Summary

The iLet Bionic Pancreas is the first and only commercially-available, automated insulin delivery system that determines 100% of insulin doses without carb counting - offering better results with less work.

The iLet only needs a user's weight to get started. It then learns and adapts to the user's insulin needs based on their meal announcements and CGM data (Dexcom CGM or FreeStyle Libre 3 Plus sensor).

The InPen system enhances management with multiple daily injections because it tracks data in real-time and offers personalized dosing recommendations. This system combines the Guardian Connect CGM with smart insulin pens for more time in range.

Device Details

Overview

This system requires very little input from the physician or user.  It only requires the user to input their weight to get started (glucose targets can be adjusted). Instead of carb counting,* the iLet just needs an estimate of the carbs in your meal – Usual for me, More or Less. The iLet is paired with either a Dexcom CGM or the FreeStyle Libre 3 Plus sensor. 

*User must be carb aware.

Discreet and modern option for people using multiple daily injections.

Patient Considerations

Active Lifestyle

No exercise mode. Pump will continue to increase or decrease insulin dosing in response to changing CGM glucose levels as usual. However, insulin can be stopped at user's discretion. Pump is water resistant for up to 12 feet for 30 minutes. 

Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof. 

Avoiding Highs and Lows

Auto basal and bolus insulin. 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.

Limited customizability. System integrates the Guardian Connect CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day. 

Comfort

Somewhat comfortable. Low maintenance sensor. Larger pump option.

Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors. 

Easy Insulin Dosing

Meal announcement controller. User must be carb aware. The iLet calculates and doses 100% of the insulin throughout the day and night, allowing the user to focus on other things in their lives. Please note: even when you use the "Meal Announcement." your blood glucose levels could rise above 250 mg/dL for a few hours. You'll need to be comfortable letting the iLet regulate your blood glucose.

Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin. 

Easy to Use

Easiest to Use. User weight is the only input required to start using the insulin pump. No carb counting *, correction factors, carb ratios, or pre-set basal rates required.

*User must be carb aware.

Simple design. Replaces regular insulin pen. No additional devices to add on. 

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

2 daily finger-sticks are needed to calibrate the sensor. 

Privacy

Discreet. Ability to check blood sugar on phone. Minimal pump interaction is required. Pump has tubing but can be clipped to clothing or placed in a pocket to be discreet when needed. 

Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
