System, method, and resilient neurological stimulation lead for stimulation of a person's nerve tissue
First Claim
1. A neurological stimulation lead adapted for implantation proximate target nerve tissue in a person for neurological stimulation of the target nerve tissue, comprising:
- a resilient lead body having a generally spiral natural configuration, the spiral natural configuration comprising multiple turns;
a plurality of electrodes 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 being 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, spacings between adjacent electrodes of the plurality of electrodes being varied between respective turns of the spiral natural configuration; and
an inner channel formed through the resilient lead body and adapted to receive a straightening element, when inserted into the inner channel the straightening element 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 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.

Abstract
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.
