  • Patent number: 10194980
    Abstract: Methods for treating preventing or decreasing the likelihood of a human patient developing hypertension and associated systems and methods are disclosed herein. One aspect of the present technology, for example, is directed to methods for therapeutic renal neuromodulation that partially inhibit sympathetic neural activity in renal nerves proximate a renal blood vessel of a human patient. This reduction in sympathetic neural activity is expected to therapeutically treat one or more conditions associated with hypertension or prehypertension of the patient. Renal sympathetic nerve activity can be modulated, for example, using an intravascularly positioned catheter carrying a neuromodulation assembly, e.g., a neuromodulation assembly configured to use electrically-induced, thermally-induced, and/or chemically-induced approaches to modulate the renal nerves.

  • Patent number: 10166064
    Abstract: A surgical system and method for fusing tissue are disclosed. The system has an electrosurgical generator capable of delivering electrosurgical power, a surgical instrument electrically connected to the electrosurgical generator and adapted to transfer the electrosurgical power from the electrosurgical generator to a distal end of the surgical instrument, and a power control circuit for controlling the delivery of radio frequency energy to the tissue in contact with the distal end of the surgical instrument. The surgical system is configured to: deliver the radio frequency energy at a non-pulsing power to the tissue for a period of time of 3 seconds or less, wherein the non-pulsing power is held constant, the output current is held under 2 Amperes RMS, and the output voltage is held under 100 Volts RMS, the non-pulsing power further causing the tissue to begin to desiccate and to fuse within the period of time.

  • Patent number: 10130420
    Abstract: A catheter adapted for pulmonary vein isolation, has a distal electrode assembly that can sit stably in an ostium as secured by a plurality of spines and a membrane member. Preshapened and flexible, the spines support the membrane in a concave configuration when the distal electrode assembly approaches the ostium, the spines and membrane member being sized and configured to span across and over the ostium. As the distal electrode assembly is pushed into the ostium, the membrane member elastically deforms, generally turning inside out to expose surface electrodes carried on a contact surface of the membrane member and ring electrodes carried on the spine for contact with the ostium. The membrane member may be inflated. The ring electrodes contact tissue along axial lines of the ostium. The surface electrodes contact tissue along radial lines of the ostium.

    Abstract: A microwave providing device is provided, which is capable of effectively extending the coagulation range of a treatment target tissue by setting the conditions for intermittently providing microwaves. An output controller controls a microwave generator based on a first efficiency of dielectric heating by microwaves with respect to a cumulative radiation period of microwaves radiated intermittently to a treatment target tissue S and a second efficiency of dielectric heating by microwaves with respect to a cumulative radiation period of microwaves radiated continuously to the treatment target tissue so that microwaves are intermittently radiated at least after a reference cumulative radiation period that is set in advance as a cumulative radiation period at which the first efficiency becomes larger than the second efficiency.
