Abstract
A balloon catheter has a combined balloon inflation and guide wire lumen. A guide wire tube in a distal port of the lumen inhibits loss of inflation medium through the port even when the balloon is inflated at relatively high pressures. The guide wire tube provides sufficient clearance with the guide wire, however, so that the catheter may be axially translated over the guide wire without excessive friction.
