Summary

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.

V-Go is a convenient credit card-size patch pump that adheres to the skin and can be worn for 24 hours. This system is designed to be used with fast-acting insulin for people with type 2 diabetes who require 20, 30, or 40 units of insulin per day. Users can administer two units of insulin with every press of a button on the device. This device is a hybrid between injections and an insulin pump to allow for discreet dosing without the need for programming or multiple injections. 

FDA-approved for people 21 years of age and older with type 2 diabetes.

Patient Considerations

Active Lifestyle

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.

Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly, but the device is water-resistant. 

Avoiding Highs and Lows

Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.

Limited customizability. System requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day. 

Comfort

Low-profile. Low profile with an adhesive design that prevents the pump from catching on other objects. 

Free of tubing. Patches do not have tubing, but it must be worn in areas that are easy to reach for insulin dosing. 

Easy Insulin Dosing

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

Simple with few steps. 24-hour bolus range: up to 36 units per 24 hours, doses in 2-unit increments. Preset basal rate of 20, 30, or 40 units per 24 hours.

Easy to Use

Watch compatible. The twiist AID system is the first FDA-approved AID system that can be directly controlled from an Apple Watch.

Simple with few steps. Patch is replaced every 24-hours with insulin administered at the click of a button. 

Fewer Fingersticks

Factory-calibrated sensor. Fingersticks needed for backup only.

Frequent finger-sticks are required.

Privacy

Discreet. The pump is in two pieces - the top (algorithm and battery) and the bottom (insulin chamber and AVS technology)

Hideable. Bulkier patch pump, but not as noticeable as injections. Bolus button can be used discreetly through clothing.
