Spinal fusion joins two vertebrae with an implant and bone graft, and in a share of patients the bone never fuses. The EU project Intelligent Implants won puts that failure rate at 18%. The company, registered in Mölndal, Sweden, in 2018, designed SmartFuse: a spinal cage with electronics inside that delivers electrical stimulation to encourage bone growth and senses how the fusion is progressing, powered and read wirelessly from outside the body.

The European Innovation Council granted €2.5 million towards a €3.88 million project. Its report describes a design freeze and plans a first-in-human study for mid-2024. We could not find that study in the main trial registry, CORDIS shows no final results, and the company's website did not respond when we checked in September 2026. Swedish filings show a company still operating, with nine employees and a SEK 14.7 million loss in 2024.

Where Intelligent Implants Stands Today

According to Swedish register data published by Allabolag, Intelligent Implants Sweden AB is active, with nine employees, revenue of SEK 2.9 million and a loss of SEK 14.7 million in 2024, and a healthy cash position at year end. Martin Larsson is chief executive and sits on the board. The company's stated purpose is the development and commercialisation of medical technology products.

Beyond the register, the public trail is cold. A search of ClinicalTrials.gov for SmartFuse returned no studies, and the company's website did not load. We found no public announcement of a first-in-human procedure, regulatory approval or funding round since the 2021 EIC award.

The Technology: An Implant That Reports Back

Electrical stimulation has long been used to help bones heal, usually with separate stimulators. SmartFuse builds it into the fusion cage itself. According to the CORDIS report, the electronics fit in "less than 1cc of volume" on flexible circuit boards, sealed in a welded titanium capsule, with thin-film platinum electrodes for both stimulation and sensing, in a PEEK and titanium cage designed for cost-effective manufacture. An external unit powers and reads it.

"FIH (first in human) clinical study in mid 2024."

What the EIC Project Promised, and What CORDIS Shows

SmartFuse ran from April 2022 to November 2024. The only report on CORDIS covers April 2022 to March 2023 and describes a "design freeze candidate system" for the implant, electronics, software and external unit, with design verification and validation planned for the rest of 2023 and a first-in-human study in mid-2024. No later results have been published on CORDIS.

What Has Happened Since the Award

The Money

In October 2021 the company announced €4.5 million of EIC Accelerator blended finance, grant and equity combined, to "accelerate the completion of the clinical pilot trial and the preparation of the pivotal study". CORDIS records €2.5 million of that as grant. The award was blended finance, but we found no record of the EIC Fund investment being made, and the company is not on the EIC Fund's portfolio pages we checked. We found no announced private funding round. The 2024 accounts show the company funding losses of about SEK 15 million a year.

What cannot be checked

Whether SmartFuse has been implanted in a person, what the verification tests showed, who funds the company and why its website is offline are not public.

Why Europe Should Care

Failed spinal fusions mean repeat surgery and long-term pain. An implant that helps bone fuse and tells surgeons how healing is going would be a genuine advance, and the EIC paid most of the cost of designing one. Whether that investment leads anywhere depends on clinical work that the public cannot yet see.

What the project promised

A new gold standard for spinal fusion surgery using wireless smart implant technology.

What the record shows

A design freeze, a planned 2024 human study that cannot be found, and a small, loss-making company with no working website.

The Verdict

Designed, then out of view

The EIC funded a promising idea through to a finished design. What happened next is invisible: no registered human study, no final report, no product news, and a website that no longer loads. The company still exists and still spends. The EU should be able to tell the public whether its €2.5 million reached a patient.
