Patent ID: 7972308

Claim:
A catheter assembly for intracranial treatment of a tissue region of the brain of a patient comprising: an outer catheter having an exterior surface extending between a proximal end and a distal end for positioning within the tissue region of the brain, an inflatable balloon mounted upon the exterior surface, elements distal to the balloon, at least one aperture and a lumen, the elements being adapted to monitor electrical changes in brain activity within the tissue region, to electronically stimulate the tissue region, and to provide information on a precise position of the elements when the elements are located entirely within the brain and being mounted proximal to the distal end of the outer catheter upon an exterior surface of a distal portion of the outer catheter; and an inner catheter sized to be received within the lumen and having a passageway extending between a proximal end and at least one port for positioning within the tissue region of the brain, the lumen being adapted to guide the inner catheter to the tissue region.
