  • Patent number: 9108052
    Abstract: A system and method of controlling the application of energy to tissue using measurements of impedance are described. The impedance, correlated to the temperature, may be set at a desired level, such as a percentage of initial impedance. The set impedance may be a function of the initial impedance, the size and spacing of the electrodes, the size of a targeted passageway, and so on. The set impedance may then be entered into a PID algorithm or other control loop algorithm in order to extract a power to be applied to a treatment device.

  • Patent number: 8974449
    Abstract: An electrosurgical ablation system includes an energy source adapted to supply energy to an energy delivery device. The energy delivery device includes a handle assembly configured to couple a pair of antennas extending from a distal end thereof to the energy source for application of energy to tissue. A power splitting device is operatively associated with the handle assembly and has an input adapted to connect to the energy source and a pair of output channels operably coupled to the respective pair of antennas. A phase shifter is operatively associated with the handle assembly and is operably coupled to the pair of output channels. The phase shifter is configured to selectively shift a phase relationship between the pair of output channels.

  • Publication number: 20150025603
    Abstract: Methods and apparatus are provided for multi-vessel neuromodulation, e.g., via a pulsed electric field. Such multi-vessel neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, the multi-vessel neuromodulation is applied to neural fibers that contribute to renal function. Such multi-vessel neuromodulation optionally may be performed bilaterally.

  • Patent number: 8934988
    Abstract: Hypertension is treated in a patient by implanting an ablation stent in a renal artery of the patient. Energy is transmitted to the ablation stent to induce heating of the ablation stent, which causes ablation of a renal sympathetic nerve present on the outside of the portion of the renal artery comprising the ablation stent. A preferred ablation stent is in the form of an N-turn coil of an electrically conductive wire forming a meander structure. The respective ends of the wire are electrically connected to each other.
