The spinal cord stimulation leads are responsible for transmitting the electrical pulses generated by the neuromodulator to the electrodes which are located at the end of the leads. The leads are thin wires that are inserted via a needle into the epidural space.
The leads can be paddle leads or percutaneous leads. Paddle leads have a large "paddle-shaped" head that provide more extensive coverage. Percutaneous leads are slim and easy to manoeuvre through the epidural space.
