Abstract
This invention relates to a new water soluble lubricant for a medical device, such as a catheter and an introducer needle. The lubricant is a silicone based water soluble compound. Preferably, a silicone surfactant is used such as a block copolymer polyalkylene oxide-modified polydimethylsiloxane. Alternatively, an alkylene oxide modified silicone glycol may be used as the lubricant. In addition, lecithin can be added as a lubricant. The lubrication solution includes a solution stabilizer to clarify the solution and antimicrobial agents to inhibit microbial growth in the water solution or on the coated product. Vitamin E or its derivatives may also be used in the lubrication solution.
