First Claim
Patent Images
1. A method for providing a protective, lubricious coating on a surface of a medical apparatus, the method comprising:
- applying a coating solution to a surface of the medical apparatus such that a protective, lubricious layer is formed upon the apparatus surface,wherein the coating solution comprises a protective compound and a slip additive and the formed layer contains the protective compound as a binder to maintain domains of the slip additive such that lubricating amounts of the slip additive are exposed to provide lubricity.

Abstract
A method for providing a medical apparatus with a protective, lubricious coating is described. The method comprises providing a coating solution which contains a protective compound such as a urethane, a slip additive such as a siloxane, and optionally, a crosslinking agent for the protective compound such as a polyfunctional aziridine, coating the solution onto a surface of a medical apparatus and allowing the coating to set. The resulting surface coating is lubricious, tough and flexible. The coating is well suited for use with materials used as components of balloon catheters.
