Do you use and like the Medtronic's MiniMed™ 780G?

I assume you understand how the Libre sensor works, in that it measures interstitial fluid and not blood, so there will be a difference in the readings. These readings will not change with the addition of the pump. I have decided not to go with a pump, but that is my personal decision; however, it might be perfect for you. I suggest you read as much as you can about how it works and what you need to do to use it. I know a few people who are more than happy with a pump, so I wish you good luck with your decision.

Hello, I use a Medtronic 780 with G4 cgm. It’s changed my life for the better. It had its issues, but it’s the best thing I have done for the treatment of my type 1 diabetes in my life. I’ll be happy to share the pros and cons.

The Libre is a cgm, so only measures your blood sugar levels. The Medtronic 780G is a complete system. It is an insulin pump with a built in cgm. The cgm tells the pump your numbers and the pump calculates how much insulin you need. So, it gives you constant levels of insulin delivery plus, micro boluses for corrections. And, backs off on delivery if insulin levels start trending too low. So, it’s an automated, fully integrated system.

The negatives are that the cgm can go wonky for no reason. That’s frustrating. Mine is usually very reliable though. Also, using this system is a lot of work. And, it’s expensive, unless you have good insurance coverage.

If you like using the cgm alone, you might also check out other brands of cgms that are not integrated with a pump. I used to use Dexcom. I found that the location of the placement of the sensor majorly affected my accuracy.

I don’t get concerned about the discrepancy in my cgm number from my blood meter unless it’s more than 30 points different. It’ll usually come around.

I am not a Medtronic user but I have read a lot about their closed loop 580G system. The pump and algorithm is very good. The weak area, as celia16 mentioned, is their CGM. Medtronic has struggled for years perfecting their CGM's. I have heard that Medtronic has made a partnership with Libre to produce a proprietary Libre CGM that will interface with their pumps. That would make for a major improvement in their closed loop system. I have also heard Medtronic is coming out with a 7 day infusion set to go along with a new 7 day CGM. Other CGM's now last anywhere from 10-15 days being the norm.
Do your research. I know some doctors/endocrinologist will push a single pump provider. They see you every few months but you have to live with that system 24/7, A lot of other pump manufacturers out there. And 4 year commitments to use that particular pump is common. I am on a closed loop pump system and it is the best thing for my diabetes control. Good luck!

I use the Medtronic extended wear reservoirs and infusion sets that last 7 days! Love that!

Medtronic 780 has a brand new cgm called Simplera. I think it’s only available to new purchasers. Short supply. It’s been available in Europe for a while. It’s gotten mixed reviews, but some say it’s awesome. I will try it when it becomes available for existing users.
