Abstract
A medical lead includes a lead body having a proximal end for electrical connection to an implantable electric signal generator and a distal end portion having a plurality of electrodes extending in a helical manner longitudinally along the distal end portion. Adjacent helical electrodes may be offset, for example, 90 degrees or 180 degrees. The helical electrodes may extend less than, greater than, or 360 degrees. The electrode arrangement provides increased surface area, improving the capability of positioning the lead against the nerve as desired.
