  • Patent number: 10285751
    Abstract: An ablation system observes and monitors ablation parameters, including temperature, impedance, and/or the system's own closed-loop response to these ablation parameters. The system comprises a catheter with electrodes and a detection circuitry configured to detect an ablation parameter for each electrode, a controller coupled to the catheter, the controller having a processing unit and a memory storing instructions that, when executed by the processing unit, cause the processing unit to: receive a detected ablation parameter for each electrode from the detection circuitry, determine when a detected ablation parameter violates a defined ablation parameter for each electrode, control a power supplied to each violating electrode to have a reduced power, detect a rate of power reduction for each violating electrode, and stop the power supplied to each violating electrode when a respective detected rate of power reduction exceeds a threshold rate of power reduction.

  • Patent number: 10271892
    Abstract: An electrosurgical system for the treatment of tissue includes an electrosurgical instrument, a source for supplying ionizable gas to said electrosurgical instrument, an electrosurgical generator for supplying high frequency energy to the electrosurgical instrument, and a switch mechanism. The electrosurgical instrument includes one or more conduits and one or more electrodes connected to the electrosurgical generator. The electrosurgical system is movable between at least a first and a second arrangement. The first arrangement is such that one electrode produces a stream of ionized gas exiting one of the conduits, the ionizable gas being capable of the removal of tissue. The second arrangement is such that ionized gas is produced such that it is capable of the coagulation of tissue. The switch mechanism causes the electrosurgical instrument to move between the first and second arrangements.

  • Patent number: 10244955
    Abstract: Systems and methods for noncontact ablation of tissues or materials in/on the body using a luminal catheter and a catheter inserted into the lumen. In one embodiment, the luminal catheter is an ablation catheter and the other catheter is a recording/measurement/positioning catheter. The luminal catheter incorporates a noncontact ablation element such as an ultrasonic transducer. The luminal catheter can be inserted through the skin and into the body (e.g., into the heart) and the recording/measurement/positioning catheter can be inserted into the lumen so that the ablation and recording/measurement/positioning catheters are simultaneously positioned to record/measure the electrical activity of the target tissue and ablate the target tissue without causing the trauma that results from the introduction of additional catheters. Either of the ablation and recording/measurement/positioning catheters can be steerable, and either may incorporate recording/measurement electrodes.

  • Patent number: 10231778
    Abstract: Techniques are disclosed for contemporaneously assessing the success of a renal denervation procedure. One or more characteristics of a patient's heart, such as atrioventricular (AV) interval, PR interval and/or heart rate are monitored during an ablation procedure. A change in the heart characteristic detected during the ablation may indicate successful denervation. Accordingly, successive new locations may be targeted for ablation until a change is detected.
