    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. The infusion device has a housing, a power source, a therapeutic substance reservoir, a therapeutic substance pump, and electronics.

    摘要： An implantable infusion device includes a positive pressure reservoir, a pump, a flow restrictor, and an outlet. The device includes a first fluid flow path from the reservoir to the outlet, where the pump is downstream of the reservoir, and the outlet is downstream of the pump. The device further includes a second fluid flow path from the reservoir to the outlet, where the flow restrictor is downstream of the reservoir, and the outlet is downstream of the restrictor. The device may also include one or more controllable, MRI-safe valves to select whether fluid is delivered via the first or second flow path.

    摘要： An implantable infusion device for delivering a fluid medication to a patient. The infusion device has an internal bacterial filter positioned between the reservoir and the pump, configured to provide a pathway for fluid to be pulled from the reservoir to the pump, regardless of the orientation of the infusion device. The configuration of the filter provides a fluid pathway from the reservoir to the pump, even in the presence of a gas bubble.
