Abstract
A lead assembly for an implantable medical device includes a lead body having a proximal end and a distal end. One or more connectors at the proximal end of the lead body are each adapted for connection to a pulse generator. One or more conductive elements are coupled to the one or more connectors at the proximal end and extend through the lead body to the distal end. Each of the one or more conductive elements includes an electrode coil that extends from the distal end of the lead body that is formed into a helix having a diameter greater than a diameter of the electrode coil.
