Implantable device for locating drug users

Abstract

A medical implant including a drug sensor and a global positioning system (GPS) module connected to a wireless network. The GPS module sends a location of the patient and optionally information of when patient uses an illegal drug when the sensor detects the drug within the patient's bloodstream.

What is claimed is: 
     
         1 . A medical device comprising:
 a global positioning system module connected to a wireless network; and   a sensor operable to sense change in an animal's blood composition when the animal consumes a drug, wherein   when the sensor senses the change in the animal's blood composition, a location message comprising a location of the medical device is sent over the wireless network to a remote computer.   
     
     
         2 . The medical device of  claim 1 , further comprising a diaphragm and a catheter extending from the diaphragm, wherein the sensor is attached to the catheter. 
     
     
         3 . The medical device of  claim 1 , wherein the wireless network is a telecommunications network. 
     
     
         4 . A method of determining a location of a patient that consumes a drug comprising the steps of:
 providing a medical device comprising a drug sensor and a global positioning system module connected to a wireless network;   implanting the medical device into the patient so that the drug sensor is disposed within a blood layer of the patient;   detecting a consumption of a drug by the patient via the drug sensor; and   sending a location message comprising a location of the medical device over the wireless network to a remote computer.   
     
     
         5 . The method of  claim 4 , wherein the medical device further comprises a diaphragm and a catheter extending from the diaphragm, wherein the catheter is threaded into an artery of the patient. 
     
     
         6 . The method of  claim 4 , wherein the wireless network is a telecommunications network, the remote computer is a phone and the location message is displayed on the phone as a text message. 
     
     
         7 . A system of determining a location of a patient that consumes a drug comprising:
 a medical device implanted in a patient's body, wherein the medical device comprises a global positioning system module connected to a wireless network and a sensor operable to sense change in an animal's blood composition when the animal consumes a drug; and   a remote computer connected to the wireless network, wherein the remote computer comprises a processor and a memory, wherein   when the sensor senses the change in the animal's blood composition, a location message comprising a location of the medical device is sent over the wireless network to the remote computer.   
     
     
         8 . The system of  claim 7 , wherein the wireless network is a telecommunications network, the remote computer is a phone and the location message is displayed on the phone as a text message. 
     
     
         9 . The system of  claim 7 , wherein the medical device further comprises a diaphragm and a catheter extending from the diaphragm, wherein the catheter is threaded into an artery of the patient. 
     
     
         10 . The system of  claim 7 , wherein the sensor detects an opiate within the blood stream.
