A method of manufacturing a cranial shock absorption system. The method is comprised of forming a first layer of elastomer, positioning a thin layer of material on top surface of elastomer such that the top surface is exposed around the entire exterior of the layer of material, allowing the first layer to partially set, positioning a tubular stem or valve on the first layer adjacent to the layer of material, forming a second layer of elastomer, allowing the first layer and second layer of elastomer to fully set around the thin layer of material, removing the thin layer of material from between the first and second layers of elastomer and then introducing a fluid into the chamber through the tubular stem.

1. A method of manufacturing a shock-absorbing bladder, the method comprising: forming a first layer of elastomer having a top surface;allowing said first layer to partially set;positioning a thin layer of material having an outer edge on said top surface of said first layer of elastomer, wherein a surface area of a bottom surface of said layer of material is less than the surface area of the top surface of said first layer of elastomer material, and wherein said thin layer of material is positioned such that a portion of the top surface is exposed around at least a substantial portion of the outer edge of said thin layer of material;forming a second layer of elastomer over said first layer and said thin layer of material;allowing said first layer and said second layer to fully set around said thin layer of material to form a body having an outer surface;removing said thin layer of material from between said first layer of elastomer and said second layer of elastomer to form a chamber therebetween; andintroducing a fluid into said chamber. 2. The method of claim 1 further comprising: creating an opening from said outer surface of said body to said thin layer of material; andwherein said step of removing said thin layer of material is performed by pulling said thin layer of material from between said first and second layers of elastomer through said pathway and said an opening. 3. The method of claim 2 further comprising: positioning an end of a tubular stem through said opening; andfixing said tubular stem to said body. 4. The method of claim 3 further comprising sealing said tubular stem to prevent egress of said introduced fluid from said chamber. 5. The method of claim 1 wherein said thin layer of material comprises a tab, and wherein said step of positioning said thin layer of material further comprises locating an end of said tab at an outer edge of said top surface of said first layer of elastomer so that said tab is adjacent the outer surface of said body. 6. The method of claim 5 wherein said step of removing said thin layer of material is performed by pulling said thin layer of material from between said first and second layers of elastomer by said tab of material and thereby creating an opening from said chamber to said outer surface of said body. 7. The method of claim 6 further comprising: positioning an end of a tubular stem through said opening; andfixing said tubular stem to said body. 8. The method of claim 7 further comprising sealing said tubular stem to prevent egress of said introduced fluid from said chamber. 9. The method of claim 1 wherein the pressure within said chamber following said step of introducing a fluid is between five and fifteen psig, inclusive. 10. The method of claim 1 further comprising mixing an antibacterial agent into said elastomer. 11. The method of claim 10 wherein said antibacterial agent is polychloro phenoxy phenol. 12. The method of claim 11 wherein the ratio of antibacterial agent to elastomer is 1:40 by volume. 13. The method of claim 1 wherein said elastomer is a platinum cure silicone compound. 14. The method of claim 1 wherein said thin layer of material is a biaxially-oriented polyethylene terephthalate film. 15. The method of claim 1 wherein said fluid is air. 16. The method of claim 9 wherein said fluid is air. 17. The method of claim 1 wherein said elastomer is a silicone elastomer. 18. The method of claim 17 further comprising: creating an opening from said outer surface of said body to said thin layer of material; andwherein said step of removing said thin layer of material is performed by pulling said thin layer of material from between said first and second layers of silicone elastomer through said pathway and said an opening. 19. The method of claim 18 further comprising: positioning an end of a tubular stem through said opening; andfixing said tubular stem to said body. 20. The method of claim 19 further comprising sealing said tubular stem to prevent egress of said introduced fluid from said chamber.
