Implantable infusion device |
摘要 |
An improved implantable infusion device for delivering precisely regulated doses of fluid into the body of a patient is disclosed. The device utilizes a resilient non-compliant pump bellows that is directly coupled by a gear train to a motor. The bellows is biased toward the expanded position and this factor, combined with the mechanical inertia of the gear train, substantially eliminates the danger of an overdose of infusate being released into the patient.
