A catheter for use in neurosurgery is described. The catheter has a fine tube arranged for insertion into the brain parenchyma of a patient with an external diameter of not more than 1.0 mm, a hub and a stop surface operatively connecting the single fine tube and the hub, the stop surface allowing a distal end of the fine tube to be located at a desired target during insertion of the fine tube into the brain parenchyma. The catheter may be used in stereotactically targeting treatment of abnormalities of brain function, and for the infusion of therapeutic agents directly into the brain parenchyma. This is advantageous when a therapeutic agent would have widespread unwanted effects which could be avoided by confining the delivery to the malfunctioning or damaged brain tissue. |
