What Is the Twiist?
The Twiist is a next-generation automated insulin delivery (AID) insulin pump developed by Sequel Medical Tech. It enters the market with a modern design philosophy: a smartphone-first control interface, an innovative reservoir filling mechanism designed to eliminate the air bubble problem common in traditional pumps, and a sophisticated closed-loop algorithm.
The diabetes technology landscape is evolving rapidly, and Twiist represents a newer generation of thinking about how AID systems should work โ built by engineers and clinicians who studied what patients and providers found frustrating about existing systems.
๐ Newer Technology: Because Twiist is a newer entrant to the US market, long-term real-world outcome data is still accumulating. Our endocrinologists stay current on the latest clinical evidence and can help you weigh the tradeoffs of an established vs. newer AID system.
Key Design Features
- Twist-to-Fill Reservoir: A novel reservoir design intended to simplify filling and reduce air bubbles โ a common frustration with traditional reservoir loading
- Smartphone App Control: Designed around a modern mobile app experience, allowing intuitive bolus delivery, history review, and algorithm adjustments from your phone
- Closed-Loop Algorithm: Integrates with compatible CGM sensors to deliver automated basal adjustments and corrections based on real-time glucose data
- Modern Hardware: Designed with current materials and manufacturing approaches, drawing on lessons learned from earlier-generation pump hardware
โ Potential Advantages
- Modern smartphone-first design philosophy

Frequently Asked Questions
The Twiist is a next-generation automated insulin delivery (AID) system developed by Sequel Medical Tech. It is a tubed insulin pump designed to work with CGM technology to form a fully closed-loop system. Twiist is notable for its twist-to-fill reservoir design, smartphone integration, and advanced algorithm. It has received FDA clearance and represents a newer entrant in the AID pump market.
Twiist differentiates itself through its unique reservoir filling system (no more air bubbles from traditional fill methods), a purpose-built smartphone app interface, and an algorithm designed to be highly responsive to glucose trends. It aims to simplify the pump experience with modern design choices while maintaining strong automated glucose management performance.
Twiist is designed to integrate with leading CGM systems. Check with your endocrinologist or the Sequel Medical Tech website for the most up-to-date compatible CGM list, as CGM integration partnerships continue to expand.
Twiist has received FDA clearance and is in the process of broader availability in the US market. Because it is a newer device, availability may be more limited than established systems like Omnipod 5 or Tandem t:slim X2. Our clinic stays current on availability and can advise you on timing and access.
Twiist may be appealing to patients who want a modern, smartphone-centric pump experience and are open to newer technology. It may be particularly interesting to patients who find current AID systems' reservoir-filling process cumbersome, or who want the latest algorithmic approaches to closed-loop control.
As a newer device, insurance coverage for Twiist is still being established. Coverage varies by plan and is expanding. Our endocrinology team can help assess your specific insurance situation and discuss options for accessing newer pump technology.
