A medical catheter is provided which includes a core wire extending longitudinally through inflation tubing. The inflation tubing defines an inflation lumen. The distal end of the inflation tubing extends longitudinally through a tubular first reinforcement band which terminates distal to the distal end of the inflation tubing. An inner lumen tube defines a guidewire lumen, the inner lumen tube being biaxial with the inflation tubing and running longitudinally along the outer diameter of the inflation tubing. The inner lumen tube extends longitudinally through a shim tube which has a longitudinal slit running along its top side. The inner lumen tubing which has the shim coaxially bonded thereon extends longitudinally through a shaft tube. The inflation tube with the first reinforcement band coaxially bonded thereon also extends longitudinally through the shaft tube. The shaft tube is bonded to the inner lumen tube and to the inflation tube. A metal piece may be bonded to the inflation tube. An inflatable balloon is mounted at the distal end of the shaft tube, the balloon is in fluid communication with the inflation lumen.
