Abstract
A multi-lead electrode catheter for use in acute pain management and a method utilizing this device is provided. The electrode catheter has a plurality of longitudinally spaced electrodes, and a conduit for infusion of analgesic medications simultaneous with application of electrical stimulation to the epidural space of the spinal cord, such that three to four dermatome and myotome body regions are affected. The device is properly positioned without the aid of fluoroscopy in response to communication from the patient as to which dermatomes and myotomes are experiencing paresthesias caused by the electrical stimulation of the corresponding nerve fibers.
