System and Method of Electric-Induced Acoustic Tomography for Electrotherapy Monitoring
20190290903 · 2019-09-26 ·

A method and system for monitoring an electrotherapy treatment applied to a subject in need of such therapy. An ultrasound transducer array is positioned adjacent a tissue of the subject to which the electrotherapy treatment is to be applied. The electrotherapy treatment is administered to the tissue as a plurality of ultra-short electric pulses which generate an electric field in the vicinity of the tissue. The ultrasound transducer array detects acoustic signals which are induced by the electric field. The detected acoustic signals are then used to construct tomographic images which represent the electric field generated by the electrotherapy treatment during real-time.

Methods and devices for stimulating an immune response using nanosecond pulsed electric fields

Nanosecond pulsed electric field (nsPEF) treatments of a tumor are adjusted based on a size and type of the tumor to stimulate an immune response against the tumor and other tumors in the subject. Calreticulin expression on tumor cells can be detected to confirm treatment. An immune response biomarker can be measured, and further nsPEF treatments can be performed if needed to stimulate or further stimulate the immune response. Cancers that have metastasized may be treated by directly treating a tumor that is most accessible. The treatment can be combined with CD47-blocking antibodies, doxorubicin, CTLA-4-blocking antibodies, and/or PD-1-blocking antibodies. Electrical characteristics of nsPEF treatments can be based on the size, type, and/or strength of tumors and/or a quantity of tumors in the subject.

DEVICES AND METHODS FOR HIGH FREQUENCY ELECTROPORATION

The present invention provides systems, methods, and devices for electroporation-based therapies (EBTs). Embodiments provide patient-specific treatment protocols derived by the numerical modeling of 3D reconstructions of target tissue from images taken of the tissue, and optionally accounting for one or more of physical constraints or dynamic tissue properties. The present invention further relates to systems, methods, and devices for delivering bipolar electric pulses for irreversible electroporation exhibiting reduced or no damage to tissue typically associated with an EBT-induced excessive charge delivered to the tissue.

Device for inactivating bacteria on the surface of the stratum corneum layer of skin

The present application relates to a device for the electroporation of bacterial cells in or on a surface of the Stratum corneum layer of a person's skin. It comprises electrodes positionable in the vicinity of said surface; a generator to supply a voltage to the electrodes to generate an electrical field having a strength in the order of 25 to 35 KV/cm at said surface of the Stratum corneum layer to inactivate bacterial cells in or on said surface. The electrodes are configured so that the strength of the electrical field reduces as a function of the depth of penetration into the skin from 25 to 35 KV/cm at said surface to 3 KV/cm or less at a depth of penetration that does not exceed 15 microns. The electrical field generated by the device will have sufficient strength to inactivate bacteria cells present on the stratum corneum while at the same time this electrical field is not strong enough to appreciable effect living skin cells in the epidermis below the stratum corneum or at the interface between the stratum corneum and the epidermis.
