New 'Smart' implant adjusts itself to fight chronic pain
NCT ID NCT06246526
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new type of spinal cord stimulator that automatically adjusts its signal based on how your nerves respond. It aims to improve pain relief and quality of life for 25 adults with long-term, hard-to-treat pain in the trunk or limbs. The device is already approved, and this research looks at how well it works in everyday use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Evoke closed-loop spinal cord stimulator (device)
- What this could lead to
- If successful, this could show that closed-loop spinal cord stimulation provides better, more consistent pain relief for people with chronic pain.
- What could go wrong
- This is a small, observational study with no control group, so results may not apply to everyone. The device requires surgery and carries risks like infection or lead movement.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Be 18 years of age or older at the time of enrollment. Diagnosed with chronic, intractable pain of the trunk and/or limbs, which has been refractory to conservative therapy for a minimum of 6 months. Subject has a minimum Visual Analog Scale (VAS) score of 60 mm or higher (where 100 mm indicates the worst imaginable pain) at baseline. Be an appropriate candidate for the surgical procedures required in this study based on the clinical judgment of the implanting physician. Be willing and capable of giving informed consent. Be willing and able to comply with study-related requirements, procedures, and visits. Exclusion Criteria: Subject is pregnant or nursing. Have a medical condition or pain in other area(s), not intended to be treated with SCS, that could interfere with study procedures, as determined by the Investigator. Have evidence of an active disruptive psychological or psychiatric disorder or other known condition significant enough to impact perception of pain, compliance of intervention, and/or ability to evaluate treatment outcomes. Have an existing drug pump and/or SCS system or another active implantable device such as a pacemaker, deep brain stimulator (DBS), or sacral nerve stimulator (SNS). Have prior experience with SCS. Be concomitantly participating in another clinical study.
