    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: Peripheral nerve field stimulation (PNFS) may be controlled based on detected physiological effects of the PNFS, which may be an efferent response to the PNFS. In some examples, a closed-loop therapy system may include a sensing module that senses a physiological parameter of the patient, which may be indicative of the patient's response to the PNFS. Based on a signal generated by the sensing module, the PNFS may be activated, deactivated or modified. Example physiological parameters of the patient include heart rate, respiratory rate, electrodermal activity, muscle activity, blood flow rate, sweat gland activity, pilomotor reflex, or thermal activity of the patient's body. In some examples, a patient pain state may be detected based on a signal generated by the sensing module, and therapy may be controlled based on the detection of the pain state.
