ABSTRACT:
An apparatus for locating rectovaginal fistulas, including a cannula of a predetermined length, open-ended on its first end having an inflatable balloon portion on its closed second end; the first end of the cannula further comprising a cone portion along its length to seal up against the exterior wall entrance to the rectum, after the second end of the cannula has been inserted into a patient's rectum; a fluid line is positioned within the cannula space for inflating the balloon after the cannula is in place in the rectum to seal the distal end of the rectum passage; a plurality of openings are provided along the wall of the cannula between the balloon and the cone at the first end of the cannula; a colored gel or other fluid insertable into the cannula to the extent that the gel or other fluid escapes the cannula through the openings and enters the void between the cannula and the wall of the rectum, with sufficient gel or other fluid entering the void so that gel or fluid would seep into any fistulas present and would be visually identifiable in the vagina for treatment.
