    Abstract: Apparatus and methods for delivering high frequency energy to tissue with improved temperature sensing. The treatment apparatus may be a delivery device (14) positiortable adjacent to the tissue (30). The delivery device (14) may further include an electrode (16) adapted to deliver high frequency energy to the tissue (30) and at least one thermal sensor (64, 69, 75, 81, 100, 118, 130, 162, 202). In one embodiment, the thermal sensor (64, 100, 1 18, 130, 162, 202) may include one or more thermocouple junctions (70, 110, 112, 132, 142, 168, 175, 210, 214) of dissimilar metals formed by either thin film or thick film techniques. Alternatively, the thermal sensor (69, 75, 81) may include a body (74, 80, 82) composed of a resistive material having a resistance that varies with temperature to an extent sufficient to measure the skin temperature. A region of the delivery device near the thermal sensor may be heated by a heater (96), before skin contact is established during treatment, for purposes of detecting contact by the occurrence of heat loss from the delivery device region.

    Abstract: A long-term implantable ultrasound therapy system (11) and method is provided that provides directional, focused ultrasound to localized regions of tissue within body joints, such as spinal joints. An ultrasound emitter or transducer (16) is delivered to a location within the body associated with the joint and heats the target region of tissue associated with the joint from the location. Such locations for ultrasound transducer placement may include for example in or around the intervertebral discs (1), or the bony structures such as vertebral bodies or posterior vertebral elements such as facet joints. Various modes of operation provide for selective, controlled heating at different temperature ranges to provide different intended results in the target tissue, which ranges are significantly affected by pre-stressed tissues such as in-vivo intervertebral discs. In particular, treatments above 70 degrees C, and in particular 75 degrees C, are used for structural remodeling, whereas lower temperatures achieves other responses without appreciable remodeling.

    Abstract: A device and method for treating tissue at a treatment site. The device and method include supplying controlled energy to a heating portion of the device positioned within a tissue wall at the treatment site. The size of the heating portion and energy supplied provides for ablation of the tissue to form a cavity within the tissue wall without ablating the surfaces of the tissue wall. Treatment fluid can then be supplied through the device to the cavity to supplement growth of blood vessels or retard such growth of the treatment site. The device can also be used to create an injury zone at a treatment site without ablating tissue, wherein the injury zone can be injected with treatment fluid. The device and method has use anywhere within the body, especially in the regions of the heart.

    Abstract: An energy delivery system and method control the frequency of the power driving an ultrasonic device (24) to achieve more efficient power delivery. During operation of the ultrasonic device to deliver power to a patient site (16), the system and method automatically sweep the drive power through a frequency range, locate the series and parallel resonance frequencies, calculate the average of those frequencies and lock the power generator at that average frequency to drive the crystal. This frequency sweep procedure occurs automatically when the ultrasonic crystal is located at the patient site and the power generator operator presses the power-on switch to apply power. The method of tuning the power generator thus occurs when the crystal is at the site temperature and is transparent to the operator. The application of an external bio-layer to the crystal increases its bandwidth and its robustness. Mounting a temperature sensor (28) or sensors at the crystal permits monitoring of the crystal temperature and allows drive level control over the power generator to control the temperature at the crystal.

    Abstract: An apparatus including an aspiration conduit (1), a pump (2) and a pressure transducer (3) and logic console (4) which determines vacuum level fluctuations in the aspiration conduit. The aspiration conduit is connected to a surgical cavity. The pump (2) creates a vacuum in the aspiration conduit (1) downstream and transports the fluid and/or tissue material from the surgical cavity, through the aspiration conduit and into a collection container (11). The logic console (4) responds to a predetermined rate of decrease in vacuum in the aspiration conduit (2) and causes an electric signal to be sent to the pump (2), which upon receipt of the signal reverses its action and/or to an electromechanical valve located along the aspiration conduit (2) that in response to receipt of the signal occludes the aspiration conduit and terminates the removal of tissue or fluid from the surgical cavity. The reversal of rotation prevents the occurrence of a fluid surge that would result in the collapse of a surgical cavity. In addition, a surgical tool (24) is disconnected from its source of power when the temperature of the surgical tool is above a predetermined value.
