Abstract
A medical device having a contact surface exposed repeatedly to bodily tissue is disclosed. The contact surface is coated with a silicone polymer and one or more non-silicone hydrophobic polymers. The preferred medical device is a surgical needle, and the preferred coating is a polydimethylsiloxane and polypropylene wax hydrocarbon mixture. The incorporation of the non-silicone hydrophobic polymer increases the durability of the coating on the device without sacrificing lubricity.
