A sensor that lasts a year: Eversense 365 heads to Europe
Senseonics submitted its one-year implantable Eversense 365 CGM for European (CE mark) approval in February 2025.
There is a glucose sensor designed to last up to a year, and in early 2025 it took a step towards approval in Europe. It is called Eversense 365. Unlike the stick-on sensors most people change every one to two weeks, this one is a small sensor that a clinician places just under the skin, so there is nothing to swap out for months. It is not confirmed for the UK, so this is one to watch rather than something you can ask for today.
- It is a CGM (continuous glucose monitor, the sensor that reads your glucose through the day) built to last up to a year.
- The maker, Senseonics, has submitted it for a CE mark (the European approval that lets a device be sold), which is the start of the process, not the finish.
- The first European countries lined up for it did not include the UK, and there is no confirmed UK availability yet.
- It is mainly worth knowing about if frequent sensor changes are a real pain point for you.
What Eversense 365 is
Most sensors people wear are stuck to the skin and last one to two weeks before you replace them yourself. Eversense works differently. The sensor is placed just under the skin in a short appointment with a clinician, and it stays there. The 365 version is designed to last up to a year, which the company describes as the longest-lasting continuous glucose monitor available.
In February 2025 Senseonics completed its submission for a CE mark, the approval a device needs before it can be sold across Europe. Submitting is not the same as being approved, and being approved is not the same as arriving on the NHS, so there are still real steps ahead.
When UK readers might realistically see it
Here is the honest position. The countries first lined up for launch in Europe did not include the UK, and there is no confirmed UK date or route yet. A device being sold privately in some European countries does not mean it is on the NHS here, and NHS availability is the bar that matters for most people.
None of this changes what you use now. Your current sensor keeps doing its job, and a year-long implant is not a decision anyone needs to make today. If it does reach the UK, your diabetes team is the place to ask whether it would suit you, because an implanted sensor is a different kind of choice from a stick-on one.
