IMPLANTABLE LEADS WITH FLAG EXTENSIONS

摘要

In one example, an implantable lead includes a substrate and an electrically conductive material disposed on the substrate to form a flexible circuit. The flexible circuit includes a proximal end adapted to electrically connect to an implantable processor, a distal portion adapted to stimulate a cochlear nerve, and a lead body extending from the proximal end to the distal portion, the lead body having a longitudinal axis and comprising a plurality of electrical traces adapted to carry electrical signals from the proximal end to the distal portion. A flag extension is formed in the substrate and extends laterally outward from the lead body longitudinal axis. A method for forming a cochlear lead with a flag extension is also provided.
