Abstract
Apparatus and associated methods relate to a lead that includes metallic traces sandwiched between layers of polymers to form a ribbon (e.g., similar to a flex circuit). In an illustrative example, areas on both ends of the traces may be exposed, forming stimulation electrodes on one end and electrical contacts on the other. The ribbon may be formed such that it fits down a small diameter needle. When the needle is removed, the formed ribbon may relax and engage the tissue providing a means of retention. The lead may advantageously: (1) be minimally invasive to implant, (2) be inexpensive, (3) stay in place a temporary/trial medical procedure setting, and (4) be easy to remove.
