Patent number: 6437963Abstract: A method and apparatus for providing power to an electrostatic device includes a monitor and control system that prevents inadvertent and damaging electrical arcing. When the electrostatic device is first energized, voltage is gradually increased and the flow of electrical current is closely monitored. In the event the device is too close to ground or a grounded object, current flow exceeds a predetermined threshold and power is disconnected from the electrostatic device. Later, as the device voltage is increased to operating voltage, electrical current delivered to the electrostatic device is monitored for excessive current and excessive rate of change. If either fault condition is detected, power supply voltage may be reduced or disconnected, depending upon the severity of the fault. A microprocessor control system is illustrated for implementing the invention, including hardware and various software algorithms that provide the requisite gathering of information, analysis and responsive actions.Type: GrantFiled: September 24, 1999Date of Patent: August 20, 2002Assignee: EFC Systems, Inc.Inventors: John Bennett Hamilton, John Hamilton Long

Patent number: 6383181Abstract: A method and apparatus to treat Barrett's tissue, a pre-cancerous condition, by removing the epithelium above the lower esophageal sphincter through cryo-ablation. An endoscope with fiber optics is used to view the operation, and a catheter for supplying liquid nitrogen is passed through the lumen of the endoscope. Liquid nitrogen at low pressure is sprayed directly onto the Barrett's tissue through the catheter while the physician views the operation through the fiberoptics of the endoscope and controls the spray via a valve. Freezing is indicated by whiteness and shows that the epithelium has been cryoablated. The apparatus can also be used to treat various other gastrointestinal tract lesions. The catheter is insulated to withstand extremely cold temperatures without becoming stiff and without affecting the inherent flexibility and maneuverability of the endoscope.Type: GrantFiled: January 5, 2000Date of Patent: May 7, 2002Inventors: Mark H.
