  • Osmotic beneficial agent delivery system
    Publication number: 20030083647
    Abstract: An osmotic beneficial agent delivery system includes an implantable osmotic delivery device and a catheter for delivery of the beneficial agent from the delivery device to a delivery location. The beneficial agent delivery system includes a catheter and a docking station which are implanted in the patient with a distal end of the catheter positioned at a delivery site. The catheter and docking station are left in place while an implant containing the beneficial agent is removably connected to the catheter at the docking station and can be replaced as needed. The docking station provides a connection between a catheter and the implant allowing the implant to be replaced periodically while the catheter and the docking station remain in place.
