Abstract

An ablation treatment apparatus has a multiple probe device. The multiple probe device includes a primary electrode/probe/antenna with at least one lumen, a longitudinal axis and an ablative surface area of length L1. The multiple probe device also includes a secondary electrode/probe/antenna that is positioned in a lumen of the primary probe as this last is introduced through tissue. A secondary electrode/probe/antenna distal end is slidingly deployed at a selected tissue site from the primary electrode/probe/antenna lumen in a lateral direction relative to the longitudinal axis. A sensor is at least partially positioned at an exterior of the secondary electrode/probe/antenna distal end at a distance L2 from the primary electrode/probe/antenna along the secondary electrode/probe/antenna distal end. L2 is at least equal to 1/3 L1. An energy source is coupled to the primary electrode/probe/antenna.
