In October, I saw a mock-up prototype of the Elan/Bioject glucose monitoring system. There are 2 pieces: a "patch" and a monitor that looks like a wrist watch.

The "patch" is a plastic platform with an adhesive surface, which is designed to be stuck to the chest of the patient. A second piece is hinged on one end of the patch and comes down, snapping into place. This causes a tiny needle to be inserted into the skin. This needle is what is used to sample the interstitial fluids. A radio signal is sent to the wristwatch, storing history and displaying the current blood glucose level.

The analysis of interstitial fluids is apparently a very accurate method to determine blood glucose. However, it is delayed about 10 minutes. This delay is considered to be a non-issue.

Art, I looked at the information available about Integ. The main difference that I can see is that the Bioject JV product will produce continual monitoring, while Integ's product will only do "on demand" monitoring. The main advantages of the JV tools will be:

- the ability to store history
- the ability to know whether blood glucose is currently rising or falling. It would require very frequent "on demand" testing to see such a trend.

When I described this to my brother, who is a physician, he immediately jumped on the possibility of using the continual monitoring as the input needed to drive an automatic insulin pump. He is excited about the potential to fine-tune blood sugar levels in this way.

Happy Holidays to all,
Marc Kahn
