Summary
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.
The twiist AID system was cleared by the FDA for use with CGMs that have received FDA designation as integrated continuous glucose monitors (iCGMs). As the twiist AID system gets closer to commercial availability, Sequel Med Tech will publicize the list of compatible CGM
*Recently FDA approved for people with type 1 diabetes ages 6 and up.

Patient Considerations
Active Lifestyle
Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof.
Waterproof. The pump, when connected to the cassette, has a rating of IP28, indicating protection from continuous immersion in water. The pump can tolerate immersion to depths of up to 12 feet (3.7 m) for 1 hour.
Avoiding Highs and Lows
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.
Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.
Comfort
Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors.
Low-profile. Low profile with an adhesive design that prevents the pump from catching on other objects.
Easy Insulin Dosing
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
Customizable. Can bolus from phone, smartwatch, or directly from the device without needing to be attached to your phone. The device also directly measures the volume (amount) and flow (speed) of insulin delivered with every micro-dose
Easy to Use
Simple design. Replaces regular insulin pen. No additional devices to add on.
Watch compatible. The twiist AID system is the first FDA-approved AID system that can be directly controlled from an Apple Watch.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
Discreet. The pump is in two pieces - the top (algorithm and battery) and the bottom (insulin chamber and AVS technology)
