Abstract
Devices and methods for implanting leads along a spinal cord include an introducer having a main body defining a lumen and one or more collapsible and expandable side sheaths attached to the main body. The side sheaths may be collapsed as the introducer is positioned in a desired location of a patient to maintain a low profile. Once the introducer is placed, the side sheaths may be expanded to receive a lead. A lead may also be inserted through a lumen of the main body. Once the leads are inserted, the introducer may be withdrawn over the leads, leaving the leads implanted in the desired region in a desired orientation.
