ABSTRACT:
A method of obtaining x-rays of blood vessels of the circulatory system involving injection of radiopaque dye using a novel balloon catheter is described. The novel balloon catheter has a tube with two separate lumens, for each conducting a separate fluid flow along the length of the tube. An orifice is provided in each lumen at the proximal end of the tube for separately introducing a fluid flow into each lumen. A distal tip end of the tube has perforations for perfusing fluid flow from only the first lumen to an exterior of the catheter. A balloon, provided proximal of the perforations of the distal tip end of the tube, is in fluid flow communication with only the second lumen to provide selective fluid inflation of the balloon.
