After startup, the iLet learns about YOU – your basal insulin needs, how to correct you to target, and how much insulin you need for your meals. The goal of the iLet is to reduce the burden of diabetes management.
The iLet Bionic Pancreas is the only insulin delivery system that makes 100% of your dosing decisions – so you don’t have to.
-No carb counting*
Instead of carb counting everything on your plate, the iLet just needs an estimate of the carbs in your meal — Usual for me, More or Less.
-No corrections
The iLet makes the corrections for you. If you’re trending high, it will automatically give you more insulin to bring you back in range. If you’re trending low, it will reduce your current insulin dosage.
-Dosing decisions made for you
The “Bionic” part of the iLet that communicates with your CGM and makes all of the insulin dosing decisions—no carb counting, no correction factors, no adjustments.
-No pre-set basal rate
iLet learns your needs and automatically adjusts your basal rate on the go.
-Simple setup
No settings are required to be entered or adjusted—the iLet system only needs your weight to get started.
-Small but mighty
Small (1.9” x 3.6” x 0.6”), lightweight and easy to put in your pocket or clip to your clothing.
-Talks to your CGM
Your iLet device communicates directly with your Dexcom CGM or FreeStyle Libre 3 Plus sensor to know where your glucose is headed.
-Water resistant
If you drop your iLet in water—no problem! It’s protected in up to 12 feet of water for up to 30 minutes.
-iLet App
The iLet App displays data from your iLet home screen in real time so you can view your current glucose, trend, notifications, and other important information directly on your phone. It also supports data synchronization, reports and updates for your iLet and allows you to share your data with your healthcare provider.
-Create your Bionic Circle
With the Bionic Circle App, up to 10 friends and family can remotely monitor you to see CGM values, meal announcements, and insulin doses and to receive alerts (Urgent Low / Urgent / Low Soon / Low/High / No Data).
Please note that any changes made to your iLet therapy settings should be done under the guidance and supervision of a qualified healthcare professional. Before making any adjustments, it is important to consult with your doctor to ensure that the changes are appropriate for your individual needs and health status.
