You should find out when the 670G will be available in South America. I believe it's rolling out now here in the U.S. during the spring of 2017.

The 670G is the first insulin pump that will adjust your basal rate based on your real-time blood glucose readings via the CGM.

In theory, you don't have to bolus. I am sure they don't recommend that, but, say you ate and forgot to bolus, your CGM would detect that your blood glucose is rising and the pump will adjust your basal rate to compensate for that rising blood glocose. It also predicts lows and will adjust your basal rate for that as well, not just "suspend" like the current model(s) do.

It's basically replicating your pancreas, which is pretty cool.

Don't quote me on this, but I think the 640G is no different than the older 530G. From what I can remember, the main differences between the two models is that the 640G is the new "body", which is the same as the 670G aesthetically, and it's also waterproof. Medtronic wanted me to upgrade a while ago but it wasn't worth it based on those two new features. So with the 640G, you get the new waterproof body and the new look of the GUI. I didn't care so much about the GUI because I used the Medtronic application on my iPhone with the little Bluetooth module they sell, which is the "Uploader". It sends the data from your pump to your mobile device via Bluetooth.

I want to get off the pump because I'm just tired of it being attached to me. It used to be more of an annoyance with the CGM. For example, the CGM has to remain nearby to the pump or it will disconnect and you have to go through the 2-hour warm-up process again. So, if I were to hop in the pool and take my pump off, I would have to try and leave the pump nearby so that it remained connected to the sensor. I would have to leave it on a chair and cover it with a towel. Then, one of my kids would take the towel off my pump and it would end up sitting in the sun. Once that happens, I'd have to replace the insulin reservoir. Also, being in the water for an excessive amount of time, the tape around the sensor would eventually fall off, which means I'd have to replace the sensor. Medtronic is good about replacing them, but, it requires a near 1-hour phone conversation with Medtronic support as they literally ask you a million questions before agreeing to replace the sensor.

Now, without the CGM and only the pump, it's not so bad. If I know I'm going out to do yard work or activities, I can simply suspend the pump or set a temporary basal, leave the pump in the house and go outside. While I still use the pump, I stopped using the CGM months ago. My numbers have been so stable for the past few months, the CGM was not necessary anymore.

I think it's also mental too. The pump makes the disease feel so permanent. When I was taking a shot or two daily, I wouldn't think about the disease for the remainder of the day. That's probably not such a great idea either though, I guess that's how one becomes complacent.

I hope things work out for you. I know that Medtronic has very affordable zero interest payment plans on the pump if your insurance doesn't cover it. I would assume they offer that outside of the U.S. as well; assuming you needed it.

I don't know about the 530, but the 640 does have this feature that suspends the insulin automatically if it detects that you go low. I thought that was super cool, specially for workouts.

The 670 will be available here in aprox 3 years. That's what they said at least.

Here in Argentina, the health insurance has to cover 100% of the costs of the pump. I'm probably gonna have to fight a little bit at first though since they're probably gonna try to avoid it.

Is good to know about the GCM. I didn't know it could be such a pain in the ass if you take it out.

That same fear of the 24/7 pump being attached to you was what was keeping me away from it. But at this point. With two 8.7 A1C in a row, and having tried with degludec, there´s no other option for me. I´m gonna at least give it a try.

I have a Dexcom CGM and a Tandem pump, so they don't talk to each other (yet). I haven't had any problems taking off my pump while swimming, or trying to stay in-range. I just leave the pump and receiver in the locker room, other than a bit of a gap in data, it doesn't cause me to have to repeat the 2 hour warmup or anything.

I use a SPI Belt to hold my pump which really helps me ignore it. I wear the belt under my clothes and never take it off. It's nice because the pump isn't loose in my pocket, the tubing never gets in the way, I don't have to take it out of my pocket when I go to the bathroom, and its safe all night even sleeping commando.

So if you do get a pump, I recommend looking into the belts, even if you don't wear it all day, it's quite handy for when you are playing sports.

Can't comment on the feeling "tethered" to the pump. Guess everyone reacts different to things. Personally I feel more like a normal person with the pump than I ever have since being diagnosed 6 years ago. I am playing sports again, can travel for my job doing long hours with irregular access to my supplies or food, handle my boluses at a restaurant without anyone seeing, and don't really have to think about my diabetes much, other than typing in the carb count for my meals, the pump and CGM do almost everything else.

Thanks! I didn't know those existed. I'm definetly gonna ask my wife to bring me one. She's going to the states in a couple of months.

I'm also gonna ask about what happens when you disconect from the pump.

I'm on my way to getting it now. I have to go through the burocracy and the health insurance trying not to cover it.

I've never had a medtronic but I think all tubed pumps are about the same. When I want to disconnect for a shower, swimming or whatever, I can simply disconnect the tubing from the infusion site (it has a little plug) and let my basal insulin drip about for a bit (it's a tiny amount, can't really tell). If it's just for a bit, like a 15 minute shower, I often do that and ignore the amount missed.

When I'm disconnecting for longer, I will stop insulin delivery. On my tandem, it will beep after 15 minutes to remind me (gee thanks...). If it's going to be a while, you can give yourself a small amount of insulin before disconnecting to replace the missed basal.

Then when I am done, I plug the tubing back in, and resume my insulin.

Just curious Gonzo, if your activity level is lower some days, whether it is working on techniques or your opponents require lesser intensity on your part, do you have time to a more strenuous activity afterwards on those days?

I do. That's a good idea! I could jump rope for a little bit after the class if I feel like it wasn't enough.
