2. The surgical device of claim 1 , wherein the copolymer comprises a styrene ethylene butylene styrene (SEBS) copolymer.
3. The surgical device of claim 1 , wherein the silicone oil has a viscosity from about 1 to about 50 centistokes.
4. The surgical device of claim 3 , wherein the silicone oil has a viscosity of about 5 centistokes.
5. The surgical device of claim 3 wherein the gel material comprises by weight at least about 6:1 mineral oil to copolymer, and at least about 1:1 low viscosity silicone oil to copolymer.
6. The surgical device of claim 1 , wherein the gel material is opaque.
7. The surgical device of claim 1 , wherein the gel material is transparent.
8. The surgical device of claim 1 , wherein the device includes two opposed rollers disposed inside the trocar housing and configured to seal and roll relative to the trocar housing and configured to receive an instrument inserted between the two rollers and into the trocar.
9. The surgical device of claim 1 , wherein the device comprises a hand access device.
10. The surgical device of claim 1 , wherein the gel material further comprises a lubricious agent deposited on at least one surface of the gel material.
11. The surgical device of claim 10 , wherein the lubricious agent comprises a dry film.
12. The surgical device of claim 10 , wherein the lubricious agent comprises an anti-fogging agent.
13. The surgical device of claim 12 wherein the roller is configured to coat a laparoscope inserted into the trocar with the anti-fogging agent.
14. The surgical device of claim 10 , wherein the lubricious agent comprises a hydrophilic coating.
15. The surgical device of claim 10 , wherein the lubricious agent comprises a soap.
16. The surgical device of claim 1 , wherein the copolymer comprises a styrene ethylene ethylene propylene styrene copolymer (SEEPS) copolymer.
17. The surgical device of claim 1 , wherein the gel material comprises by weight at least about 6:1 mineral oil to copolymer.
18. The surgical device of claim 1 , wherein the gel material comprises by weight at least about 1:1 low viscosity silicone oil to copolymer.
19. The surgical device of claim 1 , wherein the gel material comprises by weight at least about 6:1 mineral oil to copolymer, and at least about 1:1 low viscosity silicone oil to copolymer.
20. The surgical device of claim 1 wherein the silicone oil has a viscosity from about 1 to about 15 centistokes.
21. A surgical device comprising:
a trocar including a seal housing at a proximal end of the trocar; and
a non-tacky gel component, the component being disposed in the seal housing at the proximal end of the trocar; the component being configured to move relative to the seal housing to create a seal inside the trocar; the gel comprising a copolymer, a mineral oil and a low viscosity silicone oil, wherein the gel material has an elongation of greater than about 1000%.
22. The surgical device of claim 21 , wherein the copolymer comprises a styrene ethylene butylene styrene (SEBS) copolymer.
23. The surgical device of claim 21 , wherein the copolymer comprises a styrene ethylene ethylene propylene styrene copolymer (SEEPS) copolymer.
24. The gel of claim 21 , wherein the silicone oil has a viscosity from about 1 to about 50 centistokes.
25. The surgical device of claim 21 , comprising by weight at least about 6:1 mineral oil to copolymer.
26. The surgical device of claim 21 , comprising by weight at least about 1:1 low viscosity silicone oil to copolymer.
27. The surgical device of claim 21 , comprising by weight at least about 6:1 mineral oil to copolymer, and at least about 1:1 low viscosity silicone oil to copolymer.
28. The surgical device of claim 21 wherein the silicone oil is incorporated in the gel to create a non-tack surface.
29. The surgical device of claim 28 wherein the silicone oil has a viscosity from about 1 to about 50 centistokes.
30. The surgical device of claim 21 wherein the gel material has a resistance to compression set.
