A system, and method for treating a stenosis or blockage in a bodily fluid passageway is described. The system includes a catheter (10), and a controller for generating radio frequency energy along a pair of output lines (40a, 40b), a monitoring circuit (70) for monitoring the phase of the radio frequency energy along the output lines, and an impedance matching circuit (60). A lumen is provided through the catheter in order to deliver a mandril (18), and internal electrode (26) therethrough. Also, openings (132, 138) in a distal end of the electrode (26) is provided for delivering a medicine into the body of the patient at the areas treated with radio frequency energy.
