Abstract
The present invention provides systems, apparatus and methods for selectively applying electrical energy to body tissue. More specifically, systems and methods are provided for introducing a spinal cord stimulation electrode device into a patient's epidural space through a small portal, such as a percutaneous penetration, and then expanding the electrode device once inside the epidural space to achieve a larger footprint of contact on the dura. This substantially prevents migration of the electrode within the epidural space and provides for more efficient and effective treatment.
