Patent ID: 8666507

Claim:
A deployable probe for stimulating deep brain tissue comprising: a shaft having a proximal end, a distal end, and a hollow section; at least one opening on said shaft, said opening configured for connecting the hollow section to adjacent brain tissue; at least one extendable tendril of a plurality of tendrils with a proximal end and a distal end, said at least one extendable tendril configured to selectively move from a first position contained within the hollow section to a second position adjacent said brain tissue, said at least one extendable tendril configured to stimulate said brain tissue and wherein said at least one extendable tendril is configured to selectively extend until said at least one extendable tendril's stimulation coincides with a target within said brain tissue, and; a deployer linked to said plurality of tendrils, said deployer configured to independently move said at least one extendable tendril from said first position to said second position, and wherein the deployer further comprises a fluid-actuated deployment system comprising at least one fluid line having a proximal end and a distal end, the distal end of the fluid line attached to one of said plurality of tendrils and the proximal end to an actuation reservoir.
