    摘要： A high intensity focused ultrasound transducer includes an ultrasonic emitter having a surface that emits ultrasonic energy along a beam path, at least one low attenuation polymeric ultrasonic lens acoustically coupled to the surface in the beam path of the ultrasonic energy, such that the lens can direct the ultrasonic energy in at least one direction, and at least one stress mitigation feature, such as a kerf, a heat sink, or an acoustic matching layer, to mitigate thermal expansion mismatch stresses within the transducer. For manufacturing simplicity, the first surface is typically either flat or monotonically curvilinear. The lens may take a variety of shapes, including Fresnel features, and may focus, collimate, or defocus the ultrasonic energy. Any orientation and positioning of the at least one ultrasonic lens relative to the first ultrasonic emitter is contemplated. Manufacture is further simplified by molding, casting, or thermoforming the lens.

    摘要： A system and method for using a common subchannel to assess operating characteristics of one of a plurality of transducers that are coupled to said subchannel is disclosed. The plurality of transducers are divided into subsets and each subset is coupled to a subchannel. The system is configured to activate a selected transducer on the subchannel and the subchannel delivers operational information on the activated transducer. The present invention reduces the number of subchannels required to collect information on the plurality of transducers. The present invention may utilize one or more loading conditions to take at least one measurement, which at least one measurement is then used to derive operational information on the transducer. In one configuration, information on the amount of energy being delivered to the transducer is collected simultaneously with information on the operating temperature. In another embodiment only the temperature is measured. The present invention permits a more compact ablation device to be constructed based on the invention's ability to reduce the total number of subchannels required to collect transducer information.

    摘要： A method for ensuring two-sided telemetry in implantable cardiac therapy devices by making at least one of the following operating parameters selectable (reversible): (1) the direction of current detection of the telemetry circuitry of the implantable cardiac therapy device; (2) the direction of the magnetic field produced by the transmit coil of an external telemetry device (programming wand); (3) the direction of the magnetic field produced by the T/R coil of the implantable cardiac therapy device; and/or (4) the direction of current detection of the telemetry circuitry of the programming wand. In a presently contemplated implementation, when it is desired to read-out data from the implantable cardiac therapy device and/or to re-program the device parameters, a telemetry operation is attempted in the normal manner, i.e., it is initiated by the programming wand. If the communication is unsuccessful, then the direction of the magnetic field produced by the transmit coil of the programming wand is reversed, and the telemetry operation repeated. If the transmission of command data from the programming wand to the implantable cardiac therapy device is successful, but the transmission of read-out data from the device to the programming wand is unsuccessful, then the direction of current detection of the telemetry circuitry of the programming wand is reversed, and the telemetry operation is attempted again; alternatively, the direction of the magnetic field produced by the T/R coil of the implantable cardiac therapy device can be reversed. Thus, no matter what the orientation of the device and external telemetry device, successful two-way telemetry between the device and the programming wand is possible. Thus, the telemetry can be considered "two-sided". In an alternative embodiment, the telemetry operation can be initiated by the implantable cardiac therapy device. In this case, if the communication is unsuccessful, then the direction of the magnetic field produced by the T/R coil of the device is reversed.

    摘要： Embodiments of the invention controlling power distribution in an ablation control apparatus or the like. In one embodiment, a power switching apparatus comprises a first switch assembly having an input end to receive a power input signal, the first switch assembly having a plurality of output channels; a second switch assembly coupled to the output channels of the first switch assembly; a plurality of power receiving members coupled to the second switch assembly; and a controller controlling the first switch assembly to selectively transmit the power input signal to the output channels one at a time in a cyclical manner according to a first switching rate. The controller controls the second switch assembly to transmit the power input signal from the output channels of the first switch assembly to one subset of the power receiving members at a time according to a second switching rate, so as to transmit the power input signal to a subset of power receiving members one power receiving member at a time within the subset of power receiving members according to the first switching rate.
