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.

Abstract:

The present disclosure relates to systems and methods for preparing a distal end of a femur for receiving a knee prosthesis. A method can include installing a valgus guide onto an intermedullary rod, coupling a drill guide with said valgus guide, resting a boom tip of said drill guide on a high part of the femur, drilling a hole into a distal portion of a medial condyle using a first drill hole of said drill guide and drilling a hole into a distal portion of a lateral condyle using a second drill hole of said drill guide, and, subsequent to drilling the first and second drill holes, resecting the distal portion of the medial condyle of the femur and the distal portion of the lateral condyle of the femur. A system can include a valgus guide, a drill guide, and a resection tower, among other things.
