Patent ID: 8583257

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 the distal end of said shaft, said opening configured to connect the hollow section to adjacent brain tissue; and a plurality of extendable tendrils, each with a proximal end and a distal end, each said tendril configured to selectively move from a first position contained within the hollow section to a second position adjacent said brain tissue, said tendril configured to deliver treatment to the brain tissue; a deployer linked to said tendrils, said deployer configured to independently move the tendrils from said first position to said second position, and wherein the deployer further comprises a fluid-actuated deployment system comprising a plurality of fluid lines, each line with a proximal end and a distal end, the distal end of each fluid line attached to one of said tendrils and the proximal end connected to an actuation reservoir.
