Patent number: 7993289Abstract: Described is a system and method for the destruction of adipose tissue using an energy applicator such as a HIFU transducer. The system has a scan head containing an energy applicator, a mechanical arm for carrying the weight of the scan head, and a therapy controller such as a computer for controlling the operation of the scan head. The therapy controller may be part of a general purpose computer, and may be used as a robotic controller to automate the procedure. Methods are included for destroying adipose tissue in a quick, non-invasive manner.Type: GrantFiled: December 29, 2004Date of Patent: August 9, 2011Assignee: Medicis Technologies CorporationInventors: Jens U.

Publication number: 20110077559Abstract: A therapy head for use in HIFU procedures is described. The therapy head has an enclosure with a window, an energy applicator and a means of moving the energy applicator within the enclosure. The therapy head uses motors and actuators to move the energy applicator, usually an ultrasound transducer, inside the enclosure. A controller is provided either internally or externally that allows the therapy head to identify and distinguish locations where the therapy head should be to radiate energy into a patient. The controller uses the motors and actuators to move the energy applicator into the desired locations.Type: ApplicationFiled: December 6, 2010Publication date: March 31, 2011Applicant: Medicis Technologies CorporationInventors: Jens U. Quistgaard, Tim Etchells, Gregory Paul Darlington, Charles S. Desilets

Medical diagnostic ultrasound instrument with ECG module, authorization mechanism and methods of use
Patent number: 7686766Abstract: A handheld ultrasound instrument is disclosed having enhanced diagnostic modes including pulse/continuous wave Doppler, time-motion analysis, spectral analysis and tissue harmonic imaging. An external electrocardiograph (ECG) recording unit is also disclosed. The ECG unit is adaptable to be used with the handheld ultrasound instrument to provide for ECG monitoring while performing an ultrasound scan in B-mode, Doppler, color Doppler, M-mode, and CW/PW mode. The enhanced handheld ultrasound instrument further includes a security mechanism allowing any combination of the diagnostic modes to be enabled by the manufacturer, and later to enable or disable any one or group of the diagnostic modes. The invention also discloses a method for a manufacturer to maintain a database of handheld ultrasound instrument capabilities after the instruments enter the stream of commerce.Type: GrantFiled: August 17, 2005Date of Patent: March 30, 2010Assignee: SonoSite, Inc.Inventors: Jens U.
