Abstract: 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 said blood vessel upon attachment thereto.

Abstract: A vascular prosthesis (50) comprises a tube (52) of material other than autologous vascular tissue, the tube having an end formation for surgical connection direct to an opening formed in an artery, the formation comprising an enlarged chamber (54) having a heel (56) and a toe (58) at opposite ends of a first longer diameter parallel to the axis of the tube and a second shorter transverse diameter the enlarged chamber serving to promote localised movement of blood having a non-laminar nature with a shear stress inducing relationship to receiving arterial wall.

Abstract: A vascular prosthesis comprising a tube of material other than autologous vascular tissue but considered/approved as safe and supple enough for use instead of such tissue, the tube having an end formation for surgical connection directly to an opening formed in an artery, the end formation serving to promote, at that end and/or within the direct connection and in response to normally pulsed blood flow, localized movement of blood having a non-laminar nature with a shear stress inducing relation to receiving arterial wall.
