1. An implantable drug delivery system having a data delivery feature, comprising:
- an external device;
a housing;
a drug reservoir positioned in the housing and configured to contain a therapeutic substance;
an infusion port in fluid communication with the drug reservoir;
a pump configured to direct the therapeutic substance from the drug reservoir to the infusion port; and
electronics coupled to pump and configured to control the flow of therapeutic substances from the drug reservoir to the infusion port, the electronics including a memory configured to store performance information and programming, the electronics further configured to monitor the flow of the therapeutic substance, wherein the electronics is configured to be in bi-directional communication with the external device and to provide performance information from the memory to the external device and to receive changes to the programming in the memory from the external device.

Abstract
Disclosed is a method and apparatus for automatically adjusting drug infusion rate to optimize treatment therapy. The implantable medical device can communicate with a database or algorithm controlled by a caregiver or physician. Thus, the caregiver may request a therapy change (e.g., infusion rate versus time, pump clock settings, etc.) or a therapy management module may automatically activate the therapy change at some future time for convenience, or for technical or clinical reasons.

12. An implantable drug delivery device, comprising:
-
a housing; a drug reservoir positioned in the housing and configured to contain a therapeutic substance; an infusion port in fluid communication with the drug reservoir; a pump in the housing, the pump configured to direct the therapeutic substance from the drug reservoir to the infusion port; electronics coupled to the pump and configured to control the flow of therapeutic substances from the drug reservoir to the infusion port, the electronics including a memory configured to store performance information and programming, the electronics further configured to monitor the flow of the therapeutic substance and to communicate with an external programmer via a network so that performance information of the implanted drug delivery device can be reported and programming on the device can be modified based on the performance information; and a sensor configured to in provide feedback to the electronics;
wherein the electronics is configured to accept programming via telemetry so as to control whether the therapeutic substance is delivered through the infusion port based on the feedback received from the sensor. - View Dependent Claims (13, 14, 15, 16)
