  • Patent number: 10864039
    Abstract: The invention is a system for monitoring and controlling tissue ablation. The system includes a controller configured to selectively control energy emission from an electrode array of an ablation device based on ablation feedback received during an ablation procedure with the ablation device. The controller is configured to receive feedback data from one or more sensors during the ablation procedure, the feedback data comprising one or more measurements associated with at least one of operation of the electrode array of the ablation device and tissue adjacent to the electrode array. The controller is further configured to generate an ablation pattern for controlling energy emission from the electrode array of the ablation device in response to the received feedback data.

  • Patent number: 10835311
    Abstract: An electroporation apparatus and the method of using same are provided. The apparatus allows for the ablation of an area of tissue of arbitrary volume. The apparatus includes a plurality of conductive electrodes attached to a base plate and electrically connected to a pulse generator to allow individual electrical actuation of the electrodes. In use, the electrodes are inserted into an area of tissue to be ablated, such that the electrodes are in a first position. Predetermined ones of the electrodes are then activated to ablate tissue surrounding the activated electrodes, while leaving other ones of the electrodes un-activated. The electrodes are then moved to a second position which is different than the first position, and predetermined ones of the electrodes are then activated to ablate tissue surrounding the activated electrodes, while leaving other ones of the electrodes un-activated.

  • Publication number: 20180014880
    Abstract: The present invention relates to an electrosurgical system including an electrosurgical device to be delivered to a wound site to provide chronic wound treatment. The device can be used during a wound care procedure to provide targeted energy at a wound site for reducing the accumulation of biofilm present and removing necrotic tissue and debris so as to promote, stimulate, and stabilize the wound healing process. The device can further be used during a surgical procedure, such as preparation for an orthopedic implant, in which the device is configured to selectively coagulate one or more pockets prepared within bone tissue for holding an implant so as to prevent or stop fluid accumulation (e.g., blood from vessel(s)) as a result of the implant preparation.
