Abstract
A needle or puncture guard that has inherent probe directing features for use in an in-line configured shunt valve is provided. The guard comprises a base member configured for mounting within the domed reservoir of the shunt valve, and a guide wall seated on the base member. The guide wall is defined by a top wall, an inner side wall, and an opposed outer side wall. The inner side wall has an indented section with an aperture extending through the indented section. The inner side wall can be concavely curved, while the indented section has a curvature that directs instruments that are pressed against the guide wall towards the aperture. A
method for performing catheter revisions on a shunt system having a guard within the shunt valve is provided as well. Also provided is a method for placement of an intracranial pressure sensor percutaneously into a ventricular catheter for determining intracranial pressure.

Claims (25)
1. A puncture guard for use in a shunt valve having a domed silicone reservoir, comprising:
a base member configured for mounting within the domed silicone reservoir of the shunt valve; and a guide wall seated on the base member, the guide wall being defined by a top wall, an inner side wall, and an opposed outer side wall, the inner side wall having thereon an indented section and an aperture extending through the indented section.
a base member configured for mounting within the domed silicone reservoir of the shunt valve; and a guide wall seated on the base member, the guide wall being defined by a top wall, an inner side wall, and an opposed outer side wall, the inner side wall having thereon an indented section and an aperture extending through the indented section.
2. The guard of claim 1, wherein the inner side wall is concavely curved.
3. The guard of claim 2, wherein the guide wall is C-shaped.

22. A method of performing a percutaneous catheter revision on a shunt system having a blocked ventricular catheter, comprising the steps of providing a shunt system having a shunt device with a valve mechanism therein for regulating fluid flow into and out of the shunt device, an inlet port connected to a ventricular catheter, an outlet port connected to a drainage catheter, and a domed reservoir in fluid communication with the inlet port, the domed reservoir further including a puncture guard having a base member and a guide wall seated on the base member, the guide wall being defined by a top wall, an inner side wall, and an opposed outer side wall, the inner side wall having thereon an indented section and an aperture extending through the indented section;
surgically exposing the domed reservoir;
puncturing the domed reservoir with a catheter needle;
threading a flexible endoscopic instrument through the catheter needle;
inserting a tip of the flexible endoscopic instrument through the aperture;
and extending the tip of the flexible endoscopic instrument into the ventricular catheter.
