The system is insertable through an instrument channel of a steerable instrument cord in an ENB instru- ment, and comprise a coaxial cable with a radiating tip portion. The tip portion comprises a first conductive element electrically con - nected to the coaxial cable' s inner conductor and a second conductive element electrically isolated from the inner conductor. The conductive elements are arranged to act as: an active electrode and a return electrode for delivering the RF energy into tissue sur- rounding the radiating tip portion, and an antenna for radiating the microwave energy as a localized microwave field. The system may be arranged to delivery energy according to a predetermined profile comprising interleaving periods of RF and microwave en - ergy or a combination thereof, or a dynamic profile based on detected tissue impedance. 111111111111110111011111111111010111110111010111011111111110111011111111111110111111 W O 20 1717 / 45 13 Al
