  • Publication number: 20200030021
    Abstract: Aspects of the present disclosure are presented for a medical instrument configured to adjust the power level for sealing procedures to account for changes in tissue impedance levels over time. In some aspects, a medical instrument may be configured to apply power according to a power algorithm to seal tissue by applying a gradually lower amount of power over to time as the tissue impedance level begins to rise out of the “bathtub region,” which is the time period during energy application where the tissue impedance is low enough for electrosurgical energy to be effective for sealing tissue. In some aspects, the power is then cut once the tissue impedance level exceeds the “bathtub region.” By gradually reducing the power, a balance is achieved between still applying an effective level of power for sealing and prolonging the time in which the tissue impedance remains in the “bathtub region.

  • Publication number: 20200030022
    Abstract: A method for treating hypertrophic cardiomyopathy (HCM) utilizes an RF ablation electrode needle system that has an RF ablation generator, and an electrode needle. The electrode needle is introduced to puncture within myocardium and to reach the hypertrophic area of the interventricular septum. The RF ablation generator is then turned on to implement single-point or multi-point ablation on the hypertrophic area of the interventricular septum, and then the RF electrode needle is withdrawn from the patient.

    Abstract: A catheter tip may be a fabricated as a planar flexible circuit, e.g., via lithography, as having a first planar segment and a second planar segment that includes various electrodes on different sectors that are insulated from each other. The tip may be deformed to have a non-planar configuration, e.g., cylindrical, and then assembled onto a catheter. The catheter may be used to monitor ECG signals and temperature and to precisely deliver ablative energy to tissues via the various electrodes. ECG signals and temperature may be monitored for one sector while ablation energy is being delivered to another sector.

  • Publication number: 20200030026
    Abstract: The present invention is directed to a medical device for providing treatment to diseased tissue and cells. The medical device is configured to ablate a target tissue surface, optionally within a resection cavity, and further deliver a therapeutic that targets diseased (e.g., cancer) cells via a marker whose expression is upregulated by the ablation. The ablation directly kills diseased cells associated with the tissue surface. While some diseased cells evade direct ablation, those cells nevertheless upregulate certain cell surface markers in response to the ablation, even while other, healthy or normal cells do not upregulate expression of the marker in response to the ablation. Devices and methods disclosed herein are used to deliver a therapeutic that uses the upregulated cell surface marker to cause the death of those diseased cells.

    Abstract: A method, including selecting a first maximum radiofrequency (RF) power to be delivered by an electrode within a range of 70W-100W, and selecting a second maximum RF power to be delivered by the electrode within a range of 20W-60W. The method also includes selecting an allowable force on the electrode within a range of 5 g-50 g, selecting a maximum allowable temperature, of tissue to be ablated, within a range of 55° C.-65° C., and selecting an irrigation rate for providing irrigation fluid to the electrode within a range of 8-45 ml/min. The method further includes performing an ablation of tissue using the selected values by initially using the first power, switching to the second power after a predefined time between 3 s and 6 s, and terminating the ablation after a total time for the ablation between 10 s and 20 s.

  • Publication number: 20200030029
    Abstract: Apparatus, systems, and methods of controlling energy delivered to electrodes used in electrically and/or thermally induced neuromodulation are provided to improve neuromodulation. In particular, a catheter treatment device having a control algorithm that regulates current or current density delivered to an electrode is provided. The electrode may maintain a known and consistent electrode contact surface area with the vessel. The control algorithm controls energy delivery to provide consistent current or current density to the treatment site, even though the tissue impedance Z may vary from patient to patient and vessel to vessel, and despite changes in impedance of the treatment, site during the course of the treatment. The controlled delivery of energy can be used to control and maintain placement of the zone of thermal treatment and reduce undesirable energy delivery to unwanted locations near the treatment site.

  • Publication number: 20200030032
    Abstract: The present invention is directed to systems and methods for thermal therapy, especially to detection-guided, -controlled, and temperature-modulated interstitial thermal therapy. Thermal therapy may be used to treat the tissues of a patient. In the case of interstitial thermal therapy, energy is applied to generate heating of the tissue to affect treatment, such as, for example, thermally inducing tissue damage (e.g. thermally-induced tissue necrosis), which may be useful in treating tumors and/or other diseased tissues. Since targets for thermal therapy are internal to the patient, the use of detection guidance may be useful in locating and monitoring treatment of a target tissue.
