Abstract
An apparatus, a system and methods for modulating and monitoring tissue have an elongate member with proximal and distal ends and a plurality of annular stimulating electrodes axially arranged along the elongate member. The stimulating electrodes are disposed near the distal end and are adapted to pass current into tissue. At least one of the annular stimulating electrodes has at least three independent stimulation points on the electrode. The apparatus also includes a plurality of recording electrodes that are adapted to measure local tissue potentials and a plurality of conductors are coupled with the recording and stimulating electrodes. An optional multiple contact connecting terminal may be coupled with the conductors and is disposed near the proximal end of the elongate member.

2. An apparatus for stimulating and monitoring tissue, the apparatus comprising:
-
an elongate member having a longitudinal axis, a circumference, a proximal end, a distal end, and a central lumen extending between the proximal end and the distal end of the elongate member, the central lumen sized to receive a stylet for advancement of the elongate member slidably thereover; a plurality of stimulating regions coupled with the elongate member, the stimulating regions arranged along the elongate member and axially spaced apart along the longitudinal axis, the stimulating regions disposed near the distal end, the stimulating regions being adapted to pass current into the tissue, and wherein at least one stimulating region consists of three independent stimulation sites, each stimulating site having one stimulation electrode, the stimulation sites spaced apart from one another and separated from one another by an insulating material so that each stimulation site may be stimulated independently of the other stimulation sites; and a first plurality of conductors electrically coupled with the stimulation electrodes. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 22)

12. A method of treating tissue comprising:
-
providing a lead having at least one stimulating region and as central lumen with a stylet slidably disposed therein; implanting the lead in tissue, wherein the at least one stimulating region consists of three stimulation sites, each stimulation site having one stimulation electrode, the three stimulation sites arranged in a broken ring separated from one another by an insulator so that each stimulation electrode may be stimulated independently of the other stimulation electrode; stimulating a volume of tissue with a therapeutic electrical current from a first group of the three stimulation sites; and steering the therapeutic electrical current through the tissue by independently changing magnitude of the therapeutic electrical current delivered by the first group or by delivering the therapeutic electrical current from a second group of the three stimulation sites different than the first group. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
