Abstract

A cerebral spinal fluid shunt plug includes a shunt plug housing having a shunt valve recess formed therein and a window recess with an access hole. The cerebral spinal fluid shunt plug also includes a shunt valve shaped and dimensioned for positioning within the shunt valve recess of the shunt plug housing and a lucent disk shaped and dimensioned for the passage through the central access hole of the shunt plug housing. In another embodiment, a cerebral spinal fluid shunt plug includes a shunt plug housing having a shunt valve recess formed therein and an intracranial monitoring device recess with an access hole. A shunt valve is positioned within the shunt valve recess of the shunt plug housing and an intracranial monitoring device is passed through the central access hole of the shunt plug housing.

Claims (14)

1 . A cerebral spinal fluid shunt plug assembly, comprising:

a shunt plug housing including a shunt valve recess, the shunt plug housing also includes access holes or passageways allowing the shunt valve recess to communicate with an exterior of the shunt plug housing, the access holes or passageways being shaped and dimensioned to allow for connection of a ventricular catheter and a peritoneal catheter with a shunt valve housed within the recess of the shunt plug housing;

a shunt valve shaped and dimensioned for positioning within the shunt valve recess of the shunt plug housing; and

a lucent element shaped and dimensions for positioning adjacent to the shunt plug housing.

2 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element is a clear custom intercranial implant.

3 . The cerebral spinal fluid shunt plug assembly according to claim 2 , wherein the clear custom intercranial implant includes an implant body having an outer first surface, an inner second surface, and a peripheral edge extending between the outer first surface and the inner second surface.

4 . The cerebral spinal fluid shunt plug assembly according to claim 2 , wherein the implant body comprises PMMA (Poly(methyl methacrylate).

5 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element is optically transparent.

6 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element is optically translucent to all light waves.

7 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element is sonolucent.

8 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element is radiolucent.

9 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element is optically transparent, optically translucent to all light waves, is sonolucent, and is radiolucent.

10 . The cerebral spinal fluid shunt plug assembly according to claim 1 , wherein the lucent element includes an implant body with the mating segment formed with a relatively concave profile shaped and dimensioned to mate with the shunt plug housing.

11 . The cerebral spinal fluid shunt plug assembly according to claim 10 , wherein the mating segment includes a concave cut-out along a central segment thereof.
