Abstract
A balloon catheter is provided which includes a flexible tube on one end of which a balloon is mounted to be inflated by means of the tube, which balloon has an annular restriction in its middle region in a plane approximately perpendicular to the tube axis. The balloon is produced in the form of a bag inside which the end of the tube is engaged, the opening of the bag being fixed to the outer wall of the tube, and the distal end of the balloon projects beyond the distal tip of the catheter tube to provide a cushioning region at the tip of the catheter assembly. A procedure for making the balloon is also described.
