Abstract
An implantable lead having at least one electrode contact at or near its distal end prevents undesirable movement of the electrode contact from its initial implant location. One embodiment relates to a spinal cord stimulation (SCS) lead. A first injectable material is injected into the dura space to mechanically position the electrode array with respect to the spinal cord. Conjunctively for use with adhesives, or alternatively for use instead of the adhesives, a balloon may be positioned on the electrode lead array. The balloon is filled with air, liquid or a compliant material. When inflated, the balloon stabilizes the lead with respect to the spinal cord and holds the lead in place. An elastic aspect of the balloon serves as a contained relief valve to limit the pressure the balloon may place on the surrounding tissues when the epidural space is constrained.
