Abstract

A method and system of monitoring environmental exposure of stents using radiofrequency identification is disclosed.

First claim

What is claimed is:

1. A system for monitoring a stent comprising:
an implantable medical device disposed within a sealed container, wherein the device comprises a bioabsorbable stent crimped over a delivery balloon, wherein the stent comprises a scaffolding including a network of interconnecting structural elements that comprise a polylactide-based polymer;
a sensor disposed within or on the sealed container capable of monitoring a temperature of exposure of the device, wherein the monitored temperature is compared to a temperature tolerance stored on the device and when the temperature tolerance is exceeded, an alert is generated.

2. The system of claim 1 , wherein exceeding the temperature tolerance comprises exceeding a maximum temperature.

3. The system of claim 1 , wherein exceeding the temperature tolerance comprises exceeding a time-temperature tolerance comprising a maximum time above a selected temperature.

4. The system of claim 1 , wherein the container is disposed within a box and the container is a foil pouch.

5. The system of claim 1 , wherein the sensor is integrated with an RFID tag which monitors conditions of exposure and records data.

6. The system of claim 1 , wherein the sensor is positioned less than 8 mm from stent.

7. The system of claim 1 , further comprising an RFID tag capable of storing and transmitting the monitored temperature.

8. The system of claim 7 , wherein the RFID tag is configured to receive data from the sensor.

9. The system of claim 7 , wherein the RFID tag is configured to transmit data to a transceiver which transmits data from the sensor to a storage and processing system.

10. The system of claim 7 , wherein the sensor and RFID tag are communicatively coupled directly or wirelessly.

11. The system of claim 7 , wherein the RFID tag is communicatively coupled with a transceiver and is configured to transmit data from the sensor to the transceiver directly or wirelessly.

12. The system of claim 11 , wherein the transceiver is incorporated into a hand-device.

13. The system of claim 11 , wherein the transceiver is at a location where stents are stored, the location selected from the group consisting of a refrigerator, freezer, within a cargo container, within a truck, within an airplane, and within a train.

14. The system of claim 11 , wherein the transceiver is configured to transmit data it receives to a processing system.

15. The system of claim 14 , wherein the processing system is selected from the group consisting of a desktop, laptop, mainframe, and PDA.
