ABSTRACT:
Two probes for tissue impedance measurement each have first and second conductive rings unitarily arranged with an insulative member separating the rings. The conductive rings are coaxially arranged and have individual lead wires connected thereto which extend from one end of the probe for connection to external processing and measuring equipment. One probe is of a size enabling insertion within a blood vessel while the other is for location in an epithelial cavity. In use an alternating test signal is applied to the electrodes of each probe and measurements are taken between the two sets of measuring electrodes determining the impedance of the cavity wall tissue lying between the two probes without passing current through the tissue.
