Abstract
Abstract An ablation treatment apparatus includes an energy source. A multiple antenna device is included and has a primary antenna with a longitudinal axis, a central lumen and a distal end, and a secondary antenna with a distal end. The secondary antenna is deployed from the primary antenna central lumen in a lateral direction to the longitudinal axis. A selected primary or secondary antenna is electromagnetically coupled to the energy source. A non-selected antenna is electromagnetically coupled to the selected antenna. A cable connects the energy source to the selected antenna.
