  • Patent number: 12096971
    Abstract: An apparatus includes a shaft assembly. A sliding electrical coupling provides electrical continuity between components of the shaft while permitting movement of a second shaft component relative to a first shaft component at the joint. An end effector is positioned at a distal end of the shaft assembly and is operable to engage tissue of a patient. A sensor is positioned adjacent to the joint and is configured to measure a joint parameter indicating a state of the sliding electrical coupling. The sensor transmits a first signal indicative of the measured joint parameter to a control module. The control module determines whether the measured joint parameter exceeds a maximum deviation from a predetermined value. When the measured joint parameter exceeds a maximum deviation from a predetermined value, the control module initiates a responsive action.

  • Patent number: 12090086
    Abstract: Systems and methods for manipulating the temperature of a surface are described. Described embodiments include thermal adjustment devices that may include a heatsink and that are operated in two or more modes of operation to apply a desired temperature to a user. In one operating mode the thermal adjustment device may apply a first temperature to an underlying surface while generating heat at a rate faster than the heatsink's heat dissipation rate. The thermal adjustment device may then apply a second temperature to reduce the rate of heat generation to be less than the heatsink's heat dissipation rate. These modes of operation may be applied cyclically to permit continuous operation of the thermal adjustment device. In some embodiments, the temperature profile applied when changing between the modes of operation may be selected such that the user experiences either a reduced, or substantially, neutral thermal sensation.

  • Patent number: 12076070
    Abstract: Methods and devices for performing ablation using time multiplexed waveforms are disclosed. The increased efficacy of monophasic waveforms is combined with the reduced side effects of biphasic waveforms by distributing components of the waveform across over a broader time interval than that typically used in a conventional biphasic waveform. Charge balancing occurs upon completion of therapy delivery within a time period that avoids muscle stimulation, while allowing unbalanced waveforms to be delivered during stimulation.

  • Patent number: 12064173
    Abstract: An apparatus capable of generating high power microwave frequency pulses for use with an electrosurgical device. The apparatus may be used for coagulating or ablating biological tissue. The apparatus includes an amplifier line-up comprising: a microwave signal generator for generating microwave radiation; a modulator arranged to pulse the microwave radiation; and an amplifier module arranged to increase the power of pulses of microwave radiation. The amplifier module works by providing a set of amplifiers that exhibit a gain that is greater than the total loss experienced at the components that divide the input signal and then combine the output signals. For example, if each amplifier in the array has a gain of 10 dBm, it is viable to use conventional power splitters and combiners to obtain an output microwave signal with substantially higher power than is provided by conventional electrosurgical generators.

  • Patent number: 12059196
    Abstract: A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector assembly at a distal end portion of the shaft, and a drive assembly. The drive assembly includes a movable handle, a carriage operably coupled to the movable handle, an inner drive operably coupled to the end effector assembly, and a spring assembly operably coupling the carriage and the inner drive. The spring assembly includes inner and outer coil springs arranged in a nested configuration. Initial actuation of the movable handle slides the carriage such that the spring assembly transfers the sliding of the carriage into translation of the inner drive to apply a jaw force by the end effector assembly. Subsequent actuation of the movable handle slides the carriage to compress the spring assembly to substantially maintain a position of the inner drive, thereby controlling the jaw force.
