Patent ID: 7904149

Claim:
A method comprising: introducing a medical elongated member into a body of a patient; advancing the medical elongated member to a target tissue site proximate to at least one of an occipital nerve or a trigeminal nerve within the body of the patient, wherein the elongated member defines an outer surface comprising a first outer surface portion and a second outer surface portion extending around at least approximately ten percent of an outer perimeter of the elongated member, the first and second outer surface portions being aligned at and sharing an axial position along a longitudinal axis or the elongated member, and the elongated member further comprising a first fixation element extending a first distance from the first outer surface portion and a second fixation element extending a second distance from the second outer surface portion, the first distance being greater than the second distance, and wherein a longitudinally-extending section of the second outer surface portion proximate to a distal end of the elongated member is substantially devoid of any fixation elements that extend the first distance from the second outer surface portion; and orienting the second fixation element in a substantially superficial direction.
