Catheter guide and drill guide apparatus and method for perpendicular insertion into a cranium orifice
First Claim
1. A catheter guide and drill guide apparatus for allowing visualization and access to a catheter, comprising, a drill guide and a catheter guide, said drill guide comprising a tubular member defining a central lumen to permit the passage there through of a drill and to allow for the insertion therein of said catheter guide, said tubular member having a drill guide slot;
- and said catheter guide, comprising a catheter tubular member defining a catheter guide opening to permit the passage there through of said catheter, said catheter tubular member having a catheter guide slot, whereby the catheter guide slot is alignable with the drill guide slot, thereby allowing the operator to visualize and have access to the catheter when said catheter is inserted in said catheter guide and when the catheter guide slot is aligned with the drill guide slot, and allowing for the removal there through of the catheter.

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.
