摘要： Systems and methods for applying ultrasound energy to a body region. The systems and methods provide an ultrasound applicator including a housing, an ultrasound transducer carried by the housing, and a chamber sized to hold an acoustic coupling media subject to a pressure in acoustic communication with the ultrasound transducer. The systems and methods generate electrical signals to operate the ultrasound transducer to output acoustic energy at a selected intensity level. The systems and methods sense at least one system parameter and compare the sensed system parameter to a desired level. The systems and methods vary the pressure in the chamber based, at least in part, upon the comparison.

摘要： Systems and methods deliver ultrasound energy to an ultrasound transducer having an impedance subject to variations. The systems and methods electrically couple an ultrasound generator to the ultrasound transducer to deliver ultrasound energy. The systems and methods deliver ultrasound energy to the ultrasound transducer at a set output frequency and at an output power level that remains essentially constant, despite variations in the impedance, based upon preprogrammed rules.

摘要： Systems and methods monitor and enable the use of a medical instrument that is configured to be operated in a prescribed manner. The systems and methods employ a use register sized and configured to be carried by the medical instrument, which comprises a memory field for recording a start date and time at an instance of first operation of the medical instrument. The systems and methods also employ a use monitoring controller, which is adapted and configured to be coupled to the use register. The use monitoring controller includes a start validation function that compares the start date and time to a present real date and time and provides a start validation output based upon the comparison. The use monitoring controller also includes an enablement function that enables operation of the medical instrument only if the start validation output meets prescribed criteria.

摘要： Ultrasound energy is delivered to an ultrasound transducer. The ultrasound energy is delivered at an output frequency that varies over time within a range of output frequencies, and a tuning function selects from within the range an operating output frequency for the ultrasound transducer based upon preprogrammed selection rules. The ultrasound energy is delivered to the ultrasound transducer at or near the operating output frequency selected, to perform a therapeutic or diagnostic function for a specified treatment time, after which operation of the ultrasound transducer is disabled.
