  • Method and Apparatus for Automatically Modifying Delivery Profile of Drug Delivery System
    Publication number: 20080177254
    Abstract: The present invention relates to an implantable drug delivery device which includes a fluid drug reservoir, a catheter, a controllable fluid transfer device, e.g., a pump or valve, and a drug delivery control means. The control means in accordance with the invention is configured to initially clear a first, or old, drug from the device based on the content of the Current Profile data containing a first, or old, delivery profile. After the old drug is cleared, then the control means automatically modifies the Current Profile data to match a second, or new, delivery profile for controlling delivery of a second, or new, drug.

  • Drug Delivery Apparatus and Method for Automatically Reducing Drug Dosage
    Publication number: 20080172044
    Abstract: A drug delivery device which includes a fluid drug reservoir, a catheter, a controllable fluid transfer device, e.g., a pump mechanism or valve, and a drug delivery control means. The drug delivery control means comprises a controller, e.g., a microprocessor or microcontroller which is operable to automatically reduce the rate of drug delivery over a certain reduction interval (e.g., multiple days) from an initial dosage value to a final dosage value.
