Neither company has said anything which truly supports the hope of Dexcom sensors working on Medtronic pumps. My personal opinion is that this is very unlikely to happen.
I certainly would not expect it to be considered unless Medtronic’s next generation of CGM sensors completely flops after it is introduced. So we’ll just have to wait and see how that goes. But definitely the wait would be longer than “within a year”.
Medtronic has been working on their version of integrated CGM for decades. I don’t see them throwing in the towel and being dependent on Dexcom without trying a bit longer. What I think is more likely is that Medtronic would attempt to take over Dexcom. Remember, Medtronic started it’s line of pump technology by buying MiniMed.
The fact that at this time none of Dexcom’s management would support an acquisition is the biggest barrier to that. Well, that and the fact that Dexcom’s current stock price would make a hostile takeover very expensive!
