According to one embodiment, a neurological stimulation lead is adapted
for implantation proximate target nerve tissue in a person for
neurological stimulation of the target nerve tissue. A resilient lead
body has a generally spiral natural configuration. A plurality of
electrodes are located along the resilient lead body and adapted to be
positioned proximate the target nerve tissue and to deliver electrical
stimulation pulses to the target nerve tissue. The plurality of
electrodes are located along the resilient lead body such that the
electrodes are arranged in a predetermined array when the resilient lead
body is in its generally spiral natural configuration. An inner channel
formed through the resilient lead body is adapted to receive a
straightening element. When inserted into the inner channel, the
straightening element is adapted to place the resilient body in a
generally linear configuration for insertion of the lead into the person
and positioning of the electrodes proximate the target nerve tissue. The
resilient lead body is adapted to return to its generally spiral natural
configuration upon removal of the straightening element from the inner
channel after insertion of the lead and positioning of the electrodes
proximate the nerve tissue.
