Abstract
Disclosed herein is a flexible single piece active element for use in connection with aspirating electrosurgical ablators, particularly those configured for bulk tissue vaporization. The active electrode elements of the present invention provide a simple construction suitable for use with a wide array of electrosurgical components and adjustable to wide range of angled positions to permit access to a variety of tissues, in an array of diverse environments and address a host of ablation needs. Additionally, the novel geometry and positioning of both ablation surface and aspiration ports permit aspiration flow to remove primarily waste heat rather than process heat, to thereby improve vaporization efficiency and reduce procedure time. Thus, active electrodes and ablation devices of the present invention maximize efficiency and adaptability while minimizing manufacturing cost and device profile.
