An ablation apparatus includes an energy source producing an ablation energy output. A multiple antenna device is included and has a primary antenna with a longitudinal axis, a central lumen and a distal end, and a first secondary antenna with a distal end. The first secondary antenna is deployed from the primary antenna central lumen in a lateral direction to the longitudinal axis. The primary antenna is coupled to the energy source to receive the ablation energy output, and the first secondary antenna is coupled to the primary antenna to receive ablation energy from the primary antenna. A sensor is positioned at one or both of the primary or secondary antennas. A feedback control system is coupled to the energy source and the sensor. The feedback control system is responsive to a detected characteristic from the sensor to provide a delivery of ablation energy output from the energy source to the antennas.
