  • Methods of using high intensity focused ultrasound to form an ablated tissue area containing a plurality of lesions
    Patent number: 9227088
    Abstract: A device and method for ablating tissue is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding an ablating member within the patient while tracking the position of the ablating member in the patient, positioning the ablating member in a desired position to ablate tissue, emitting ablating energy from the ablating member to form an ablated tissue area and removing the ablating member from the patient.
    Type: Grant

  • Emission control unit
    Patent number: 4956152
    Abstract: An emission control unit is mounted in the exhaust line of a fossil fuel internal combustion engine and includes a tubular housing in which a lime sleeve is received. The sleeve has an axial opening through which a corona wire extends. Exhaust gasses pass through the sleeve along the wire. Placing a charge on the wire drives pollutants in the exhaust laterally outwardly into the sleeve at a direction which is 90.degree. to the direction of exhaust travel. The sleeve chemically interacts with the pollutants and neutralizes them with little hazard to the environment.
