ABSTRACT:
An apparatus for injection of dye or contrast medium into a uterine cavity. An elongated member having a first and a second end and an intermediate portion has a liquid impervious expandable tube disposed around it and is sealed on each end thereof to the exterior thereof. A first fluid passageway extends from one end of the elongated member to a barrier and another fluid passageway extends from the other end of the elongated member to the barrier. A first opening in the elongated member allows fluid communication between the first passageway and the inside of the balloon tube and a second opening in the elongated member provides fluid communication between the second fluid passageway and the inside of the balloon tube. The second opening is substantially smaller in cross-sectional area than the first opening whereby fluid pressure applied to the first passageway will remain substantially higher than the pressure in the second fluid communication passageway, whereby fluid pressure within the tube will cause it to expand to seal against the inner wall of the uterine cavity, while at the same time fluid will flow sequentially from the first fluid communication passageway, through the first opening, through the expanded balloon tube, through the second opening, through the second communication passageway and out through a discharge opening structure on one end of the second fluid communication passageway.
