Abstract: A catheter-disinfecting system can include, in some embodiments, an introducer sheath and a germicidal irradiation means for irradiating a catheter tube of a catheter with germicidal radiation. The introducer sheath can include a sheath body configured to be percutaneously inserted into an insertion site of a patient. The germicidal irradiation means can be configured for irradiating the catheter tube as the catheter tube is inserted into a lumen of the introducer sheath, thereby disinfecting the catheter tube immediately before insertion into the insertion site. A method of disinfecting a catheter such as the foregoing catheter can include inserting the catheter tube into the introducer sheath while the introducer sheath, itself, is percutaneously inserted into the insertion site of the patient; and irradiating the catheter tube with the germicidal radiation while inserting the catheter tube into the introducer sheath.

Abstract: 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.
