    摘要: A spiral blood flow device includes a stent made up of a plurality of expansion members joined to a plurality of axial members that permit the stent to change diameter among a continuum of expanded configurations. The axial members have fixed orientation, whereas the expansion members have a variable orientation relative to the longitudinal axis throughout the continuum of expanded configurations. A spiral flow inducing structure, which may include fins attached to the axial members, define a helical flow angle that remains constant throughout the continuum of expanded configurations.

    摘要: A stent used in reducing a diameter of a transjugular intrahepatic portosystemic shunt (TIPS) for secondary restriction of flow through a TIPS tract is disclosed. In one example approach, a reducing stent comprises a tube-shaped framework with a tubular material affixed around an outer surface of the framework and extending through the interior of the framework to define a reducing passage in the interior of the framework. In another example approach, a transjugular intrahepatic portosystemic shunt system including a transjugular intrahepatic portosystemic shunt and a reducing stent mounted within an interior of the transjugular intrahepatic portosystemic shunt is disclosed.

    摘要: A vascular prosthesis configured for direct connection to an artery. The vascular prosthesis may include a tube of material other than autologous vascular tissue, having an end formation, which is configured for surgical connection to an opening formed in the artery, and a narrower portion prior to commencement of the end formation. The end formation may have an enlarged chamber adapted to induce a concave section in the blood vessel upon attachment thereto.
