Abstract
Abstract A method of using a sheet of silicone rubber with one smooth, tacky side as a non-slip surface for one or more articles. The sheet is placed on the surface of an object, and articles to be supported are placed on the smooth, tacky side of the sheet. The articles will not slide off the sheet despite inclination or movement of the object surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A method of supporting and retaining surgical instruments on a surface which is at least in part not flat or horizontal, comprising: forming a flexible sheet of predetermined dimensions from methyl vinyl polysiloxane containing small amounts of ground silica filler, said sheet having two sides, one side being smooth, said smooth side having an inherently tacky surface of the type that is formed when the polysiloxane is cured with said smooth side exposed to air, and having relatively high kinetic and static coefficients of friction; placing said sheet on said surface with said smooth tacky side of said sheet facing upwardly; and placing a surgical instrument on said smooth tacky surface whereby said instrument is supported thereon and does not slip or slide therefrom.
Claim 2
Independent Claim
124 words
A method of supporting and retaining surgical instruments on a surface which is at least in part not flat or horizontal, comprising: forming a flexible sheet of predetermined dimensions from methyl vinyl polysiloxane containing small amounts of ground silica filler, said sheet having two sides, one side being smooth, said smooth side having an inherently tacky surface of the type that is formed when the polysiloxane is cured with said smooth side exposed to air, and having relatively high kinetic and static coefficients of friction; placing said sheet on said surface with said smooth tacky side of said sheet facing upwardly; and placing a surgical instrument on said smooth tacky surface whereby said instrument is supported thereon and does not slip or slide therefrom.
Claim 3
Dependent Claim
17 words
The method according to claim 1, wherein the other side of said sheet has a textured surface.
Claim 4
Dependent Claim
25 words
The method according to claim 1, wherein said sheet of methyl vinyl polysiloxane has a thickness of from about 0.025 inch to about 0.035 inch.
Claim 5
Dependent Claim
42 words
The method according to either claim 1 or 2 wherein said surface is the surface of a surgical drape overlying a patient and wherein said sheet may be subjected to washings and sterilization without substantial loss of its inherent tacky surface qualities.
Claim 6
Dependent Claim
16 words
The method according to claim 1, wherein said instrument is pressed against said smooth tacky side.
Claim 7
Dependent Claim
18 words
The method according to claim 1, wherein said surface is inclined at a slope of greater than 30°.
Claim 8
Dependent Claim
17 words
The method according to claim 5, wherein said surface is inclined at a slope of about 90°.
Claim 9
Dependent Claim
31 words
The method according to claim 1, wherein the ground silica filler is present in an amount of from about 10 to about 50 parts per 100 parts of methyl vinyl polysiloxane.
