ABSTRACT:
A method and apparatus for recognizing tissue types measures at least two separate and distinct properties of a tissue specimen using a probe tip containing electrodes coupled to circuitry that applies a measuring current and obtains values of electrical properties of the tissue such as conductivity and potential difference. An algorithm then uses the values to determine the tissue's type and condition.
