1. A deployable probe configured 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 for connecting 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; and
a fluid-actuated deployer linked to said tendrils, said deployer configured to independently move each tendril with respect to the other tendrils from said first position to said second position.
