stent on an outer surface thereof and the outer graft tube has at least one self expanding stent on an inner surface. The outer surface of the outer tube provides a sealing surface to engage against the wall of a vessel and the inner tube provides a sealing surface to engage with a corresponding sealing surface of a stent graft deployed through it. The outer sealing surface can include barbs.

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: The present embodiments provide a medical device for implantation in a patient comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

Abstract: A stent graft having an internal bidirectional branch formed from a tubular segment of graft material. The internal bidirectional branch extends within the lumen of the stent graft and proximally and distally from a lateral opening in the sidewall of the stent graft. The tubular segment from which the stent graft is made is partitioned into first and second sections along a length of the tubular segment to form the internal bidirectional branch. The lateral opening has a length and a width that may be greater than the diameter of the internal bidirectional branch and may be in the shape of a quadrilateral. The internal bidirectional branch and the stent graft are formed from a single piece of graft material.

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.

Abstract: A deployment device for deploying an expandable endoluminal prosthesis within a body vessel may include an elongate member extending longitudinally along at least a portion of a length of the deployment device. The deployment device may include at least one engagement member coupled to the elongate member and extending outwardly from the elongate member. The deployment device may include a circumferential trigger wire extending at least partially circumferentially around the elongate member and removably received between the engagement member and the elongate member. The circumferential trigger wire may be manipulatable from a distal end of the deployment device, whereby the circumferential trigger wire is removable from between the engagement member and the elongate member.

Abstract: A method of making an internal bidirectional branch and an endoluminal prosthesis from a tubular segment of graft material. The tubular segment is partitioned into first and second sections along a length of the tubular segment. The first section has a width less than a width of the tubular segment, and the second section has a width less than the first section. The second section is partitioned into at least three sub-sections. The tubular segment is connected along a lateral edge of the first and third sub-sections of the second section. The tubular segment is turned inside out such that the bidirectional branch is positioned within a lumen of the first section and an opening of the second sub-section is exposed.

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.
