1. A medical electrical lead for stimulating a nerve, wherein the lead is adapted to be delivered to a stimulation site within a vessel adjacent the nerve to be stimulated, the lead comprising;

  • a proximal end adapted to be connected to a pulse generator;

    a lead body including a distal portion adapted to transition between a collapsed configuration and an expanded configuration for securing and stabilizing the lead at the stimulation site, wherein the distal portion comprises a first spiral, a second spiral, and a generally straight portion occurring between the first spiral and the second spiral, wherein the spirals have a predetermined effective outer diameter and are adapted to frictionally engage at least one vessel wall; and

    one or more electrodes adapted to deliver an electrical pulse transvascularly to the nerve to be stimulated located on the distal portion, wherein when the distal portion expands at least one electrode is placed in close proximity to the nerve to be stimulated.
