Method for wirelessly monitoring implanted medical device
First Claim
1. A method for monitoring the status of a medical device implanted in a patient, the method comprising:
- implanting in a patient a medical device which comprises (i) a substrate in which two or more reservoirs are located, with each covered by a reservoir cap, (ii) a drug or sensor located in the reservoir, (iii) a power source and actuation electronics operable to melt each reservoir cap and thereby expose the drug or sensor to an environment at the site of implantation in the patient, and (iv) a telemetry system; and
using said telemetry system to wirelessly transmit to a remote controller data about the condition of the power source and/or data about which reservoirs have been or have yet to be activated to release the drug therefrom or to expose the sensor therein.

Abstract
A method is provided for monitoring the status of a medical device implanted in a patient. The method includes the steps of implanting in a patient a medical device which comprises (i) a substrate in which two or more reservoirs are located, with each covered by a reservoir cap, (ii) a drug or sensor located in the reservoir, (iii) a power source and actuation electronics for disintegrating or permeabilizing the reservoir cap, and (iv) a telemetry system; and then using said telemetry system to wirelessly transmit to a remote controller data about the condition of the power source and/or data about which reservoirs have been or have yet to be activated to release the drug therefrom or to expose the sensor therein.

7. A method for monitoring the status of a medical device implanted in a patient, the method comprising:
-
implanting at a site in a patient a medical device which comprises (i) a substrate in which two or more reservoirs are located, with each covered by a reservoir cap, (ii) a drug formulation disposed in the two or more reservoirs, (iii) a power source and actuation electronics operable to melt each reservoir cap, thereby permitting the drug to be released from the medical device to the patient, and (iv) a telemetry system; and using said telemetry system to wirelessly transmit to a remote controller data about the condition of the power source and/or data about which reservoirs caps have been or have yet to be disintegrated, melted, or otherwise ruptured. - View Dependent Claims (8)

9. A method for monitoring a medical device implanted in a patient, the method comprising:
-
implanting in a patient a medical device which comprises (i) a silicon substrate in which two or more reservoirs are located, with each covered by a reservoir cap comprising a metal film, (ii) a drug or sensor located in the reservoir, (iii) a power source and actuation electronics operable to cause a rise in temperature of each reservoir cap to disintegrate or melt each reservoir cap and thereby expose the drug or sensor to an environment at the site of implantation in the patient, and (iv) a telemetry system; and using said telemetry system to wirelessly transmit to a remote controller data about the condition of the power source and/or data about which reservoirs have been or have yet to be activated to release the drug therefrom or to expose the sensor therein.
