Patent number: 9816968Abstract: A method and system for checking functionality of an ultrasound therapy head. The waveform profile for typical ultrasound reflections for a functional therapy head are stored, and before use of a therapy head, an ultrasound energy burst (700) is sent, and the actual waveform profile of the returned reflections (702) are compared to the stored waveform profiles (706). If the actual profiles are not sufficiently close to the stored profiles, then a first signal (712) may be generated, which may cause the ultrasound therapy device to shut down or may generate a warning. If the actual profiles are sufficiently close to the stored profiles, then operation may continue (714), or a second signal may be produced, permitting operation of the ultrasound therapy device.Type: GrantFiled: March 23, 2010Date of Patent: November 14, 2017Assignee: LIPOSONIX, INC.Inventor: Blake Little

Patent number: 9623267Abstract: Methods and apparatus (100) are described for modifying unwanted tissue for cosmetic reasons. The methods provide a non-invasive manner to perform body contouring by destroying adipose tissue while simultaneously causing collagen contraction in a single procedure. Adipose tissue destroyed during the medical procedure may be removed from a treatment volume during the wound healing process, allowing the treatment volume to gradually shrink (22). The gradual shrinkage may promote better skin tone in the treatment area. The procedure may involve multiple treatments to the same treatment area or location.Type: GrantFiled: March 4, 2010Date of Patent: April 18, 2017Assignee: LIPOSONIX, INC.Inventors: Tanar Ulric, Charles S. Desilets, Blake Little

Patent number: 9289188Abstract: An ultrasound transducer and methods of fabricating and using the ultrasound transducer. The ultrasound transducer includes a composite layer having a first surface and comprising a plurality of piezoelectric elements separated by isolating material filled kerfs. The composite layer is configured so that the first surface includes an exposed face of each element of the plurality of piezoelectric elements. The transducer further includes a plurality of electrodes defined on the first surface, the electrodes having boundaries configured so that none of the exposed faces are in contact with more than one of the plurality of electrodes. The electrodes may be defined in a conductive layer deposited on the first surface of the composite body by forming a channel in the conductive layer that is aligned vertically with the dielectric kerfs.

Publication number: 20140024975Abstract: Devices, systems, and methods for increasing the accuracy of ultrasound power delivered to and received from a patient by an HIFU system having exchangeable components. The system components include one or more memory devices in which calibration parameters for the component are stored, such as when the component is manufactured. During operation of the system, the calibration parameter data is received from the memory and used by the system to adjust the output power of one or more ultrasound sources and/or received signal levels based on the received calibration parameters. The calibration parameters may include data relating to impedance, sensitivity, transfer functions, linearity, or other data that could affect the power delivered to a patient by the component.Type: ApplicationFiled: July 17, 2012Publication date: January 23, 2014Applicant: LIPOSONIX, INC.Inventors: Blake Little, Tanar Ulric
