Filed:

Dec 18, 2009

Appl. No.:

12/642686

Inventors:

Lukas Hunziker - Brisbane CA, US
Justin May - Redwood City CA, US
Tonee Smith - Redwood City CA, US

Assignee:

Cutera, Inc. - Brisbane CA

International Classification:

A61N 7/02

US Classification:

601 2, 601 3

Abstract:

An ultrasonic transducer system for treating a portion of tissue. The ultrasonic transducer system includes a frequency generator, an ultrasonic transducer, and a transmitter element. The transducer receives an AC voltage from the frequency generator and produces an ultrasonic energy pulse at an ultrasonic frequency for a pulse width. The transmitter element is coupled to the transducer and is for irradiating a portion of skin tissue. The transmitter element has a chilled surface in contact with the skin tissue and an acoustic aperture for producing a substantially collimated energy beam. The beam has a width greater than 4 mm.

International Classification:

G01H 13/00
G01N 29/00

US Classification:

73579, 73 182

Abstract:

Systems, apparatus, and methods for controlling acoustic power delivery at ultrasonic frequencies. An embodiment of the invention comprises an ultrasonic device including an ultrasonic transducer and an acoustic sensor having a fixed acoustic coupling to the transducer. A method of the invention may include sensing acoustic power output from the ultrasonic transducer in response to a calibration signal, and determining a drive frequency for a working drive signal to enable efficient and controllable operation of the transducer. The invention may be used for automatically re-calibrating ultrasound systems for optimum performance at frequencies including the range of 3 to 12 MHz.

Assignee:

CUTERA, INC. - Brisbane CA

International Classification:

A61N 7/00

US Classification:

601 2

Abstract:

A dermatological treatment device that includes an ultrasound transducer and at least one matching layer mechanically interfaced to an output surface of the transducer. The ultrasonic transducer has a fundamental resonant frequency and the at least one matching layer has a thickness about equal to an odd multiple of a quarter-wavelength of the fundamental frequency. A drive circuit applies an electrical power input to the ultrasonic transducer. The electrical power input has a drive frequency that is an odd harmonic of the fundamental resonant frequency of the ultrasonic transducer, and a drive voltage greater than 55 volts. The electrical power input results in an ultrasonic transducer output with a power intensity greater than 150 W/cm.
