Abstract: A stent is provided having a plurality of intersecting elongated members arranged to form a plurality of cells, which define an elongated tube with a lumen. The elongated tube has first and second sections, the first section having a substantially constant first diameter, the second section having a substantially constant second diameter that is larger than the first diameter. The elongated tube also has a transition section between the first and second sections, the transition section having a concave curvature extending proximally from the first section and a convex curvature extending proximally from the concave curvature to the second portion. A proximal end of the second section has a plurality of rounded ends formed by the plurality of intersecting elongated members. Each of the plurality of cells within the first section have a pitch that is tighter than each of the plurality of cells within the second section.

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 prosthesis delivery device and method are described herein. An elongate sheath extends about a longitudinal axis, and a hub is coupled to the sheath. A handle is distal to the hub, and a connector assembly is coupled to a proximal end of the handle. The connector assembly is removably coupled to the hub, and the connector assembly includes a longitudinal passageway defined therein in communication with the longitudinal hub lumen. In one aspect, the connector assembly includes a plurality of jaw elements, and an actuating ring operable to move the jaw elements between the attachment configuration where the jaw elements are coupled to the hub, and the detachment configuration where the jaw elements are radially displaced and decoupled from the hub to remove a component from the sheath lumen.

Abstract: A prosthesis delivery device comprises a proximal end and a distal end, a prosthesis retention section at the proximal end, and a prosthesis retained on the prosthesis retention section. The prosthesis has a proximal end releasably attached at the prosthesis retention section and a distal end releasably attached at the prosthesis retention section. A sheath is slidably disposed over the prosthesis. A delivery handle near the distal end the delivery device comprises a rotatable inner cannula having a cannula lumen and cannula handle. The cannula handle is rotatable with the inner cannula. Further, a positioner handle is releasably engaged with the cannula handle. Rotation of the inner cannula releases the proximal end of the prosthesis from the delivery device and withdrawal of the sheath from over the prosthesis releases the distal end of the prosthesis from the delivery device.

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 delivery system for a stent graft may include a stent graft having a proximal end, a distal end, an internal lumen between the proximal end and the distal end, a graft material tube, a graft material sidewall and a plurality of longitudinally spaced apart self-expanding stents attached to the graft material sidewall; a guidewire catheter extending longitudinally through the lumen of the stent graft; and a wire extending longitudinally along only a first side of the graft material tube in an undulating pattern of successive curves in alternate directions, the wire repeatedly extending through the graft material sidewall from inside the graft material tube to outside the graft material tube such that a portion of the wire extends over the guidewire catheter along a longitudinal length of the guidewire catheter to secure the guidewire catheter at least partially to an internal wall of the stent graft.

Abstract: A graft for inducing helical blood flow, including a tubular body with fluid inflow and fluid outflow ends, and with inner and outer sidewalls. A lumen extends between the fluid inflow end and fluid outflow end. A compressible chamber is disposed between the outer sidewall and the inner sidewall. The compressible chamber has an incompressible seam that follows a substantially helical path around a longitudinal axis of the tubular body. When internal (e.g., blood) pressure increases on the inner sidewall, a vane element is formed that follows the substantially helical path around the longitudinal axis of the tubular body. The vane element may induce helical blood flow. The width of the compressible chamber may decrease in a compressed state (e.g., systole). The chamber may be filled with a predetermined amount of at least one of a gas, liquid, or vapor. The graft may have a second incompressible seam/vane.
