  • Patent number: 11903630
    Abstract: An electrosurgical apparatus with a retractable blade for use in cold plasma applications, electrosurgical cutting and mechanical cutting is provided. The electrosurgical apparatus employs a tip of the retractable blade as a sharp conductive point to generate a plasma beam or discharge. When the blade is retracted within the electrosurgical apparatus, it is electrically energized while an inert gas flows over it, producing a cold plasma discharge. In the de-energized state, the blade is advanced and used as a traditional, mechanical surgical blade.

  • Patent number: 11883088
    Abstract: Apparatus and associated methods relate to controlling electrical power of an electrotherapeutic signal that is provided to a biological tissue engaged by an electrosurgical instrument during a medical procedure. Electrical power—a product of a voltage difference across and an electrical current conducted by the engaged biological tissue—is controlled according to a therapeutic schedule. The electrotherapeutic schedule can be reduced or terminated in response to a termination criterion being met. In some examples, the termination criterion is a current characteristic, such as, for example, a decrease in current conducted by the engaged biological tissue. In some examples, the termination criterion is a biological tissue resistance characteristic, such as, for example, an increase in the biological tissue resistance that exceeds a predetermined delta resistance value.

  • Patent number: 11877784
    Abstract: A technique allows for an electrical connection between a thermal abrasion heating catheter and the energy delivery console that utilizes serial communication. Accordingly, the serial communication allows data such as measured temperature, start/stop status, intended treatment area, device identification, device calibration parameters and/or use history to be conveyed along the same wires that deliver power to a heating element. For example, data can be conveyed along a two wire connection and provided at a frequency that is filtered out so that it is not delivered to a heating feature. In this example, one wire provides power to the heating element, one wire provided communication from the energy delivery console, and a third wire provides a common ground which the heating catheter uses to communicate with the energy delivery console.

  • Patent number: 11864811
    Abstract: A method for performing cold atmospheric plasma therapy to treat breast cancer. The cancerous tumor is sampled and cold atmospheric plasma treatment is performed on sampled cancerous tumor cells ex vivo. The results of the testing are stored in an electronic storage media. A cell viability reduction rate of said tested samples is calculated with a processor and stored in memory. An average cell viability reduction rate is then calculated by the processor for the cancerous tumor. Cold atmospheric plasma dosages to be used in treatment of the cancerous tumor in vivo are then projected using the processor. The tumor is surgically removed from the patient. The surgical margins of the tumor are then treated with cold atmospheric plasma at the projected dosages.

The knife drive assembly includes a trigger slidably coupled with the housing, an actuating assembly, and a return assembly. The actuation assembly converts proximal translation of the trigger into distal actuation of the knife. The return assembly automatically actuates the knife from the fired position to the pre-fired position in response to the trigger reaching a predetermined proximal position. The lockout assembly prevents activation of the electrode and distal actuation of the knife while in the locked configuration.
