<p>A catheter (10) having a torque transmitting shaft (14), a flexible catheter body (12) with a lumen (42) for passage of the shaft (14), and a balloon (16) mounted on the distal end of the catheter body (12) is disclosed. Flexible tubing (48) extends from within the balloon (16) to the distal tip of the catheter (10) and is bonded to the distal end of the balloon (16) so that the shaft (14) is free to move relative to the distal end of the balloon (16). The flexible tubing (48) may include a spring (72) covered by a tip tube (82), which is attached at its proximal and distal ends to the shaft (14).</p> |
