In development. The device is inserted into a vein under the collar bone. Suppose to last 3 years. No info if has Bluetooth connectivity, which I doubt because I think it’s too small to have a battery that last that long.

Thanks @CarlosLuis.
This is something I could totally get behind.

The linked article says the sensor is in the vein, but the electronics are in a box glued to the skin. No issue with battery size there.

My bad, I missed that even though I saw the picture of the lead and box. That’s troublesome to me. I have a chem/medi port that has a cannula into my vena cava vein.The port is completely covered with skin. When I am receiving an infusion the nurse wears a mask and carefully disinfects the area around the port. Then they insert the special needle and tubing for the infusion.
Now this thing has a lead going into a vein for 3 years that exits the body to a communications box.

Eliminating the interstitial measurement lag like this does sound like an improvement if they can avoid making blood clots, but what I really want is a safe IV insulin pump so we can have fast, short-lived insulin. The 5-10 minute lag in CGM is nothing compared to the half-hour lag in onset of sub-Q insulin, and the continuing action of that insulin over 5 hours and longer.

Where do you see electronics on the skin? Their website claims “no wearable component”.
I found a pic of where/how it’s implanted here- Glucotrack starts study enrollment of implantable CGBM – The World of Implantable Devices
This page also claims “no external components worn on the skin”- https://www.fiercebiotech.com/medtech/glucotracks-3-year-diabetes-sensor-implant-clears-initial-human-safety-trial

You are right about what they hope to make in the future.
I see “electronics on the” skin in the article linked from the first post. Paragraph 4, sentence 2 says
The CBGM sensor lead was placed intravascularly via a percutaneous procedure and connected to a prototype sensor electronics component that was placed on the skin.
The first article you linked shows a picture for a fully-implanted device. I can guess that the transmitter/battery part of that device would be charged as a phone is with a wireless phone charger, but that’s just a guess. I hope they can build it and it works, but that future system is not the actual prototype that was tested in the clinical trial described in the first article. I’m somewhat oversensitive to the difference between devices that actually exist and devices that are still being worked on.

I live in AlexandriaVA & was admitted to Johns Hopkins Medical Center for an Islet Cell Transplant. After 6 months and ketones twice from the anti-rejection meds I stopped continuing with it. Dr Tom Donner JH Endocrinologist is brilliant & warned me early my good blood pressure would permanently rise if I continued taking the meds & it happened t take blood pressure meds daily. Glucotrak looks very promising. But the current one is www. EversenseCGM Implant lasts 6 months & you can get it now. Look them up.

I like the thought of a CGM that lasts 2-3 years (from what I read). I figure there has to be a “exterior” component of some sort to transmit a BT signal, so that aspect isn’t a deal breaker. The issues for all of us would be how proprietary it is, what pump system(s) its compatible with, and who they partner with. Seems most pump manufacturers want a monopoly vice interchangeability; they sell more product and tie T1s to their system. More to follow…
