An angioplasty catheter includes a coaxial transmission line with an elongated center conductor and outer conductor. The transmission line terminates at the distal end in an antenna and a balloon. A longitudinal central bore through the center conductor is dimensioned to accept the guide filament. The center conductor is made from a metallized TEFLON polytetrafluoroethylene fluorocarbon tube.
