New t:slim G4 is in the works!

"In addition to seeing continued, increased adoption of the t:slim Pump and meaningful gross margin improvement in the second quarter, we also made significant progress with our new products in development," said Kim Blickenstaff, President and Chief Executive Officer of Tandem Diabetes Care. "We recently submitted a PMA application to the FDA for the t:slim G4™ Insulin Pump, which integrates our t:slim technology with the Dexcom® G4® Platinum CGM System. This is an important milestone for Tandem as we work to expand our product portfolio to meet the various needs of the diabetes community."

how long does this process usually take to actually see the product in use?

after approval, about 1 hour <<>>.
Problem is getting approval might be a year or more.

Approval can take year(s)....if you are eligible for a new pump now, get the existing t: slim. I would confirm with the rep, but my understanding is the existing version has a bluetooth built in and may be able to be integrated with the G4 as well once FDA approval is made.
