Abstract

A closed loop system for monitoring drug dose, intake and effectiveness includes a pill dispenser in data communications with at least one implantable medical device. The system is preferably implemented in a web-enabled environment in which a remote data center communicates with the implantable devices (IMDs) in a patient via a programmer or the pill dispenser. Th data center includes high speed computers and databases relating to patient history and device information. A physician or clinician may access the remote data center to review and monitor the IMDs remotely. More specifically, the IMDs are adapted to chronically monitor the pill dispenser to thereby log and document drug dose, patient compliance with prescriptive regimens and as well to monitor drug efficacy in the patient. The system further provides a dynamic drug management system, compatible with a web-enabled interactive data communication environment, that accurately monitors dose and specific drug effectiveness in a patient to enhance patient care.

Claims

1. An interactive remote drug dose and physiologic response monitoring system in a patient wherein at least one IMD is adapted to communicate with a drug dispenser to identify when a pill is removed from the pill dispenser and taken by a patient, the monitoring system comprising:

a pill dispenser;

an IMD in wireless communications with the pill dispenser; and

communications means to transfer signals from the pill dispenser to the IMD;

the IMD being implanted in a patient under a prescriptive regimen to take pills from the dispenser wherein the IMD monitors the patient'"'"'s physiological signs for compliance with a prescriptive regimen, and check drug interaction in the patient.

2. The monitoring system of claim 1 wherein said pill dispenser includes a piezoelectric layer structured to send signals when subjected to minor pressure.

3. The monitoring system of claim 1 wherein said communications means includes a telemetry system to transfer signals from the pill dispenser to the IMD.

4. In a wireless communications system a pill dispenser and at least one IMD having data exchange means pertaining to clinical information based on a drug dose regimen on which a patient having the IMD is placed wherein the clinical data exchange is also routed to various remote centers connected via a wireless link system, the communications system comprising:

the pill dispenser and the at least one IMD;

a programmer or an interface medical unit;

a remote data center having high speed computer resources including databases for string and retrieving medical data; and

a physician station;

said pill dispenser and said programmer having telemetric communications with the at least one IMD wherein clinical data from the IMD relating to the pill dispenser and the drug dose are transmitted to the databases at the remote data center via said programmer or said pill dispenser to enable a physician at the physician station to remotely access the clinical data at the databases.

5. The communications system of claim 4 wherein said at least one IMD includes a plurality of IMDs, implanted in various parts of the patient, having intracorporeal communications therein and further being in data communications with said programmer and said pill dispenser.
