1. An implantable drug delivery device having a performance data reporting feature, comprising:
- (a) a housing;
(b) a drug reservoir positioned in the housing and configured to contain a therapeutic substance;
(c) a pump coupled to the drug reservoir;
(d) electronics positioned in the housing and coupled to the pump and a power source, the electronics including a memory, the memory containing pump performance acquisition instructions;
(d) a flow control module coupled to the memory for controlling the flow of the therapeutic substance directed from the drug reservoir through an infusion port by the pump;
(e) a telemetry module coupled to the memory;
(f) at least one monitoring module coupled to the memory that monitors at least one pump operation variable according to the pump performance acquisition instructions to produce performance data; and
(g) at least one reporting module coupled to the memory, the reporting module configured to activate the telemetry module to report performance data.

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.

11. An implantable drug delivery device having a data reporting feature, comprising:
-
(a) a housing;
(b) a drug reservoir positioned in the housing and configured to contain a therapeutic substance;
(c) electronics including a memory for storing data and programming positioned in the housing, the electronics configured to control the flow of the therapeutic substance from the drug reservoir through an infusion port;
the electronics configured to monitor the flow of therapeutic substance, the electronics further configured to communicate via two-way telemetry with an external programmer so that information for use in evaluating the performance of the implanted drug delivery device can be reported and programming on the device can be modified; and
(d) a sensor for use in providing 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 (12, 13, 14, 15)

16. An implantable drug delivery device with data reporting capabilities, comprising:
-
(a) a housing;
(b) a flow means for storing and delivering a therapeutic substance, the flow means positioned in the housing;
(c) a catheter fluidly coupled to the flow means, the catheter configure so that in operation the therapeutic substance can be directed to the desired portion of the patient;
(c) a control means for controlling the flow means, the control means configure to provide two-way communicating with an external programming means, the control means further configured for reporting data to the external programming means; and
(d) a sensing means for providing feedback to the control means so that in operation the control means can control the therapeutic substance means based on programming received from the external programming means and feedback received from the sensing means. - View Dependent Claims (17, 18, 19, 20)
