Abstract
An electrode instrument is provided and includes an electrode head and a pair of electrodes for emitting RF energy for use in thermal ablation therapy. The electrodes are movable between a collapsed configuration and deployed configuration. When collapsed, the electrodes are proximate to each other, and when deployed, the electrodes are spaced apart from each other. The electrode instrument includes linkage mechanisms that are used to maintain the electrodes in their deployed configuration.
Claims20
An electrode instrument used for thermal ablation therapy, comprising an electrode head having at least a first and second electrode for emitting RF energy, said first and second electrodes being movable between a collapsed configuration, in which said first and second electrodes are proximate to each other, and a deployed configuration, in which said first and second electrodes are remote from each other and a first linkage mechanism connected between said first and second electrodes, for maintaining said first and second electrodes in their deployed configuration.
