    摘要： Each sensor in one or more pairs of sensors is associated with a particular tissue, for example a first tissue location and a second tissue location respectively. Tissue at a particular tissue location may be solid, for example, muscle tissue, fat tissue, etc., or fluid, for example, blood, fluids associated with edema, etc. The area between the two tissue locations associated with a pair of sensors may comprise solid tissue, fluid tissue, an empty chamber, or combinations thereof. For each pair of sensors in the at least one pair of sensors, a first impedance measurement between the pair of sensors and associated with a first frequency is determined. For each pair of sensors in the at least one pair of sensors, a second impedance measurement between the pair of sensors and associated with a second frequency is determined. A comparison of a ratio of the first impedance measurement at a point in time to the second impedance measurement at a corresponding point in time may be made to determine a volume-related value associated with an area located between the first tissue location and the second tissue location.

    摘要： A method and device are provided that detect and identify a neural signal by type and optionally or automatically provide a signal that affects a nerve carrying the neural signal. A plurality of electrodes is positioned along a nerve and monitors the electrical activity of the nerve. The invented system analyzes the monitored data to determine when the monitored activity can be identified as a known type of bioelectric signal, e.g., a pain nerve signal. The system may optionally attempt to affect, disrupt, diminish, nullify or block transmission of bioelectric signals along the nerve, e.g., by directing electrical energy through an electrode to nullify a bioelectric signal along a pain nerve.
