Neural stimulation delivery device with independently moveable delivery structures
First Claim
1. A stimulation delivery device for stimulating neural tissue comprising:
- a body having a proximal end and a distal end and defining a plurality of ports along the longitudinal axis thereof between the proximal end and the distal end of the body;
a plurality of leads insertable within the body, each of the plurality of leads independently extendable through a respective one of the plurality of ports and;
a control mechanism in communication with the plurality of leads to independently extend each of the plurality of leads through a respective one of the plurality of ports with respect to each other of the plurality of leads,wherein each of the plurality of leads has at least two electrodes thereon and each electrode is selectively powerable,wherein the control mechanism comprises a gear and clutch assembly.

Abstract
The present invention relates to a neural stimulation delivery device to deliver electrical and/or chemical stimulation to target sites in the central and peripheral nervous system. The device generally includes a tubular body defining a plurality of ports along the longitudinal axis thereof, a plurality of delivery structures insertable in the body, and a control mechanism in communication with the plurality of delivery structures to independently move each of the plurality of delivery structures through a respective one of the plurality of ports with respect to each other of the plurality of delivery structures. The ability of each delivery structure to be independently moveable through a respective port allows each delivery structure to be selectively advanced or retracted independent of the movement of another delivery structure.
