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: Methods and apparatuses to place a prosthesis within a receiving structure are provided. A delivery apparatus includes an elongated support member including a support member distal end. A stop cap is disposed at the support member distal end and includes a stop cap transverse dimension larger than an inner diameter of a receiving lumen of the receiving structure. An elongated prosthesis-positioning member extends along the support member and stop cap so a distal surface of the prosthesis-positioning member is disposed at a position longitudinally coincident with a portion of the stop cap. A sheath comprises a sheath lumen receiving the prosthesis-positioning member so the sheath translates longitudinally relative to the prosthesis-positioning member. The delivery apparatus has a loaded configuration in which the prosthesis is received in the sheath lumen with a proximal end of the prosthesis abutting the prosthesis-positioning member distal surface.

Abstract: Systems and methods to place a prosthesis to have a preselected overlap with a receiving structure are provided. In one embodiment, a delivery system may include a primary sheath comprising a primary sheath lumen. The delivery system may further include a secondary sheath comprising a secondary sheath lumen. The primary sheath may be at least partially received within the secondary sheath lumen such that the primary sheath may translate longitudinally within the secondary sheath lumen. The delivery system may further include a prosthesis having proximal and distal ends and being received within the primary sheath lumen adjacent to the primary sheath distal end in a contracted delivery state. The delivery system may further include a length reference mechanism that indicates a length of the primary sheath distal end that extends distal to the secondary sheath distal end during the contracted delivery state of the prosthesis.

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: 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. One or more of the fenestrations may include a branch.

Abstract: An endoluminal prosthesis may include a tubular main graft body including a sidewall and proximal and distal ends. A first stent may be positioned near the proximal end of the main graft body. A second stent may be positioned adjacent to and distal of the first stent. An opening in the sidewall may be positioned longitudinally between a peak of the first stent and a valley of the second stent. A tubular branch may be disposed in the opening. The branch may include first and second end openings. The branch may be flexibly orientable between a retrograde configuration in which the first end opening is oriented toward the distal end and the second end opening is oriented toward the proximal end and an antegrade configuration in which the first end opening is oriented toward the proximal end and the second end opening is oriented toward the distal end.

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 stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.
