ABSTRACT:
A medical device known as an implantable infusion device is configured for implanting in humans to deliver a therapeutic substance such as pharmaceutical compositions, genetic materials, and biologics to treat a variety of medical conditions such as pain, spasticity, cancer, and many other conditions. The infusion device incorporates a motor coil connector and mechanical sealing system between the clean motor compartment and the potentially corrosive pump compartment that provides a reliable electrical connection between the motor coil and the motor drive electronics. The motor coil connector provides for bonding of a very small diameter coil wire to one end of the connector and a highly corrosion resistant connection at the other end of the connector. Additionally, the motor coil connector and mechanical sealing system provides a seal against harmful corrosion materials that could emanate from the pump compartment and reach the motor compartment and cause malfunction of the motor. The infusion device has a housing, a power source, a therapeutic substance reservoir, a therapeutic substance pump, and electronics.
