A catheter/guide wire steering mechanism includes a catheter (4) having a proximal end, a distal end, and sidewalls which define at least the first lumen (18). An opening (16) is formed in a sidewall (4a) of the catheter, near the distal end thereof in communication with the first lumen. A plug (20) is disposed in the catheter at the distal end thereof and includes a curved surface (24) for deflecting and directing out the opening, the leading end of a guide wire (12) (or other catheter) inserted into the lumen at the proximal end of the catheter. This enables guiding the guide wire laterally from the catheter either into a passageway branching from the main passageway into which the catheter is inserted, or to perforate a sidewall of the main passageway.
