Patent number: 7001379Abstract: Method for heating tissue by delivering radio frequency energy through tissue electrodes having controlling energy delivery so that an abrupt increase in impedance between the electrodes and the tissue is observed, typically in the form of an abrupt decrease in power delivered to the electrodes. The power at which the impedance increases and/or the time required to induce such an increase in impedance, are relied on to determine acceptable ranges to achieve a maximum sustainable delivery of radio frequency energy to the tissue consistent with complete, rapid, and uniform heating of the tissue.Type: GrantFiled: January 12, 2004Date of Patent: February 21, 2006Assignee: Boston Scientific Scimed, Inc.Inventors: Robert S. Behl, Eben L. Kermit, Peter F. Lyons, Colin J. Nichols

Patent number: 6889089Abstract: A system for treating a target region in tissue beneath a tissue surface comprises a probe for deploying an electrode array within the tissue and a surface electrode for engaging the tissue surface above the treatment site. Preferably, surface electrode includes a plurality of tissue-penetrating elements which advance into the tissue, and the surface electrode is removably attachable to the probe. The tissue may be treated in a monopolar fashion where the electrode array and surface electrode are attached to a common pole on an electrode surgical power supply and powered simultaneously or successively, or in a bipolar fashion where the electrode array and surface electrode are attached to opposite poles of the power supply. The systems are particularly useful for treating tumors and other tissue treatment regions which lie near the surface.Type: GrantFiled: April 11, 2001Date of Patent: May 3, 2005Assignee: SciMed Life Systems, Inc.Inventors: Robert S. Behl, Eben L. Kermit
