Abstract:
1. A system configured for stimulating tissue internal to a patient's body, said system comprising: at least one sealed elongate housing having a non-circular cross section and configured for implantation via injection in said patient's body, said housing having axial and lateral dimensions selected from the group consisting of: power consuming circuitry carried by said housing including at least one electrode extending externally of said housing, said power consuming circuitry including a capacitor and pulse control circuitry for controlling (1) the charging of said capacitor and (2) the discharging of said capacitor to produce a current pulse through said electrode; a battery disposed in said housing electrically connected to said power consuming circuitry for powering said pulse control circuitry and charging said capacitor, said battery having a capacity of at least one microwatt-hour; an internal coil and a charging circuit disposed in said housing for supplying a charging current to said battery; an external coil adapted to be mounted outside of said patient's body; and means for energizing said external coil to generate an alternating magnetic field for supplying energy to said charging circuit via said internal coil.
