    摘要: An implantable drug infusion device includes a pump tube for holding a liquid to be pumped. A race is configured to support the pump tube. A roller assembly is configured to compress the tube against the race at one or more points along the path, and the roller assembly includes at least one roller and a hub. A drive assembly drives the roller assembly relative to the tube along the path so as to move the liquid through the tube. A retracting roller is operably connected to the hub and/or one or more adjacent rollers to permit retraction of the roller during installation of the pump tube between the roller and the race.

    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.

    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.
