Electrode assembly for spinal cord stimulation
First Claim
1. An electrode assembly for stimulation of a spinal cord within a spinal canal, the spinal canal containing a dura mater dorsally overlying the spinal cord, said assembly comprising:
- (a) a base having an anterior and posterior ends, having lateral and oppositely lateral sides, and having dorsal and ventral sides;
(b) a lateral arm having anterior and posterior ends, having dorsal and ventral sides, and having proximal and distal ends, wherein said arm'"'"'s proximal end is fixedly attached to the base'"'"'s lateral side;
(c) a ventral series of electrodes fixedly attached to a surface selected from the group consisting of the base'"'"'s ventral side and the lateral arm'"'"'s ventral side;
(d) a dorsal series of electrodes fixedly attached to a surface selected from the group consisting of the base'"'"'s dorsal side and the lateral arm'"'"'s dorsal side;
(e) ventral and dorsal matrices of electrical conductors, said matrices respectively communicating electrically with the ventral and dorsal series of electrodes; and
(f) means for electrifying the ventral and dorsal matrices of electrical conductors, said means being adapted for, upon a rotation stopping contact by the distal end of the lateral arm against the dura mater, exclusively electrifying the ventral matrix of electrical conductors, said means being further adapted for, upon a counter-rotation stopping contact by the distal end of the lateral arm against the dura mater, exclusively electrifying the dorsal matrix of electrical conductors.

Abstract
An electrode assembly for stimulation of a spinal cord within a spinal canal, the spinal canal containing a dura mater, the assembly incorporating a base, a lateral arm extending from the base; a ventral series of electrodes attached to base and to the lateral arm; a dorsal series of electrodes attached to the base and to the lateral arm; ventral and dorsal matrices of electrical conductors respectively communicating electrically with the ventral and dorsal series of electrodes; and an electric pulse generator for electrifying the ventral and dorsal conductors, the generator being adapted for exclusively electrifying the ventral matrix of electrical conductors, and for alternatively exclusively electrifying the dorsal matrix of electrical conductors.
