1. A device for detecting organ contents, the device comprising:

  • a body having a detector coupled directly to the body, and at least one detector aperture defined within the body and the at least one detector aperture positioned outside and immediately adjacent the detector, the detector comprising a pair of detection electrodes and a pair of excitation electrodes and the at least one detector aperture sized and shaped to minimize interference that would compromise data obtained by the detector, the at least one detector aperture extending a length from a start of one electrode of the pair of detection electrodes or the pair of excitation electrodes to a start of another electrode of the pair of detection electrodes or the pair of excitation electrodes;

    the body configured for external placement at or near an outside of an organ, but not within or surrounding the organ or within a lumen thereof, and the detector configured to both detect a presence or absence of contents within the lumen of the organ using impedance and to distinguish between any contents detected over time based on conductance data by obtaining first conductance data when solid contents are within the lumen, by obtaining second conductance data when liquid contents are within the lumen, and identifying a difference between the first conductance data and the second conductance data.
