How does the SpF® Stimulator Work?

The SpF® Implantable Spine Fusion Stimulator produces a direct current signal at the fusion site, is designed to mimic the body�s natural healing mechanism, that signals for bone growth to occur. Two thin wires known as "cathodes" are connected to a low-profile electrical generator near your surgical site. Upon implantation, the SpF® Stimulator is automatically activated and begins to deliver therapeutic treatment. The SpF® Stimulator requires no maintenance during the course of your treatment and is virtually unnoticeable. Clinical investigations have shown that the SpF® Implantable Spine Fusion Stimulator increases the probability of fusion success rates, particularly in patients with specific risk factors(1, 2, 3, 4).
