摘要： Coated medical devices include coated catheters. For example, a coated catheter can include a catheter tube of a tubular substrate and a coating thereover. The tubular substrate can be of a first polymeric material transparent to electromagnetic radiation in a range of visible light. The coating can be of a second polymeric material anchored to the tubular substrate by chain ends of the second polymeric material impregnated in the first polymeric material by way of a spent visible-light photoinitiator. Methods of coating can include methods of coating medical devices such as the coated catheter. For example, a method of coating can include irradiating a tubular substrate impregnated with a visible-light photoinitiator with the foregoing electromagnetic radiation while the tubular substrate is disposed in an aqueous solution of a monomer, thereby initiating a radical polymerization of the monomer and coating the tubular substrate with the coating of the second polymer material.
