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 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: 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 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 support structure for a three-sided scallop in the edge of a stent graft including two substantially longitudinal perimeter support sections and an undulating lateral side base extending between the two support sections. The undulations extend below the edge of the lateral side of the scallop and overlap the graft material away from the edge of the lateral side.

Abstract: Various stents and stent-graft systems for treatment of medical conditions are disclosed. In one embodiment, an exemplary stent-graft system may be used for endovascular treatment of a thoracic aortic aneurysm. The stent-graft system may comprise proximal and distal components, each comprising a graft having proximal and distal ends, where upon deployment the proximal and distal components at least partially overlap with one another to provide a fluid passageway therebetween. The proximal component may comprise a proximal stent having a plurality of proximal and distal apices connected by a plurality of generally straight portions, where a radius of curvature of at least one of the proximal apices may be greater than the radius of curvature of at least one of the distal apices. The distal component may comprise a proximal z-stent coupled to the graft, where the proximal end of the graft comprises at least scallop formed therein that generally follows the shape of the proximal z-stent. Further, the distal component may comprise at least one z-stent stent coupled to the distal end of the graft and extending distally therefrom that reduces proximal migration of the distal component.

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: 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.
