The aim of this paper is to illustrate the proposed idea by Mr. Abdulwhab Alahmari in the paper entitled “Proposal of a Cleanable VP Shunt for Hydrocephalus” [1]. This illustration will highlight the invention’s important details and illustrate the fundamental parts of the proposed VP shunt (Figure 1-8).
Figure 1: Illustration of the cleanable VP shunt. 1) Entering points; 2) Siphon shaped catheter; 3) Stainless steel catheter; 4) Cleaning access to the abdomen;
5) Cleaning access to the head; 6) PMMA covers the catheter from outside; 7) To the brain catheter; 8) One direction valve; 9) To the abdomen catheter; and 10)
PMMA covers the catheter from inside.

Figure 3: The distal part of the abdominal part of the shunt. 12) Secondary openings to allow the flow from inside to outside; 13) The distal end; 14) The primary
opening at the end of the catheter, and 15) The secondary openings are designed (convergence) to allow the flow from inside the shunt to outside the shunt and
it prevent the flow back.

Figure 5: The required position from the neurosurgeon to place the shunt in a superior position as seen in this illustration. 19) The shunt position allows the entrance
point to be in a superior position.
