Abstract

Abstract A dispensing instrument with supported balloon (46) having a dispenser operable to place drug material into the uterine cavity and an expandable balloon (46) cooperating with support structure (59) operable to move the drug material from the uterine cavity into both canals of the Fallopian tubes. The instrument housing carries a piston/cylinder assembly. The balloon (46) is attached to a flexible tubular probe (43) mounted on one housing end. The piston/cylinder assembly is operable to fully collapse the balloon (46). After the balloon (46) is inserted through the cervical opening into the uterine cavity, a drug ampulla is loaded into the instrument. The piston/cylinder assembly is actuated to initially expand the balloon (46) and move a plunger into the ampulla to dispense drug material into the uterine cavity. The balloon (46) is then fully expanded to move the drug material into the canals of the Fallopian tubes. The balloon support structure (59) prevents the balloon (46) from expanding back through the cervical opening into the vaginal passage. The support structure (59) is a monofilament nylon (61, 62, 63, 64) arranged in intersecting latitudinal and longitudinal directions about a lower ballon (46) portion.
