1. Apparatus for monitoring motility and/or peristalsis in a tubular organ which transports its contents, comprising:

  • a catheter sized to fit within the tubular organ,a plurality of electrodes positioned along the outside of the catheter in electrical contact with the organ at longitudinally displaced points there along,first channel means for measuring the impedance of the organ between a pair of said electrodes;

    a plurality of additional channel means for making multiple, substantially simultaneous impedance measurements between electrode pairs representing the impedance of the organ at longitudinally displaced positions along the organ; and

    means for indicating the longitudinal displacement along the organ of impedance measurements made by the plurality of channel means which are characteristic of peristaltic content transport.
