Abstract
The assembly and method of the present invention guides the insertion of a medical device, such as a guide wire, into the subdural space surrounding the brain of a vertebrate. Preferably, the assembly is dimensioned to guide insertion of the medical device in a direction substantially tangent to the curvature of the brain. Further preferably, the assembly would allow its removal from the subdural space without disturbance of the location of the medical device. Still further preferably, the assembly will help to protect the brain from injury during insertion of the medical device into the subdural space.
