Trying the Eversense implanted CGM

The removal of my first sensor went quick and easy on July 1. The Dr. noted that he has had enough practice to refine his removal procedure. He grabbed the sensor with tiny forceps and used a scalpel to cut through some adhesions around the sensor and out it popped! The scar from the removal looks a little bigger than the insertion scar but it healed over quickly and does not bother me. By getting Sensor #2 inserted on June 20 I was able to wait until June 29 to start the 24-hour warm up, followed by initialization (4 calibrations) on June 30. I was getting good data on June 30 because the insertion site had “presoaked” for 10 +/- days.

The Eversense has been most useful to me when I’m outdoors or playing hockey. My summer project has been heavy landscaping (building a gabion wall using a wheel barrow to move 30 tons of rocks) which risks breaking both my phone and watch. I put my phone away, take off the watch and use the vibratory alerts on my arm. I also like the fact that I can run out the door without worrying about grabbing my phone every time.

Nice, glad to hear everything went smoothly. My Dr. Is on her 7th eversense, so hopefully, it should be fine. I don’t think I was as affected the first 9 days or so, but my Dr said others were, and I think I’m in the the minority… I’ve also played with cgms since the Dexcom G4, so i was expecting a little learning curve… I’m still using xdrip though…the watch face and predicted MP3 sounds for low predictions, low, or high glucose warnings make it easier for me…60 days so far…

I’ve been getting bad BG data from Sensor #2 lately and am starting to wonder if I’ve got a bad sensor, or if I somehow disturbed it causing it to lose accuracy? At my endo’s suggestion I went ahead and started a Dexcom G5 for comparison, and to get back in the swing of receiving alerts for lows. Here is a comparison of what I am seeing (Eversense plot on the top, Dexcom G5 below):

There are multiple inaccuracies on that plot of July 12 data. It almost seems like the sensor is stuck in a range and will not register higher or lower than that range. I’ve sent a load of data to technical support who is escalating it and will (hopefully) determine what the issue is.

Back when I started with Sensor #1, I used a Dexcom G5 for comparison and found good agreement with Eversense. Here is a typical plot from a similar day using Sensor #1, which seemed to track well with the Dexcom:

Eversense technical support did well with reviewing my inaccuracies on Sensor #2… they reviewed my data and determined that the sensor malfunctioned starting on July 8. (That coincides with a fairly intense hockey game when I first noticed some false alarms for low BG when I knew I was not low). There’s no way to determine if I dislodged it or concussed it’s little brain or ?? but it all makes sense.

The resolution is a new sensor was offered without any prompting. I might decide to wear one water wing to protect this next sensor…although I had no problems with rough treatment of sensor #1.

Did you switch arms? If yes, was 2nd placement in your dominant side? Do you notice more physical activity on that side?

That’s a possibility…the bad sensor is in my dominant right arm. The current theory of mine is that I dislodged it somehow, possibly a hit or fall (which did not register with me at the time). It feels like it’s closer to the surface than it should be. There was redness and it was sore during that week which healed in about a week with no improvement in accuracy. I have some travel planned and won’t be able to have it replaced until mid August.

So just a quick update on my 2nd sensor…they also switched it to the right arm, and I had 3 eversense reps there, with a lot more micromanagement, even though it was my provider’s 17th procedure… but my 1st sensor was probably similar to your 2nd, In That it may not have been deep enough, and the rep kept saying she had to cut more and deeper… 3 times before it was successfully removed… I also read all sensors will work for 6 months, but they force it to stop with software… very annoyed, but my 2nd sensor is working well, even though both arms are still healing…might take 2 weeks because its already been 1 week… I ended up buying steri strips and tegaderm because the removal side was still bleeding… I was able to go camping and took if off when I was in the lake definitely longer than 30 minutes…I did have to replace the transmitter, as it wouldn’t remain charged for more than 40 minutes, but eversense next day mailed the new o e, and its

Thanks for the update! Unfortunately it seems like you and I are the only Eversense users on the interweb these days. I switched back to Dexcom G5 in July when the second Ev sensor was off line and am waiting until late September to implant the replacement sensor.

Wondering if Senseonics will still be around in 2020. Their stock is headed towards penny stock territory and I think the only way they survive is if they are bought out. My insurance company has not made any moves toward covering Eversense. I have been stockpiling G5 sensors this summer to take me through early 2020 after I am done with the second Eversense sensor. Can’t seem to stockpile G5 transmitters though.

