Abstract: A system for deploying a stent-graft within a body vessel is provided. The system includes an expandable stent-graft having expandable stent rings attached thereto and a cannula extending through the stent-graft. The system includes a plurality of diameter reducing connectors extending around the circumference of the graft for reducing the diameter of the graft. The system further includes a plurality of trigger wires extending longitudinally along the perimeter of the graft. The trigger wires extend through the diameter reducing connectors to constrain the connectors for reducing the diameter of the stent-graft. The trigger wires are also releasably attached to the apices of a bare stent portion extending from the proximal end of the graft body. The trigger wires can be sequentially retracted to release the bare stent and the diameter reducing connectors to expand the stent-graft radially into engagement with the wall of the body vessel.

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: A branched and fenestrated prosthesis may include a main tubular graft body including a proximal end opening, a distal end opening, a lumen, and a sidewall. A branch may extend from the sidewall and may include a first end opening, a second end opening, and a lumen. A fenestration may be disposed in the sidewall and positioned distal of the second end opening of the branch. The branched and fenestrated prosthesis may include a plurality of branches and a plurality of fenestrations.

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: 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: 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: An endograft comprising a proximal end and a distal end is disclosed. The endograft includes a tube of biocompatible material. The tube includes 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 includes a lateral cross-section defining a tubular wall pinched together by the seam to form a branch portion. The branch portion includes an entrance within the intermediate portion of the main lumen and an exit through the tubular wall of the main lumen.
