Minimed 530G with Enlite


enliteIt’s a bird. It’s a plane. It’s the Minimed 530G with Enlite. It’s the fanciest, most advanced glucose regulated insulin pump available today. Thanks to FDA clearance, all of us who wear an insulin pump and a continuous glucose monitor are a step closer to the artificial pancreas.

Until the day when the software exists to detect the accurate insulin dose for glucose rising, we can thank Medtronic for catching us on the down-side. The imminent danger of a low is a lot more disastrous than the eventual damages a high can inflict.

The Minimed 530G with Enlite is the first insulin pump that allows users to set an automatic alarm that sounds if blood sugar becomes too low. The threshold suspend is set by you and your doctor. The pump sounds an alarm when you hit the preset threshold. If you do not act within 5 minutes, the insulin pump automatically suspends delivery of insulin for 2 hours.

To further the genius of the safest insulin pump available in the US, Bayer’s CONTOUR® NEXT LINK allows seamless integration as part of the MiniMed 530G Insulin Pump system, transmitting proven accurate blood glucose results wirelessly to the insulin pump.

For people who’ve been familiar with the previous generation Minimed CGM, the Enlite is getting rave reviews. It’s smaller, more comfortable, and more accurate than former versions. And the Minimed 530G works hand-in-hand with the Enlite CGM through wireless transmission of glucose readings from the bG meter mentioned above, Bayer’s CONTOUR® NEXT LINK.

If you’re like me and you wear and insulin pump and have a CGM, the pump is always on you but you may have lost the CGM receive once or twice. To err is human but to err as a human with diabetes can be unforgiving.The combination of the Minimed 530G with Enlite gives the wearer more accuracy, more consolidated gadgets, and more control of your diabetes in-hand and in real-time.

Would you buy a car without airbags? If the answer is no then you should consider the Minimed 530G with Enlite. It has the most important safety feature you must have in an insulin pump. Checkout the  Minimed 530G with Enlite today.

    I recently purchased a Revel/CGM combo system back in April, and apparently I was approved for a free upgrade to the new 530g system with the Enlite sensor, which is great! They sent me the pump and sensors and I had my training one week ago. I have 30 days from my training to figure out if I want to keep the new system or go back to the Revel with the Sof-Sensor. I’m here to tell you I’m going back. Here’s why.

    First, I’ll start with the benefits. (1) The new Enlite sensors are MUCH easier to insert and much smaller. And, they “last” in the pump’s mind for 6 days. (2) Also, the pump has the threshold suspend, which shuts off your insulin delivery when your sensor glucose drops below 60 – 90 (depends on the user setting), but that’s a mixed bag in itself.

    The bad: (1) The sensors are over twice as much as the old ones! Holy crap! Now, like every experienced Sof-Sensor user, I restarted existing sensors and got about 6 days (sometimes more, sometimes less) out of them. And usually I’d go one day without a sensor, so I’m at about 1 week/sensor. Looking at the medtronic website, for a 10 pack of the sof-sensors, it’s $439 (which seems to keep going up) — $43.90/sensor. The Enlite sensors are at $479 — $95.80/sensor. Granted, you get a small insurance discount, and then I pay 20% of the cost after the discount, but still, that’s some cash — they want almost $100 per sensor!!! So I thought, “okay, well, maybe it won’t be so bad if they last twice as long, the cost difference is minimal at that point”. Well, I just had to replace my Enlite sensor because it crapped out after 5.5 days — didn’t even make it to the advertised 6 days!! I’ll try a few more in my full 30 day trial, but I’m not expecting much better results.
    (2) Medtronic advertises this new sensor to be more accurate than the old one. I haven’t found that to be the case — it’s about the same. And as any experienced user knows, it sometimes takes a few kicks — I mean calibrations — for the sensor to finally get to the blood glucose you’re seeing. Mind you, I’m only a week in, but I’ll see how the rest of the trial goes. This causes a problem when you get to Threshold suspend…. (3). With a sensor that isn’t any more accurate (so far), the pump will think you’re below the threshold and start alarming like crazy. There’s no silent vibrate option for this, either — it just starts alarming, which is REALLY bad at work and everyone looks at you in a meeting. While I appreciate its concern for my health, most of the time it’s false alarms because the sensor isn’t accurate. For example, it’s saying my glucose is 59, when in reality it’s 85. And then the threshold suspend will keep alarming every 15 minutes (again, no vibrate option). I’ve just turned off the threshold suspend (you can at least do that). (4) If you look at European pictures of the Enlite sensor, you will notice the transmitter looks MUCH smaller than the one you get with Sof-Sensors/Revel. Well, the American version of this roll-out sticks with the old transmitter, so that’s not any smaller, either.

    So, they want me to pay twice as much for sensors that don’t last any longer, aren’t any more accurate, use the same old clunky transmitter, and come with a pump that makes you want to throw it through a wall every time it pulls a false threshold alarm. But hey, they’re slightly more comfortable! Thanks, but I’ll stick with the Revel and Sof-Sensor.

    If Medtronic can’t get this value-proposition fixed for me, I’m going to start looking at other companies for my next pump. I was originally with Animas for my first pump, but switched when their new pumps didn’t have 300 unit cartridges anymore. I believe Animas and Dexcom have a pretty good partnership, but don’t have an integrated pump/sensor system yet. If they can come out with that integrated solution and have a 300 unit pump available, that’s something to seriously consider for me. Until then, I’m going to be sure to advertise that this new 530g is a rip-off until they either get the pricing under control or make these sensors last longer.

    DO NOT GET THE SENSORS!!!!!!!!!! They do NOT work. They are horribly inaccurate!!!!!! Mine has been a total nightmare. My pump constantly shuts off saying that my blood sugar is low. I hate them!!! Minimed has not offered a single solution that has made any difference. The sensors will often be 100 points below what my blood sugar is. I have corrected for low blood sugar that I did NOT have because of this. It is horrible!!! The sensors just do NOT work at all. DO NOT WASTE YOUR MONEY. These sensors are going to kill somebody!!!!!!!!!!!!!

      I understand exactly your frustrations. Prior to starting this new system, I have the Medtronic pump and Dexcom Sensor. I like them both. At times the sensor is off but most of the time it is pretty accurate. Still, check blood sugar because capillary blood is more accurate than interstitial, Anyways, I feel uneasy that if the sensor is inaccurate, especially during sleep, it shuts off basal rate for 2 HOURS, your blood sugar can sky rocket. Not sure about all of this. I will give it a try see what happens. Any suggestions?

    I just got the new 530G pump with Enlite CGM system. I have previously used a Minimed pump with Dexcom CGM and loved it for the most part. Making the sensor send blood sugar readings directly to my pump was very appealing to me, but the system is so unreliable that whatever benefits the Enlite might have disappear. The pump loses the sensor at least 7-8 times a day for no reason. Even when I wear the pump on the belt clip on the same side of my body as the sensor, it can’t find the signal. When I called Minimed to try to solve this problem, they told me that you cannot keep the pump in your pocket or under your clothing because any friction at all disrupts the signal. They also told me that you cannot use the pump around cell phones or wireless internet. It makes you recalibrate when the sensor is lost also, which entails testing your blood sugar twice in a row. That means that I would have to test at least 14 times a day just to wear this dumb CGM. So basically this pump only works if you are naked in the wilderness without a cell phone and want to test your blood sugar at least 14-16 times a day.
