A method and device for removing a first guide catheter and replacing the first guide catheter with a second guide catheter, without disturbing the placement of a flexible guide wire which has previously been inserted through the first guide catheter. The device of the invention comprises an 'exchange catheter' which may be advanced over the outer surface of the pre-positioned guide wire to provide support and shielding of the guide wire during the catheter exchange procedure. A guide wire exit aperture formed in the 'exchange catheter' permits the guide wire to exit the exchange catheter at a location whereby the operator may hold and manipulate the guide wire to maintain its desired position during the catheter exchange procedure.
