Abstract
The neural stimulating lead includes a hollow lead body and an active fixation stabilizing structure. The stabilizing structure comprises two pairs of laterally projecting vanes and an extendable membrane on a dorsal surface of the lead body adapted to be extended to apply pressure against a dorsal surface of a vertebra to force and hold an electrode on the opposite surface of the lead body against the dura of the spinal cord. The membrane forms a canopy which is extended by causing an expandable material to expand against the membrane when actuated by an actuating material inserted into the lead body.
