Birth control method and device employing electric forces
First Claim
1. The method of birth control which comprises producing an electrical force within and about the cervical canal for preventing migration of male sperm through the cervical canal into the unterine cavity, said method comprising inserting a birth control device formed by a set of spaced-apart opposed low voltage electromotive force producing electrodes within at least the opening to the cervical canal and retaining it in place over extended periods of time and supplying an electromotive force of known voltage across the electrodes from an indepedent source of electric potential.

Abstract
A method and device for birth control which comprises producing an electrical force within the cervical canal of a female for acting on male sperm and preventing migration of the sperm through the cervical canal and into the uterine cavity. The electrical force is provided by a self-contained, sealed battery capable by itself of producing an electromotive force and is inserted within the cervical canal and retained therein over extended periods of use. The device is designed such that it does not impede the free flow of menstrual and other discharges through the cervical canal and is fabricated with or covered by biologically inert material so that it can be retained in place in the cervical canal for indefinite periods as long as desired by the user for birth control purposes. The device is provided with anchoring means which are designed to engage the wall of the cervical canal for securely holding the device in place within the cervical canal with the electric force producing electrodes so positioned as to be exposed to fluids passing through the cervical canal.

- 20. A birth control device comprising a set of low voltage, opposed electromotive force producing eletrodes designed and proportioned to be inserted in proximity to the cervical canal of a female human or animal for producing an electrical force within the cervical canal for acting on male sperm and preventing migration of the sperm through the cervical canal and into the uterine cavity, means for supplying an electromotive force of known voltage across the electrodes from an independent source of electric potential, and means for fixing the birth control device in proximity to the cervical canal, said birth control device including the means for fixing the same being fabricated from or coated by materials which are biologically inert and safe for physical contact with human and animal tissue over extended periods of time.
