  • Patent number: 11369426
    Abstract: A method of operating a power source device for a high-frequency treatment instrument adapted to perform high-frequency treatment for biological tissue includes causing a high-frequency power source circuit to output power; setting a target impedance value which gradually increases from a change-over impedance value to a stop impedance value; regularly comparing a measured impedance value to the target impedance value; causing the high-frequency power source circuit to lower the power by a first ratio if the measured impedance value is greater than the target impedance value, and to raise the power by a second ratio if the measured impedance value is smaller than the target impedance value; and causing the high-frequency power source circuit to terminate the output upon the value for impedance reaching the stop impedance value.

  • Patent number: 11364072
    Abstract: Methods, systems, and devices for enhancing the efficiency and efficacy of energy delivery and tissue mapping. One system includes a treatment element having a plurality of electrodes and an energy generator that is configured to deliver electric energy pulses to the electrodes in a variety of patterns. For example, electrodes may be arranged in closely spaced pairs. The energy generator may deliver mapping energy to each electrode in each pair individually to map tissue and may deliver ablation energy to the electrodes in each pair together, such that each pair is treated like a single electrode, to deliver ablation energy, such as bipolar ablation energy between adjacent pairs. One system includes at least one concave electrode, the configuration of which concentrates the energy and drives it deeper into the tissue. One system includes neutral electrodes between active electrodes, the energy generator selectively coupling the neutral electrodes to alter the ablation pattern.

  • Patent number: 11337747
    Abstract: A system for use with a surgical instrument includes an end effector, a memory circuit to store computer-executable instructions, and a processor. The end effector comprises a cutting member and a load cell sensor configured to sense a measure of force used to advance the cutting member through captured tissue. The processor is configured to execute the computer-executable instructions to initiate a first treatment cycle, access the measure of force used during the first treatment cycle to advance the cutting member through the captured tissue, determine that the measure of force exceeds a predetermined threshold, and generate an alert to a user of the surgical instrument based on the determination that a value of the measure of force exceeds the predetermined threshold. The predetermined threshold is based on an accumulation of biological material on the cutting member and a normal operational parameter of the first treatment cycle.

  • Patent number: 11291493
    Abstract: Conventional vasectomy techniques suffer from a number of potential complications, including, for example, a substantial risk for the development of hematomas, and swelling, and post-surgical pain, a potential for spontaneous duct reconnection and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The vasectomy methods of the present invention reduce and/or minimize contact with sensory nerves located on the distal side of the vas deferens, particularly the distal region of the outer vas deferens sheath, so as to minimize nerve damage and the post-surgical pain associated therewith.

  • Patent number: 11272977
    Abstract: An electrically energized medical instrument uses one or more drive cables to both actuate mechanical components of a wrist mechanism or an effector and to electrically energize the effector. Electrical isolation can be achieved using an insulating main tube through which drive cables extend from a backend mechanism to the effector, an insulating end cover that leaves only the desired portions of the effector exposed, and one or more seals to prevent electrically conductive liquid from entering the main tube. Component count and cost may be further reduced using a pair of pulleys that are shared by four drive cables.
