Title: Method and system for preventing contrast associated nephropathy

Abstract: A method for preventing contrast associated nephropathy includes the steps of providing a multi-lumen dual balloon catheter and inserting the catheter into a patient's coronary sinus. The method also includes the steps of inflating the two balloons to block blood flow from the coronary sinus into the right atrium and draining blood containing contrast solution from between the two balloons through the catheter while the blood flow is blocked. A hemo filtration unit is used to remove contrast solution from the drained blood and the filtered blood returned to the right atrium. A multi-lumen dual balloon catheter is also disclosed.
