Abstract: The apparatus for diverting blood from the retro hepatic inferior vena cava (IVC) and internally shunting renal and infra renal IVC blood into the right atrium during surgery on the liver, its vessels, or the retro hepatic IVC is described. It is symmetrical on its mid horizontal axis permitting similar utility whether venous access was above or below the liver. It is a hollow plastic tube with two sidewall openings, one at each end with four intervening completely encircling balloons. It is continuous with a proximal component which serves to remotely manipulate, infuse fluids and inflate the balloons in the distal component. Once introduced into the venous system by right atriotomy or infrarenally by venotomy, the distal component would be advanced and seated in the right atrium and supra renal IVC.

Abstract: Disclosed is a method of diverting blood from the adult retro hepatic Inferior Vena Cava (IVC) and the shunting of renal and infra renal IVC blood to the right atrium when desired during surgery on the liver, its vessels, or the retro hepatic IVC. The device has a distal component of critical length for the adult supra renal IVC. It is symmetrical on its mid horizontal axis permitting similar utility whether venous access was above or below the liver. It is a hollow plastic tube with two openings, one at each end of the tube, which has four intervening completely encircling balloons and is continuous with a proximal component which serves to manipulate the distal component within the venous system and to remotely inflate the balloons.
