Abstract
A hysterography device is provided which avoids the various disadvantages inherent in prior art devices, namely patient discomfort, incomplete seal-off of the cervical canal, complexity, and lack of provision for introduction of catheters or filberoptic devices into the uterine cavity through a sterile conduit. A handle having a conduit therein is provided for the introduction of catheters, coaxial catheter systems, fiberoptic devices, and contrast media. A cup at the distal end of the handle is vacuum or suction seated on the cervix of the patient to seal contrast media in the cervical canal. A movable cone may be provided for an enhanced seal. Preferably, the cup and the handle are soft and flexible plastic allowing for better seating on the cervix and better operator manipulation. A variety of cup shapes and sizes may be used. Vacuum suction in the cup may be provided by an independent flexible conduit. A method of use of such device is provided.
