Abstract: Systems and methods for wireless neural stimulation are presented. A microstimulator comprising a highly magnetic permeable material is implanted in the tissue of a living body. A wearable external controller creates a time-varying magnetic field that extends to the microstimulator in the tissue. The microstimulator re-shapes and boosts the time-varying magnetic field in the area surrounding the microstimulator, causing neural stimulation in the area around the microstimulator. A physician programmer device is also presented that allows a physician to program the wearable external controller.

Abstract: The present disclosure relates to systems and methods for measuring oil/water content in oil-water mixtures, regardless of the salinity of the mixture and regardless of air in the sensor pipe. In some embodiments, the oil content is measured using a dielectric sensor. It is determined whether the oil content is above or below a threshold. If the oil content is above the threshold, the oil content is reported using the measurement from the dielectric sensor. If the oil content is below the threshold, the oil content is reported using the measurement from the eddy current sensor. In some embodiments, which improve performance when there is air in the sensor pipe, two dielectric sensors with different geometries are used instead of the one dielectric sensor.

Abstract: A method and system are provided for determining a condition of a selected region of epithelial and stromal tissue in the human breast. A plurality of measuring electrodes are used to measure the tissue and transepithelial electropotential of breast tissue. Surface electropotential and impedance are also measured at one or more locations. An agent may be introduced into the region of tissue to enhance electrophysiological characteristics. The condition of the tissue is determined based on the electropotential and impedance profile at different depths of the epithelium, stroma, tissue, or organ, together with an estimate of the functional changes in the epithelium due to altered ion transport and electrophysiological properties of the tissue. Devices for practicing the disclosed methods are also provided.

Abstract: Methods and systems for determining a condition of a selected region of epithelial tissue and/or an organ in a body as well as to diagnose disease, susceptibility, premalignancy or cancer and measure response to therapy, introduction of a drug and to assess the margins of a tumor or resection. The methods utilize through the tissue or organ electrical measurements with alternating current using one or more surface or internal electrodes and measuring the electrical response using one or more surface electrodes, preferably in combination with one or more electrodes in direct or indirect contact with epithelium comprising the organ or tissue under test. The methods are also useful in combination with DC measurements on the surface of the organ or tissue under test. Measurement of impedance, admittance, electropotential and dielectric properties is particularly useful, particularly as a function of frequency and position on and in the tissue or organ.

Abstract: Methods and systems are provided for the noninvasive measurement of the subepithelial impedance of the breast and for assessing the risk that a substantially asymptomatic female patient will develop or be at substantially increased risk of developing proliferative or pre-cancerous changes in the breast, or may be at subsequent risk for the development of pre-cancerous or cancerous changes. A plurality of electrodes are used to measure subepithelial impedance of parenchymal breast tissue of a patient at one or more locations and at least one frequency, particularly moderately high frequencies. The risk of developing breast cancer is assessed according to measured and expected or estimated values of subepithelial impedance for the patient and according to one or more experienced-based algorithms. Devices for practicing the disclosed methods are also provided.

A plurality of electrodes are used to measure surface and transepithelial electropotential of tissue, especially breast tissue, as well as surface electropotential and impedance at one or more locations and at several defined frequencies, particularly low frequencies.

Ambient and varying pressure measurements applied to epithelial tissue are also used for diagnosis. Improved diagnosis of tissue condition can be made based on the electrical properties and tissue electrophysiological response to altered ion transport and pressure.

Abstract: A method and system for determining a condition of a selected region of epithelial and stromal tissue, for example in the human breast. A plurality of electrodes are used to measure surface and transepithelial electropotential of breast tissue as well as surface electropotential and impedance at one or more locations and at several defined frequencies, particularly very low frequencies. An agent may be introduced into the region of tissue to enhance electrophysiological characteristics. Measurements made at ambient and varying suction and/or positive pressure applied to the epithelial tissue and/or positive pressure conditions applied to the breast are also used as a diagnostic tool. Tissue condition is determined based on the electropotential and impedance profile at different depths of the epithelium, stroma, tissue, or organ, together with an estimate of the functional changes in the epithelium due to altered ion transport and electrophysiological properties of the tissue.
