METHOD AND APPARATUS FOR PRECISELY CONTROLLING THE SIZE AND SHAPE OF RADIOFREQUENCY ABLATIONS
摘要
<p>Various embodiments of multielectrode radiofrequency (RF) ablation probes are described herein that disclose methods and apparatus for improved control and predictability of the size and shape of RF thermal electrocoagulations. The features of the invention include the ability to make irregularly shaped ablations in order to conform to irregularly shaped target tissue volumes, and to make very large ablations without the requirement for electrode cooling.</p>
