Abstract
The present invention provides for an improved surgical technique of the type which uses a Nd:YAG laser to treat the uterus while the uterus is kept distended by the flow of saline into the uterine cavity. The improvement comprises the hysteroscopic insertion of a retrievable ostial plug into the tubal ostia of each fallopian tube so that the saline does not flow through the fallopian tubes during the period of time in which the laser is used to treat the uterus. At the conclusion of the laser treatment, the retrievable ostial plugs are hysteroscopically retrieved and withdrawn. The invention also provides for a specific retrievable ostial plug for use in the procedure. The plugs are specifically adapted for hysteroscopic insertion and withdrawal from the tubal ostia.
