Patent number: 7480533Abstract: Ablative treatment of metastatic bone tumors and relief of pain associated with metastatic bone tumors is achieved by heat ablation of the bone tumor or tissue near the bone tumor by an ablation probe. In one form the probe is an electrode coupled to a high frequency power supply to provide ablative heating of tissue proximate to an electrode that is placed in or near the bone tumor. Cooling of the electrode by fluid circulation from a cooling apparatus outside the patient's body may be used to enlarge the region of high frequency heating around the electrode. Image guidance of the electrode placement may be monitored by an imaging device. Tracking of the electrode by an image-guided navigator helps in placement of the electrode with respect to the configuration of the bone and bone metastasis. A set of tools accommodates biopsy and various shapes of electrodes according to clinical requirements.Type: GrantFiled: March 31, 2005Date of Patent: January 20, 2009Assignee: Covidien AGInventors: Eric R. Cosman, William Rittman

Publication number: 20070043405Abstract: A method and apparatus for diagnosing and treating neural dysfunction is disclosed, which comprises taking the energy output from a high frequency generator module and delivering this energy as in a pulsed manner to a treatment electrode. In one exemplary embodiment, a temperature set point is utilized, and the pulses are modified to limit the energy delivered such that the temperature is limited. One exemplary method of modifying pulses includes reducing the amplitude of the pulses. Another exemplary method of modifying pulses includes reducing pulse width. Another exemplary embodiment of modifying pulses includes only delivering full width and amplitude pulses.Type: ApplicationFiled: August 18, 2006Publication date: February 22, 2007Inventor: William Rittman

Publication number: 20070032835Abstract: A method and apparatus for diagnosing and treating neural dysfunction is disclosed. This device has the capability of delivering the therapeutic electrical energy to more than one treatment electrode simultaneously. In another exemplary embodiment, this device can perform EMG testing both before and after the therapeutic energy has been delivered, to assess whether the target nerve was successfully treated. In another embodiment, the device has the capability to record and store sensory stimulation thresholds both before and after treatment is described, which allows the clinician to accurately determine whether the target nerve has been desensitized. Energy control may achieved by simultaneously comparing the tip temperature of each treatment electrode to a set temperature selected by the operator, and regulating the therapeutic energy output to maintain the set temperature.Type: ApplicationFiled: August 2, 2006Publication date: February 8, 2007Inventor: William Rittman

Patent number: 6416520Abstract: A probe is connected to a probe carrier that is positioned with respect to the body of a patient. The probe is moved into or out of the body incrementally by means of a driver mechanism and flexible coupler. The flexible coupler in one embodiment comprises a flexible sheath with a flexible driver shaft that can be passed within the flexible sheath and can be rotated or pushed forward and backward with respect to the sheath by a driver element thereby causing translational movement of probe. Several forms of probes, flexible coupling elements, and driver apparatus as well as methods of applications accommodate specific objectives.Type: GrantFiled: April 20, 2000Date of Patent: July 9, 2002Assignee: Sherwood Services AGInventors: Lutz T. Kynast, William Rittman, James P. O'Connor, Michael Cundari, Eric Cosman
