Abstract
A connector system is provided for a positional sensitive spinal cord stimulation apparatus using reflectometry which incorporates the ability to connect to current IPG's either in a percutaneous or laminectomy form and which utilizes a novel light to frequency converter to generate a stimulation voltage in wave form to effect spinal cord stimulation.
