ABSTRACT:
Apparatus for measuring the electrical impedance of a tissue sample comprises a probe and a sheath comprising an elongated tubular body having one closed end and one open end providing an internal cavity. The sheath is composed of a material which when contacted with a tissue sample is capable of providing a conductive path through the sheath between the electrodes and the tissue sample. The resistivity of the material forming the sheath when contacted with the tissue sample is greater than the resistivity of the tissue sample. The probe is received within the internal cavity of the sheath. The sheath is impervious to bacteria and viruses.
