    摘要： Systems and methods deliver ultrasound energy to an ultrasound transducer. In one arrangement, the ultrasound energy is delivered at an output frequency that varies over time within a range of output frequencies. The systems and methods select from within the range an operating output frequency for the ultrasound transducer based upon preprogrammed selection rules. The systems and methods can deliver ultrasound energy to the ultrasound transducer at or near the operating output frequency selected, to perform a therapeutic or diagnostic function. In another arrangement, the systems and methods deliver ultrasound energy to the ultrasound transducer at or near a first output power condition to perform a first function, as well as at or near a second output power condition that differs from the first output power condition to perform a second function that differs from the first function. In this arrangement, the systems and methods deliver ultrasound energy to the ultrasound transducer at a power condition that transitions, according to a ramping function, from a condition at or near the first output power condition, for execution of the first function, toward a condition at or near the second output power condition, for execution of the second function. The ramping function may, e.g., be linear or non-linear.

    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： A cryosurgical system comprises a compressor unit and a probe assembly. A secondary refrigerant stream from the compressor unit pre-cools a heat exchanger within the probe assembly in a standby mode of operation. After the heat exchange is pre-cooled, a primary refrigerant stream can be passed through the cooled heat exchanger and thereafter expanded within a tissue-contacting portion of the probe assembly to achieve very low temperatures, typically minus 100° C. or lower. After cooling, the refrigerant stream may be passed through the probe assembly with no or partial expansion to warm the tissue-contacting surface of the probe. A probe sheath can be used to provide sterility.

    摘要： The present invention provides devices, systems, and methods for using a single electrode structure for both resection and ablation. Generally, the electrode structures of the present invention comprise fixed wire shapes which avoid the complexity and binding that often result when known rolling ablation elements are powered to the high electrosurgical potentials required for removal of tissues. Electrosurgical energy requirements are minimized by concentrating potential at narrow cutting surfaces, and physician effort is avoided by minimizing the total profile of the device along a selected cutting axis. In the exemplary embodiment, a serpentine wire has multiple electrosurgical elements which are aligned with a low cutting profile, and which provide a large lateral surface area for simultaneous ablation of uterine and other tissues.
