Abstract
An intrauterine catheter attached to a fluid dispensing unit for injecting fluids, as drug materials, into the canal of the Fallopian tube. The catheter is an elongated tubular member having a pair of isolated tubes. A first of the tubes has an expandable balloon on its outer end for substantially completely filling a uterine cavity when expanded. The dispensing unit has a housing with chambers. Containers storing the drug material and fluid are located in the chambers. The containers are collapsible hollow bodies which are pierced by needles which carry the fluids to the tubular member. Plungers collapse the containers to drive the needles through the container walls whereby the fluid in the containers is discharged into the tubes of the catheter. A hand operated actuator is operable to sequentially dispense fluid from a first container into the first tube and then a second container into the other tube.
