Abstract
An improved balloon catheter with an inferior vena cava blood shunt or bypass is provided. Posterior and anterior ports in the wall of the catheter connect to a common lumen within the catheter, forming a shunt or bypass for blood flowing in the blood vessel. The blood shunt or bypass spans the blockage in the blood vessel generated by enlargement of the balloons of the balloon catheter. Bypass port closure apparatus is provided which is operated at the external end of the catheter. The bypass port closure device functions to open and close at least one of the ports of the bypass, effectively opening and closing the bypass.
