  • Publication number: 20250221762
    Abstract: Methods and devices for non-thermal treatment of endometriosis. The non-thermal treatment of endometrial lesions results in electroporation of the endometrial cells, and ultimately necrosis of the lesion. Lesions are identified and electric field parameters determined to substantially remove all of the endometrial cells in the target lesion. Application of the electric field to the lesion creates a treatment zone where the cells necrose, leaving the cellular matrix mostly undisturbed. Devices include a generator capable of applying an electric field to an endometrial lesion through one or more electrodes.
