Abstract
A device for tissue ablation comprises plural arrays of segmented needle electrodes, each of which contains a plurality of electrically conductive segments, a plurality of non-conductive joints, and a needle tip. Each of the electrically conductive segments is wired to a radio-frequency electrical power source and can be connected to and disconnected from the power source. After the needle electrodes of the device are penetrated into a target tissue to be ablated, the intended volume of ablation can be configured in three dimensions. Thus, the device allows physicians to effectively control ablation boundaries.
