OPERATIVE PROCEDURES

• Spinal Cord Stimulator Implant

A small wire (called a lead) connected to a power source is surgically implanted under the skin. Low-level electrical signals are then transmitted through the lead to the spinal cord or to specific nerves to block pain signals from reaching the brain. Using a magnetic remote control, you can turn the current on and off, or adjust the intensity. The sensations derived from the stimulator are different for everyone; however, most patients describe it as a pleasant tingling feeling.
There are two kinds of systems available in spinal cord stimulation. The more commonly used system is a fully implanted unit that utilizes a pulse generator and a non-rechargeable battery that must be replaced over time. The second system relies on radio frequency and includes a transmitter and an antenna, which are carried outside the body (much like a pager or cell phone) and a receiver, which is implanted inside the body. Your physician will help you determine which system is better for you based on your condition, your lifestyle, and how much electrical energy is required to provide you with adequate pain relief.
