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.

Abstract: Prostheses and methods of making the same are provided. The prosthesis has an internal branch configuration. A trough or branch opening is at least partially defined by a trough wall extending into a main lumen from a sidewall of the prosthesis. The internal branch extends from the trough within the main lumen towards one of the outflow end of the graft body in a helical, retrograde arrangement. Other arrangements are described. The prosthesis may include a scalloped fenestration having a width larger than the trough. The trough may be positioned along a tapered region of the prosthesis. The trough and internal branch may be made from the same graft material. The trough and internal branch, in addition to the main graft body, may be made from the same graft material.

Abstract: Tissue cutting systems and methods of tissue cutting are provided. In one example, the tissue cutting system includes a first device and a second device adapted for coupling to a power supply. The first device includes a conductive probe. The second device includes a conductive material, for example, as part of an expandable structure, having an outer surface area of conductive material that may be larger than a surface area of the conductive probe. The conductive probe and the conductive material are deployed along opposite sides of a body tissue, such as an aortic dissection flap. Selective electrical power is applied to the conductive probe and the conductive material to cut the body tissue.

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: 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.
