Abstract
Arteriovenous grafts are utilized as connections between arteries and veins so that blood may be withdrawn and/or reintroduced. A number of pressure reducing graft configurations may be utilized to lower the static pressure on the venous side to a level closer to that on the arterial side.
Claims21
An arteriovenous shunt comprising a member having an internal diameter configured to produce a pressure drop across the length of the member when one end of the member is connected to an artery and another end of the member is connected to a vein.
An arteriovenous shunt comprising a tapered elongate structure having a first end with a first diameter and a second end with a second diameter, the first diameter being greater than the second diameter, wherein the first end is configured for attachment to an artery and the second end is configured for attachment to a vein.
An arteriovenous shunt comprising an elongate structure having a first section with a first diameter, a second section with a second diameter and a third section with a third diameter positioned between the first and second sections, the first and second diameters being substantially equal and greater than the third diameter, wherein the first section is configured for attachment to an artery and the second section is configured for attachment to a vein.
