The disclosure describes a medical electrical lead including bonding strip to bond an elongate electrode coil to an elongate lead body to reduce damage to the medical electrical lead during manipulation of the medical electrical lead. The elongate lead body extends from a proximal end to a distal end and includes a proximal portion and a distal portion. The elongate electrode coil surrounds at least part of the distal portion of the elongate lead body. The bonding strip extends axially along the elongate electrode coil and extends only partially around the circumference of the elongate electrode coil for at least part of the length of the bonding strip, where at least a portion of the bonding strip is bonded to the elongate lead body to fix a portion of the elongate electrode coil to the elongate lead body.

A device for providing treatment is disclosed. The device provides proper skin electrical conductivity while still being minimally invasive by adhering to the patient's skin that also implements safety measures that off-the-shelf electrode options do not have. This device includes a graphite powder-based skin counter electrode that has a graphite powder suspended in an electrolyte gel that allows for electrochemical conduction between the graphite particles in the graphite powder. The gel is spread over a first side of a hydrogel layer. A device housing is mounted on the hydrogel layer over the first side. The device housing contains the electrolyte gel and graphite powder, defines an opening or lead opening as well as an empty expansion chamber for gaseous anodic byproduct. A metallic wire or rod extends from the electrolyte gel and through the housing opening and connects to a potentiostat. The second side of the hydrogel layer is adhered to the skin of the patient. The graphite powder-based skin counter electrode device takes into account safety.

Limited-number-of-use neuromodulator apparatuses that may be comfortably worn on the skin of a user to non-invasively apply transdermal electrical stimulation (TES).
