Closed loop insulin pump experience?

+1 like
Hi there! Is anyone using or interested in the new closed loop systems currently on the market or on their way? What is your experience with them so far? I'm considering getting on Medtronics 630G and heading toward the 670G.

I just got my 670g about a month ago. I am one of the first 6 in SWFL and one of 12 in FL. I love love love it! I haven't been in this "tight" control ever!

I have been using it now for about a month and my A1C went from 7.9 to 6.7! Who would have thought!

The CGM is MUCH MUCH more accurate! It is usually 1 or 2 numbers off from when I finger stick, you can also wear it for 7 days now vs the 1st which was only 3

It is an amazing product! Go get one as quick as you can!

I'm on the 530G right now.  I love using MiniMed Connect to see my cgm info on my phone, and that is not an option with the 630G.  I decided the Connect was more important to me than the new features of the 630G, so I have not upgraded.

However!!!  I absolutely do plan to upgrade to the 670G in the spring.  I tend to have a lot of low blood sugars, and I'm very hopeful that the closed loop system can help me with that.  

I volunteer as a patient ambassador for Medtronic, so if you have specific questions about the new pump I would be happy to answer them for you.

I have been using the 630G system since October, previously like Karen, on the 530G.  
I absolutely love the 630G system.  The CGM works great for me, as it did with with 530G.  I can't wait for the 670G to come out in the spring.

I wrote a product review on the 630G system -- feel free to ask me anything.

I'm honestly really nervous about the whole thing. What if it malfunctions, reads my sugars wrong... yada... yada... yada... all the same fears I had before I went on my ombnipod (which I love!) but still those same fears keep popping back up!!

I have talked to a few different people including females that have been on the study for the Medtronic study for the closed loop system. The general consensus I'm finding from them is this 1)CGM had been inaccurate, 2)no one in the study has had an A1C less than 6.4 and due to the fact that it does not treat lows with a glucagon they are upset that it has been called an artificial pancreas as it is not that. I know Omnipod is looking at one and in early studies of there's and release is in 2018. Personally, the A1C which is in guidelines bothers me as my A1C is 5.6 and has been that or 5.8 for the last 2 years. CGM not being accurate is also an issue and my Dexcom G5 is very accurate as long as it's caliberated correctly. I especially like the fact that you can now dose from it. I have tight control which wouldn't be possible without me watching everything like I do which comes from years of trial and error. With the fact I have found the correct combo of insulin/carb/fitness that my doctor lets me tweak as I feel necessary. So until I see something similar to my way or Omnipod's closed loop shows promise as I do look at study results I will not go to a closed loop system. Plus I had a bad experience with getting insulin when I wasn't supposed to be and due to being hypo unaware my Dexcom has been an invaluable asset to my care. I added Omnipod to it in Sept 2016 after finding it brought a tighter more easier management I needed when working.

Thanks so much for the responses everyone! I have decided to go ahead with the 630G and intend to upgrade to the 670G when available. I'm hoping I don't regret it, my insurance will cover a new pump every 5 years so I need to live with it for that long. My big hesitation was the sensor. I tried Medtronic's first generation which was a terrible experience and I did not use a CGM for a long time. Then I had a great experience with Dexcom and wished to stay with it but I'm taking a risk for the ability to upgrade to the 670G with Medtronic. I have heard that their sensor has improved quite a bit and that it is much more accurate and has less alarming going on. We will see! Whatever the case, I still remember NPH and MDI so I'm better off!

Let me know if you have any questions about the 630G system - feel free to reach out directly if you'd like!

Hi.  Please keep us all updated on how your new minimed pump works.  I too tried the first generation sensor with them, and couldn't tolerate it.  I've loved my dexcom for years now, but am really excited by the closed loop system.  I'm sure many of us will be waiting to hear actual experiences with it, as far as accuracy and comfort.  The best of luck, I  certainly hope it lives up to all the hype !!

I just switched to the 630G, after years on an Animas pump with the Dexcom.  I will be upgrading in the spring to the 670G.  I loved Dexcom, but not my Animas. I  just started my first sensor tonight, so I can't address the accuracy yet.  I do like that I only have to have a pump in my pocket, instead of carrying both a pump and a receiver.  

Someone earlier posted about safety of getting too much insulin. It is my understanding that the 670G actually has two sensors on it, rather than just one. So the two have to be within a slim range of one another before the pump will give/stop insulin.
