ELECTROSURGICAL PROBE HAVING CURRENT ENHANCING PROTRUSIONS

摘要

Tissue ablation probes and methods of treating diseased tissue using one or more probe components that include one or more current enhancing protrusions are disclosed. An uninsulated, electrically conductive section of the shaft can include one or more current enhancing protrusions. Conductive elements or individual electrodes of electrode arrays can also include current enhancing protrusions. The current enhancing protrusions increase current density around the uninsulated outer surface and/or conductive elements to bias or enhance tissue ablation.
