    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: 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 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: A system for supporting or dilating a body vessel includes a balloon catheter with a shaft having a delivery lumen in communication with an interior of the balloon. The balloon includes holes formed in the outer wall of the balloon. Additional or daughter balloons are delivered through the delivery lumen into the cavity of the balloon and through the holes into engagement with the holes. The daughter balloons are inflatable to seal against the holes, and the main balloon is subsequently inflatable when sealed by the daughter balloons. The daughter balloons may be delivered to branch vessels to provide support in addition to the inflation of the main balloon. The system may include preloaded wires extending through the delivery lumen and through the holes, and the daughter balloons can be delivered over the wires to the desired location.

    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.
