Abstract

See full text

A fluid dispensing instrument and method for placing a drug material into the canals of the Fallopian tubes of a female. The instrument has a housing carrying a piston and cylinder assembly. An elongated flexible tubular probe attached to the housing carries an expandable sleeve. The piston and cylinder assembly is operable to fully collapse the sleeve prior to insertion through the cervical opening into the uterine cavity. After the sleeve is inserted into the uterine cavity, an ampulla storing the drug material is loaded into the instrument. The piston and cylinder assembly is then actuated to initially partially expand the sleeve. Operation of the piston and cylinder assembly moves a plunger into the ampulla to dispense the drug material into the uterine cavity above the partly expanded balloon. The sleeve is then fully expanded to move the drug material from the uterine cavity into the canals of the Fallopian tubes.
