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 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 fully expand to conform to the shape of the uterine cavity and force the dispensed materials 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 materials from flowing through the canals of the Fallopian tubes and allowing them to remain in the canal for a period of time sufficient for them to set. In the preferred embodiment the expandable member comprises a balloon of sufficient flexibility to conform to the shape of the uterine cavity and to enter and effectively seal the isthmus.
