Glossary Term
Spinal Cord Stimulator (SCS)
Definition
A spinal cord stimulator (SCS) is a medical device that is implanted in the body to help manage chronic pain, particularly for conditions such as failed back surgery syndrome, complex regional pain syndrome, and neuropathic pain. The device delivers low-voltage electrical impulses to the spinal cord through a lead placed near the spinal cord. These electrical signals alter pain signals traveling to the brain, effectively masking or reducing the sensation of pain. SCS devices typically consist of an implantable pulse generator (IPG), which produces the electrical impulses, and one or more leads with electrodes that are implanted near the spinal cord. The patient can control the intensity and location of the stimulation through an external remote device.
Relevance to the MedTech Industry
Spinal cord stimulators represent a significant advancement in pain management, providing an option for patients who do not respond to traditional pain treatments such as medication or physical therapy. The technology behind SCS devices has improved over time, with advancements in miniaturization, wireless control, and the ability to precisely target specific areas of pain. As the prevalence of chronic pain conditions rises, the demand for innovative solutions like spinal cord stimulators continues to grow. These devices are subject to regulatory oversight by agencies like the FDA, which require manufacturers to demonstrate the safety and efficacy of the device through clinical trials and post-market surveillance. SCS devices also present opportunities for ongoing research and development to improve patient outcomes and address new pain management needs.

Examples of Spinal Cord Stimulator Applications
Chronic Pain Management:Spinal cord stimulators are commonly used for patients with chronic pain conditions such as failed back surgery syndrome or complex regional pain syndrome. The device provides pain relief by altering pain signals before they reach the brain.
Neuropathic Pain Relief:SCS is also used to treat neuropathic pain, which arises from nerve damage or dysfunction. This type of pain is often resistant to conventional pain management methods, making SCS a viable alternative.
Post-Surgical Pain Management:Spinal cord stimulators are used to manage pain following complex surgeries, such as spinal fusion or joint replacement, when pain is difficult to control with standard treatments.
