ABSTRACT:
A dispensing apparatus for placing a settable, fluid-like material in the uterine cavity and moving the material from the uterine cavity into the Fallopian tubes of a female. An elongated disposable dispensing probe carries an expandable member, and a housing connected to the probe has a piston and cylinder structure and a container for storing the material. Material and expansion drive mechanisms are connected to an actuator selectively controlled by an operator. By operating the actuator or control means, the operator causes the material to be dispensed into the uterine cavity while at the same time sealing the cervical entrance to the cavity, and causing the expansion means to expand, substantially filling the uterine cavity and forcing the dispensed material into the canals of the Fallopian tubes. By maintaining actuation of the control means, the operator causes the expandable member to substantially seal the isthmus, that is, the entrance from the uterine cavity into the Fallopian tubes, thus preventing the dispensed material from flowing out of the Fallopian tubes and causing it to remain in the tubes for a period of time sufficient for it to "set-up".
