Abstract
A method of assessing Fallopian tubal patency includes introducing a distension medium into a patient's uterus, introducing a contrasting medium into the uterus, and observing the contrasting medium, for example, via a hysteroscope, to determine whether the contrasting medium flows into one or both Fallopian tubes. A device for assessing Fallopian tubal patency includes a chamber for receiving contrast media, a flow path through the chamber for delivering distension media to a patient's uterus, and a flow controller for regulating the flow of distension media to the patient's uterus. The flow path is configured to permit flow of contrast media from the chamber into the flow path.
