Abstract
The present invention provides for an improved apparatus and method for electrical stimulation. A paddle having a thickness up to 0.030 inches is implanted adjacent the spinal cord dura mater to reduce the likelihood of paralysis due to stress on the spinal cord attributed to bulkier leads. The paddle is then positioned so that at least one of a plurality of electrodes is positioned over the area of the spinal cord requiring pain treatment; and then electric stimulation is applied to the electrodes to effect pain treatment. In another embodiment the paddle is curved about a vertical axis to substantially match the shape of a human spinal cord dura mater to help reduce lead migration.
