Abstract: The present embodiments provide systems and methods for deploying at least a portion of a stent. In one embodiment, the system comprises a cannula having an outer surface, and at least one coiled member having proximal and distal ends and a plurality of turns disposed therebetween. One of the proximal and distal ends of the coiled member is secured to the outer surface of the cannula, and the other of the proximal and distal ends of the coiled member is unsecured relative to the outer surface of the cannula. A portion of a stent is looped around the unsecured end of the coiled member and disposed within spacing between adjacent turns of the coiled member. Rotation of the cannula subsequently causes the portion of the stent to disengage from the coiled member.

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.

Abstract: A method of making a contoured internal limb including providing a flattened tubular segment of graft material, and a prosthesis including the contoured internal limb. The tubular segment includes a left lateral edge, a right lateral edge, a first length extending from the left lateral edge to the right lateral edge, and a second length extending from a proximal end to a distal end of the tubular segment. The method also includes contouring a proximal portion, a middle portion, and a distal portion of the contoured internal limb from the tubular segment. The method also includes closing a right lateral edge of the proximal portion and a right lateral edge of a first section of the middle portion. The method further includes removing the proximal, middle and distal portions of the contoured internal limb from the tubular segment and maintaining a second section of the middle portion as circumferentially continuous.

Abstract: An endoluminal prosthesis system may include a main graft and an extension graft. The main graft may include a tubular main body having a sidewall, open proximal and distal ends, a lumen, and a fenestration in the sidewall. The extension graft may include a tubular extension body, and tubular first and second extension legs. Each of the first and second extension legs may extend from the extension body and include a lumen in fluid communication with the extension body lumen. The extension graft may be deployable within the main graft such that the extension body extends through the fenestration in the sidewall of the main body. Each of the first and second extension legs may extend outward away from the main graft. An auxiliary guide such as an auxiliary cannula and/or auxiliary guide wire may be preloaded in the extension graft and extend through the lumen of each of the second extension leg and the extension body.

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: 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.

A wire segment may include a proximal portion positioned proximal of the proximal end opening and a distal portion positioned distal of the distal end opening. The wire segment extend through the fenestration and through the lumen of the branch in a preloaded configuration.

Abstract: A pre-loaded delivery device that facilitates accurate placement of a stent graft assembly in the aorta is disclosed. A stent graft is carried on the delivery device and held in a pre-deployment configuration by a sheath. A split in the sheath facilitates the pre-cannulation of one or more branch arteries extending from the aorta before the stent graft is fully released in the aorta. The stent graft comprises a tubular body having at least one scalloped fenestration formed in one end of the graft material and at least one fenestration formed in the graft material of the main tubular body. A helical internal side branch extends from the fenestration within the lumen of the main tubular body. The helical side branch is configured to curve at least partially around the scalloped fenestration. The assembly further comprises a connection stent graft extending from the fenestration into a branch vessel.

Abstract: A stent graft for deployment into the aorta of a patient has a tubular body with a proximal portion of a selected diameter; preferably a reduced diameter portion, distal of the proximal portion, having a diameter less than the selected diameter; a tapered portion, extending between the proximal portion and the reduced diameter portion; and optionally a distal portion, distal of the reduced diameter portion. At least three, preferably four or five, low profile side arms are provided, preferably in the reduced diameter portion and/or the tapered portion, for connection of an arm extension to an aortic branch vessel. All but one of the side arms are to be connected at the physician's choice, depending on the anatomy of the patient. One side arm is to provide temporary profusion to external of the stent graft after deployment of the stent grant into the aorta, and is subsequently blocked.
