Energy delivery probe with independently activatable electrodes for ablation
A recently filed patent (Publication Number: US20230263570A1) describes a method and system for treating tissue in a patient using electrical energy. The method involves inserting a trocar into or near the target tissue and placing an energy delivery probe with a first electrode through the trocar. A second electrode is placed near the target tissue, and both electrodes can be selectively activated. An electrical energy source is then activated, delivering electrical energy from either the first or second electrode. The electrical energy source is designed to switch activation between the electrodes, allowing for the delivery of electrical energy from the first electrode to the second electrode.
The system for treating tissue described in the patent includes a trocar, an energy delivery probe with a first electrode, and a second electrode. The trocar is designed to be placed into or near the target tissue and has a sharp distal tip. The energy delivery probe is coaxially placed through the trocar, with its distal tip extending beyond the trocar's tip. The second electrode is positioned near the target tissue, and both electrodes can be independently activated. An energy source is coupled to the electrodes and programmed to switch activation between them, enabling the delivery of electrical energy from the first electrode to the second electrode.
The electrical energy delivered in both the method and system can be biphasic or monophasic pulses. The energy can be configured to non-thermally ablate the target tissue or irreversibly electroporate it. Additionally, the trocar and energy delivery probe may include depth markers to assist in accurate placement.
This patent presents a method and system that utilize electrical energy for treating tissue in a patient. By selectively activating electrodes and switching the delivery of electrical energy, the method and system offer potential benefits in tissue treatment. The use of depth markers and the option for non-thermal ablation or irreversible electroporation further enhance the precision and effectiveness of the treatment.
