Abstract
A balloon catheter, preferably of the float-advancement type, defines a balloon carried adjacent the catheter distal end and a first catheter lumen communicating between the balloon at a proximal catheter location. By this invention, second and third, separate catheter lumens extend between proximal and distal catheter locations and are open at each end. The second and third catheter lumens are each proportioned to receive a catheter advancement guidewire to permit installation of a pair of the guidewires at desired body locations. Preferably, the second and third lumens define distal open ends which are longitudinally spaced from each other.
