Abstract
Official abstract text for this publication.
An implant for deep brain stimulation (DBS) has an array of electromagnetic microcoils dispersed over the length of the implant. The microcoils produce magnetic fields that are directed into, and induce current in, the adjacent brain tissue. The microcoils may be selectively operated to direct and focus electrical stimulation to targeted areas of the brain. The implant is useful in studying or treating neurophysiological conditions associated with the deep regions of the brain such as Parkinson's disease, drug addiction, and depression.
First claim
Opening claim text (preview).
We claim: 1. A device for stimulating biological tissue, the device comprising: an insertable implant extending along a longitudinal axis from a proximal portion to a distal portion; a plurality of electrical conductors extending along the longitudinal axis of the implant; a plurality of microcoils proximate to the distal portion of the implant, each of the microcoils being coupled to at least one of the electrical conductors; an electrically isolating barrier completely cov…
