Abstract
A dispensing instrument and method for simultaneously injecting fluids, as drug materials, into the canals of the Fallopian tubes of a female primate. The dispensing instrument has a body accommodating a container for storing the drug materials. An elongated member carrying an expandable balloon is mounted on the body. A sheath encloses the elongated member and balloon. The sheath is attached to a tubular needle which extends through the elongated member. A releasable lock holds both the sheath and needle in assembled relation with the body. A plunger moves the container into dispensing relation with the needle whereby the fluid in the container is carried via the needle into the uterine cavity. The fluid flows into the canals of the Fallopian tubes. The expandable member is subjected to fluid under pressure. The fluid is continuously monitored to maintain a continuous and uniform low pressure on the expanded balloon.
