Claim:
1. A method of making a tack-free gel for a surgical device, comprising the steps of: providing a mold defining a mold cavity; spraying the mold cavity with a plastic material; pouring a molten gel being at a molding temperature into the mold cavity; melting a layer of the plastic material of the mold cavity onto the molten gel by permitting the molten gel to contact the mold cavity; cooling the molten gel to form a solidified gel; and increasing thickness of the melted layer of plastic material by selecting a plastic material that has a melting temperature lower than the molding temperature of the molten gel and increasing the temperature differential between the melting temperature of the plastic material and the molding temperature of the molten gel.
