Abstract
An implantable medical electrode lead for stimulation of bodily tissue. The lead is adapted for use with a needle lumen diameter of not greater than 0.05 inch, and includes a lead body and a tine assembly. The lead body has a distal section forming at least one exposed electrode surface. The tine assembly includes a plurality of tines each having a base end coupled to an exterior of the lead body immediately adjacent the exposed electrode surface and a free end that is movable relative to the lead body to inhibit axial migration of the lead body upon implantation into a patient. In one embodiment, the lead body is a PNE lead and provides two electrode surfaces for bipolar operation.
