Tandem’s t:slim X2 Insulin Pump Now Shipping

Making future software updates possible from home and adding a new Bluetooth radio​

By Lynn Kennedy and Adam Brown

Tandem recently announced that its t:slim X2 insulin pump is now shipping.

The next-gen insulin pump is similar to the current touchscreen t:slim, but adds two new, key features for future innovation:

  • The t:slim X2 is compatible with the online Tandem Device Updater that recently received FDA clearance. This means users will be able to update the pump’s software from home in the future, making major device improvements possible within the four-year warranty cycle and without needing to obtain a brand new pump. Tandem hopes to launch an update in mid-2017 that will allow the X2 pump to pair with Dexcom’s G5 CGM.

  • The t:slim X2 also adds a new two-way Bluetooth radio to allow communication with more than one external device (e.g., a Dexcom CGM transmitter, a smartphone app, etc.).

An upgrade program will enable current t:slim and t:slim G4 users to transition to the next-gen t:slim X2 Pump for $0, $399, or $799, depending on purchase date (see more here). Future algorithms – once they receive approval and become available to users – may also carry additional cost

Tandem’s remote software update capability makes it the only pump company able to upgrade users’ devices without needing to ship an entirely new piece of hardware. Hopefully other companies will add this functionality too, since it allows pumpers to get upgrades far more quickly and without the significant costs of a brand new device.

In the future, automated insulin delivery algorithms could also be downloadable to the t:slim X2, once they are approved. Tandem expects its predictive low glucose suspend algorithm to launch by the end of 2017, followed by a treat-to-target hybrid closed loop algorithm in 2018.

It’s certainly an exciting time in insulin pumps, as the Tandem t:slim X2 follows the recently approved Medtronic MiniMed 670G hybrid closed loop system (launching in Spring 2017).
