Spine Surgeon Led
SynerFuse® e-Fusion™ (also known as e-TLIF™) is an investigational procedure that pairs spinal fusion with direct nerve stimulation to provide Ultra Low Energy™ (ULE™) Technology. It is designed to address chronic low back and leg pain in spinal fusion patients.
Too many people are living with outcomes that are not acceptable to them.
An unacceptable number of people rely on opioids after a successful spinal fusion.
These figures describe the disease state and are provided for context, not a product claim.
One procedure – Integrated technologies
During lumbar fusion surgery, the surgeon also places a lead designed to deliver direct nerve stimulation at the same spinal level, through the same incision. Fusion and Ultra Low Energy™ (ULE™) Technology happen in one operation instead of in separate surgeries.

Built around the patient and the surgeon
Patient-focused and integrated
Stimulation is placed during the fusion surgery the patient is already having. The procedure is designed to improve the patient experience by integrating Ultra Low Energy™ (ULE™) Technology with spinal fusion.
Surgeon-led
Neuropathic pain is designed to be addressed at the same spinal level as the surgery, through a single incision. The system is designed for spine surgeons.
ULE™ technology
Ultra Low Energy™ Technology is designed to work alongside the fusion hardware the surgeon already prefers.
Clinical research
SynerFuse® completed a 15-patient feasibility study of the e-Fusion™ procedure with the University of Minnesota, South Bend Orthopaedics and RQM+. A 150 patient clinical trial is being prepared with the Big Ten Neurosurgery Consortium, a network of 17 member institutions serving patients across the United States.
