  • Publication number: 20240423697
    Abstract: Systems described herein include a two-tip handpiece that delivers current from two sources at two different frequencies. Signals at different frequencies are absorbed differently in the body. Accordingly, both monopolar and bipolar systems using this two tip handpiece and dual-frequency signal can detect impedance (or other frequency dependent characteristics) of the target tissue at the tips while delivering treatment, which was not possible or practical using conventional systems.

  • Publication number: 20240197384
    Abstract: Systems and methods whereby an electrosurgical device provides electrosurgical treatment to a tissue area while offering simultaneous irrigation and suction capabilities. A hybrid pump attachment including a plurality of flexible tubes is fluidly connectable to the electrosurgical device, wherein the plurality of flexible tubes is orientated within the hybrid pump attachment such that, when attached to the peristaltic pump, the plurality of tubes at least partially surrounds a rotor and a plurality of rollers of the peristaltic pump. The rotor is rotatable about a central axis such that the plurality of rollers conveys fluid through the plurality of flexible tubes by way of applying intermittent forces on the external surface of the plurality of flexible tubes, wherein at least a first tube conveys a first fluid to a first location and at least a second tube conveys a second fluid to a second location.

  • Publication number: 20240204645
    Abstract: An electrosurgical system includes a generator and an electrosurgical device and is configured to establish two-way communication using a resistance level communication protocol. The electrosurgical device includes an electrical connector configured to receive a treatment signal and a continuous signal from the generator, an AC-DC converter configured to convert the continuous signal, a processor configured to receive the converted continuous signal, and a resistor connected to the processor and configured to vary the current of power used by the processor over time. The generator is configured to interpret variances in the current as data and to provide an acknowledgment to the electrosurgical device.

  • Publication number: 20240008912
    Abstract: An electrosurgical device configured to harvest RF energy to provide power to one or more loads. The electrosurgical device including a distal portion having two electrodes configured to introduce electrical current into tissue and a proximal portion coupled to an electrical connector. The electrical connector is configured to provide a treatment signal and a continuous signal to an energy harvesting assembly housed within the electrosurgical device. The energy harvesting assembly includes a transformer configured to isolate and reduce the treatment signal to a lower voltage, an AC-DC converter configured to convert the AC signal to DC, and a DC-DC regulator configured to output a fixed voltage. The one or more loads can be electrically coupled to the energy harvesting assembly such that the one or more loads are powered by the fixed voltage.

  • Publication number: 20220265347
    Abstract: Devices, kits, and methods described herein are usable for medical treatments by generating local maxima using constructive interference of multiple oscillator outputs. Where constructive interference occurs between the oscillator waves, the output signal can have significant strength to cause heating and coagulation at a bleeding vessel, for instance, while at areas with little interaction (or with destructive interference) there is insufficient power dissipated by the output signal to cause heating sufficient to cause coagulating heating.
