SpF® Implantable Spine Fusion Stimulator

Your doctor may prescribe the SpF® Stimulator, an implantable electrical stimulation device that has been shown to increase the probability of fusion success (1, 2, 3, 4). Electrical stimulation adjunctive therapies have been used for more than 30 years to promote spinal fusion(4).

Backed by clinical studies, the SpF® Stimulator is a proven, safe and effective adjunctive treatment that increases the probability of the healing of your fusion. The original SpF® device received FDA approval in accordance with P850035 and was fully commercialized in 1987. Since then, over 100,000 devices have been implanted.
