摘要： 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.

摘要： An implantable drug delivery device includes a pump motor that is asserted by drive currents from a storage capacitor. A programmable rate charge control delivers charging current from a battery to the storage capacitor based upon a programmable charge rate value, a minimum battery voltage value, sensed charging current, and sensed battery voltage. When sensed battery voltage droops to below a threshold value, the charge control reduces the charging rate value until other electrical loads within the drug device have been serviced and battery voltage is restored. The charge control also monitors capacitor voltage and provides a charge complete signal to a motor control, which then connects the pump motor to the storage capacitor to produce a pump stroke. Efficiency of charging is enhanced by controlling the charging at a programmable substantially constant rate.

摘要： An implantable drug delivery device includes a pump motor that is driven by electrical energy from a storage capacitor. At the end of each pump delivery cycle, electrical energy stored in the pump motor is recovered and returned to the storage capacitor, so that it can be used in subsequent delivery cycles.
