Real-life user testimonials

The thing that I love most about twiist is how it reduces the mental load of living with diabetes for me. It is such a relief to be able to live life and not feel captive to my diabetes.

- Cheyne

My favorite thing about twiist is not having to take shots anymore.

- Macy (Age 6)

There are so many things I love about this pump. I have tried a lot of things but one of my favorite things being a mom to a child with type 1 is the glucose prediction feature because I look at her prediction before we go to bed at night and I can see if she is expected to be steady while she sleeps, which gives me some confidence that I can have a good night's sleep.

- Falyn

INDICATIONS FOR USE
The twiist system is intended for the subcutaneous delivery of insulin, at set and variable rates, for the management of diabetes mellitus in persons requiring insulin, ages six and above. The pump is able to reliably and securely communicate with compatible, digitally connected devices, including automated insulin dosing software, to receive, execute, and confirm commands from these devices. The twiist system is intended for single patient, home use and requires a prescription.

The twiist Loop algorithm is intended for use with compatible integrated continuous glucose monitors (iCGM) and the twiist alternate controller enabled (ACE) insulin infusion pump to automatically increase, decrease, and suspend delivery of basal insulin based on iCGM readings and predicted glucose values. It can also recommend, and with the user’s confirmation, control the delivery of correction boluses when glucose values are predicted to exceed user configurable thresholds. The twiist Loop algorithm is intended for the management of type 1 diabetes mellitus in persons six years of age and greater. The twiist Loop algorithm is intended for single-patient use and requires a prescription.

The twiist Automated Insulin Delivery System includes a simple bolus calculator available when Loop is off. It is indicated for use for aiding the user in determining the bolus insulin dosage for management of diabetes mellitus based on consumed carbohydrates, operator entered blood glucose, insulin sensitivity, insulin to carbohydrate ratio, target glucose values, and current insulin on board.
CONTRAINDICATIONS

The twiist AID System is not intended for anyone unable or unwilling to:

  • Test blood glucose (BG) levels as recommended by their healthcare provider
  • Maintain sufficient diabetes self-care skills.
  • See their healthcare provider regularly
  • Demonstrate adequate carbohydrate-counting skills (preferred, not required).

The user must not:

  • Have difficulty seeing
  • Have difficulty hearing
  • Have deficient cognitive capabilities
  • Have physical impairments that would make operating the pump or iPhone difficult
