Abstract
A vascular graft prosthesis includes a tubular conduit for subcutaneous implantation. The tubular conduit has a first end for attachment to a vein, a second end for attachment to an artery, and an enlarged portion between the first and second ends. The enlarged portion has a diameter greater than the diameter of a remaining portion of said tubular conduit. The enlarged portion is positioned proximate the first end and spaced from the first end a distance substantially equivalent to a length of the enlarged portion.
Claims17
A vascular graft prosthesis comprising:
- a tubular conduit for passage of blood therethrough, said tubular conduit having
- a first end for attachment to a first blood vessel,
- a second end for attachment to a second blood vessel, and
- no more than two, fluid-impermeable, enlarged portions positioned between said first end and said second end, each of said enlarged portions having an inner diameter greater than an inner diameter of a remaining portion of said tubular conduit, each of said enlarged portions being in fluid communication with said tubular conduit so that blood passing through said tubular conduit in a direction from said second end to said first end is entrained into, and recirculates within, each of said enlarged portions to slow the overall velocity of the blood through said tubular conduit.