Yeah. That sums it up.

It is going to cause a cascade of stock/business issues if the SENS stock pricing falls below $1 and stays down there. Mannkind flirts with similar bad business scenarios. Hard to talk about it much here as these forums are not business focused and there are too many emotions tied into the usage of the products.

The Senseonics Eversense technology would (IMHO) make a nice complement to the Dexcom offerings. Wouldn’t it be cool to be able to choose if you want the Dexcom external (more or less) sensor or the Dexcom implant sensor?

More than two G5 (or G6) transmitters on the shelf and you likely would run into issues with the battery discharging before you got full use out of the one that sat the longest on the shelf.

For sure. Another pipe dream is a vibratory alert on my arm from a Dexcom rechargeable transmitter…if the two companies could get into some sort of merge/licensing or other type arrangement. Seems like the CGM tech is going through such rapid improvement that almost anything is possible a few years out. How about a universal sensor that can work with a wide variety of proprietary transmitters? Then the rest of the tech industry can improve/sell transmitters. That would be cool.

Keep all of your old transmitters…you can look up ways to swap out the battery with a dremal, and then epoxy it back up…I only had 1 when I tried and failed, but I think I would have succeeded if I had another one…they are already using xdrip with the libre 2 in Europe, so hopefully that’ll be here soon…my insurance won’t cover Dexcom…

I also looked up why the stock dropped, looks like they offered 28 million to the public which dropped the price an equal amount to the money generated…definitely betting on the future, which I’m OK with…I just hope they fix their app soon…I use it to calibrate and that’s it…xdrip rules…different MP3 ringtones for low, predicted low, high, also a screensaver when the phone is charging and watchfaces…I told the 3 reps who were at the Dr office, but they weren’t sure how fast the suggestions would be implemented…its also impossible to show them how it works because of the 24 hour delay for the readings…one rep was a type 1, and the other had 2 type 1 children, so they were very interested.

Here is a doc that talks in depth of the insertion process.

I skip over all the big words and focus on the little words.
But still found it very interesting.

And the pictures are great also.

For me, the section on “Insertion and Removal of the Eversense Sensor” which starts at the bottom of page 4 and runs to the top of page 8 was what I was really interested in reading about.

Huh… I wonder if that’s what some of my doctors in the past have done? :thinking:

Great timing, @Thomas! I’m in queue for implantation sometime soon and have not looked into it at all. I’ll look at this and scare my doctor by knowing something about it. :grin: Thanks for posting this. :hugs:

I’d love to see that, @John58. If you do ever get to it. Because of all the info you shared with me, I’m getting one put in and would really enjoy seeing someone else’s numbers in comparison.

Things I read in your update that did stand out are about the removal being trickier than the insertion. (Maybe I’m projecting “trickier”… if it’s just about the scar, I don’t care, but I am not interested in “tricky”). Oh, and the elbow buzzing… you’ve mentioned the sensation previously, but I don’t think I’ve ever heard mention of it being near the elbow. This might be worth my asking… somebody. I don’t know who I would ask, but elbow buzzing is something I already experience. :woman_facepalming: I wonder if that would be a problem?

You don’t actually have to answer that. Just over caffeinated.

Well I am now getting Sensor #2 inserted in late October. I was originally scheduled for late Sept, and we (endo and I) decided to delay a month. Long story, but it involves an infected cut I was knocking down with antibiotics and the endo recommended that I be positive the infection was gone before we insert the Eversense. I did get the haywire sensor removed on Sept 24. The removal was not as crisp and quick as #1 back in July (seems like ages ago, I am running around too much these days) and took about 10 minutes. The wound from sensor removal seems to be healing OK.

Maybe we can compare Eversense accuracy after I get the next sensor?

Let me guess… you will be wearing Eversense, dexcom G6, G5, Medtronic G3, and Libre all at the same time. We want a comprehensive review!!!

The removal scar was a little larger than the insertion…I don’t care about scars, but I know some people do, in which case, eversense may not make sense…unfortunately it sounded like john58 had one if the recalled sensors…its supposed to be fixed now…

That is about what I would expect from a subcutaneous implant. Lengthen that to about 3" and you have a pacemaker insertion scar. Hopefully they create a biodegradable unit, since the insertion scars would be so much smaller.
