Who's ever heard of the GlucoDay® S semi-invasive continuous glucose monitor?
I didn't think so. I picked up a hint from a medblogger's footnote. Then I found it described over at DiabetesMall, although the link to the product on the manufacturer's site doesn't seem to be working.
That manufacturer would be A.Menarini Diagnostics, Italy's largest pharmaceutical R&D company, which released the GlucoDay across Europe a year ago (or two? -- I've had no luck getting hold of them despite attempted introductions). The GlucoDay is apparently the first system in the world based on a "microdialysis" technique to obtain the CE marking for the Medical Device Directive, required to market any product in the European Union. But don't get too excited; I read the fine print, and it's only designated for clinical use, "worn by the subject for a 48-hour period."
So why am I bringing this up? Well, I happen to love innovation, and like Kerri, I'm finding the Guardian MiniLink sensor to be rather uncomfortable. Meanwhile, I didn't like using the DexCom much at all. I'm feeling ready for something less invasive. So these guys had me at semi-invasive. But what the heck does that mean?
Apparently the only thing going in your body with the GlucoDay is a "microfiber" inserted under the skin, as part of a small "biosensor."

A New Square Patch Insulin Pump
Israeli company developing new reusable square insulin pump that has Bluetooth for smartphone communication.
The description is a bit cryptic, but it appears to be a two-part wireless system where the controller unit is sort of Walkman-sized. Granted, in this day of micro-devices that's not too exciting, but maybe that's the current trade-off for less invasive. I love the data I was get from the Guardian. But I don't love that long cannula and the mobility of the sensor that often makes your skin sore.
So I'm thinking, maybe we've all been too ambitious expecting a jump straight from needles & cannulas to the non-invasive dream. Maybe there's a step in between -- something semi-invasive that will help us with the comfort imperative. Then again, the data on that last link is at least two years old. And then I found this neat overview which is, oh... just about 10 YEARS OLD.
