Abstract: An apparatus includes a bottom panel with a transparent region and ceramic sidewalls affixed to the bottom panel to form a container. Electrodes are disposed on the outer surface of the sidewalls at positions selected so that when a sample is positioned in the container, applying a voltage between the electrodes induces an electric field through the sample. Electrical conductors provide contact with the electrodes. All the components are sized and shaped to facilitate positioning of the container on the stage of an inverted microscope so that when the sample is positioned in the container, light emanating from a light source is free to travel along an optical path that passes through the sample, through the transparent region, and into the objective of the inverted microscope. The electrodes and conductors are positioned with respect to the transparent region so as not to interfere with the optical path.

Abstract: A transducer array for use in tumor-treating fields (TTFields) therapy is particularly suited for use in treating abdominal or thoracic cancers. The transducer array has features that increase its flexibility and adhesion to the patient's skin, including a branching configuration and a correspondingly branching top covering adhesive-backed layer. Additionally, a skin-level adhesive layer is provided beneath the flex circuit to which the electrode elements are attached, to help ensure thorough, lasting adhesion of the transducer array to the patient's skin over the course of treatment.

Abstract: This application discloses configurations for arranging transducer arrays on a person's head to impose tumor treating fields (TTFields) in the brain at field strengths that are as uniform as possible throughout the entire brain. In some embodiments, L-shaped sets of electrodes are positioned near the right and left ears, each with a horizontal arm above the ear and a vertical arm behind the ear. Optionally, these embodiments may be combined with a second pair of electrodes positioned on top of the head and behind the neck. In other embodiments, one pair of electrodes is positioned above the right ear and on the left/rear portion of the neck; and a second pair of electrodes is positioned above the left ear and on the right/rear portion of the neck. These configurations improve the uniformity of the electric fields imposed throughout the brain, and are particularly useful for preventing and/or treating metastases.

Abstract: Alternating electric fields (e.g., TTFields) may be applied to a subject's body using electrode assemblies, each of which includes a plurality of graphite sheets (or sheets of another conductive anisotropic material) that are positioned adjacent to, but not touching, each other. One or more electrode elements are disposed in electrical contact with each of the graphite sheets. Strips of electrically insulating and thermally conductive material are disposed between the graphite sheets, and these strips are positioned in thermal contact with the adjacent graphite sheets. The graphite sheets facilitate the passive spreading of heat within the confines of any given sheet. And the strips of material allow the passive spreading of heat to continue beyond the confines of any given sheet without compromising inter-sheet electrical isolation.

Abstract: A method of treating acute respiratory distress syndrome (ARDS) in a subject by applying an alternating electric field (AEF) to a region of the subject's torso. The ARDS may be caused by sepsis, viral infection, bacterial infection, near-drowning, chemical inhalation, acute pancreatitis, and chest injury. The viral infection may be COVID-19 or long covid. The ARDS may be identified using the Berlin Definition.

Abstract: A subject can be treated with an alternating electric field (e.g., TTFields) by applying the alternating electric field to a target region, and measuring nerve or muscle activity that is generated by the subject's body in response to the alternating electric field. The course of treatment is then modified based on the measured nerve or muscle activity to reduce or eliminate electrosensation. The nerve or muscle activity can be nerve activity that is measured, e.g., based on an evoked compound action potential (ECAP). In some embodiments, the modification is implemented by adjusting an amplitude or frequency of the alternating electric field. In other embodiments, the modification is implemented by applying an electrical signal to the subject's body, where the electrical signal is configured to reduce electrosensation.
