A MATERIAL FOR USE IN MEDICAL DEVICES WITH A SELF-REPLENISHING ANTIMICROBIAL AND/OR LUBRICIOUS SURFACE

摘要

The material of this invention provides a continual supply of an antimicrobial agent and/or a lubricious agent to the surface thereof. A carrier may be used to facilitate the migration of the antimicrobial and/or lubricious agents to the surface of the material. These agents migrate to the surface as a result of the incompatibility, i.e. low miscibility and low solubility of the antimicrobial and/or lubricious agents and carrier, it one is used, with the base material that is used to form the medical device. In a preferred embodiment, the base material (1) is a silicone elastomer, the carrier (2) is siloxane oil and thus also acts as the lubricating agent oil and the antimicrobial agent (3) is chlorhexidine.
