Abstract

A depth probe for intracranial treatment is provided having a body that includes a distal portion with one aperture and at least one element mounted upon the exterior surface, a lumen defined by the body that is accessed only through the aperture and an opening, and a proximal portion with at least one proximal-contact radially circumscribing the body. The proximal-contact is conductively connected with the element. The lumen is sized to receive coaxially an inner catheter adapted to transfer a fluid such as a drug with a tissue region within the patient's brain. The aperture is coaxial with the lumen and sized to allow the inner catheter to pass through it. The depth probe preferably includes an inflatable balloon secured upon its distal portion proximal to the element. The balloon is adapted to seal upon inflation the tract created by the probe when inserted into the brain.
