LEAD AND METHODS FOR BRAIN MONITORING AND MODULATION

摘要

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.

主权项

1. An electrical stimulation lead, comprising:
an elongate body having a circumference, a proximal portion, a distal portion, and a distal tip; at least two stimulating regions longitudinally spaced-apart from, each other and disposed along the distal portion of the elongate body, each stimulating region comprising at least three independent stimulation electrodes arranged around the circumference of the elongate body and first insulating material disposed between the stimulation electrodes; a distal stimulating electrode disposed at the distal tip of the elongate body; second insulating material extending distally from the at least two stimulating regions and separating the distal stimulating electrode from the at least two stimulating regions; and a plurality of conductors electrically coupled with the stimulation electrodes and the distal stimulating electrode.
