Vascular prosthesis

摘要

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, localised movement of blood having a non-laminar nature with a shear stress inducing relation to receiving arterial wall.
