A new minimally invasive technique for lead revision of perc-paddle leads.

Abstract

To report on a less-invasive technique for replacing a broken lead in a spinal cord stimulation (SCS) device that makes use of St. Jude Medical's "Epiducer" device. A 53-year-old woman suffered a loss of stimulation on her internal pulse generator (IPG), which was found to have a broken lead. The broken lead was withdrawn using the Epiducer device with minimal invasiveness and without pain. A new lead was put in place, and successful stimulation using the IPG resumed. Follow-up 3 weeks later showed a well-functioning SCS system. An Epiducer can be used to revise the SCS system in a minimal invasive way without a new puncture. Follow-up study of this technique as well as others for revising an SCS system should be encouraged and used in comparison study.
