Abstract: A catheter such as an endotracheal tube is rendered resistant to laser beam impaction by coating the cuff and/or the tube with a laser-reflective compound which is preferably comprised of one to three parts of powdered aluminum to one part silicone rubber solution. The laser-reflective compound may be permanently bonded to the cuff and/or the tube by first dipping the cuff and/or the tube in a bath of the compound to form a smooth outer coating on the cuff and/or the tube and then baking the cuff and/or the tube to cure the coating. The laser-reflective coating serves to reflect the laser beam, thus making the catheter laser resistant while the smoothness of the coating aids in catheter insertion.
