LONG TERM EFFECTS OF SPINAL CORD STIMULATION

"Patients are already implanted with device from the H-49023 study.~The SCS implantation technique consists of inserting epidural leads-containing multiple stimulating electrodes (8). Two leads will be implanted percutaneously into the epidural space.~The implantable pulse generator (IPG) is a neurostimulation system designed to deliver low-intensity electrical impulses. The system is intended to be used with leads and extensions that are compatible with the system. This neurostimulation system is indicated (FDA approved) as an aid in the management of chronic, intractable pain of the trunk and/or limbs. The intended use in this study is considered experimental."
