Abstract
An improved apparatus for drilling an orifice in a human cranium at an angle of substantially 90 degrees to a plane defined by a tangent to the surface of the cranium at the orifice and for guiding ventricular catheter placement. The apparatus has a first tubular guide for directing a drill at the proper angle, the first tubular guide being supported upon the cranium by a plurality of leg members and having a slot or opening which allows for visualization of the drilling point. The invention further includes a second tubular guide for directing a catheter into the ventricular portion of the patient's brain. The second tubular guide, has a slot or opening which allows for pre-loading of the catheter. The second tubular guide inserts within the first tubular guide and receives the catheter and directs it into the ventrical. The slotted design of the first and second tubular guides allow the guides to be removed from the side of the catheter rather than over the end of the catheter.
