Abstract
Abstract A laser resistant endotracheal tube having a laser resistant layer surrounding the tube for at least a portion of the tube length. The laser resistant layer has a plurality of surface irregularities that are spaced from one another in a plurality of directions and which reflectively scatter laser energy. The laser resistant layer can be applied as an adhesive backed tape which has adhesive on only a portion of the width so that when the tape is spirally wrapped around the tube, the adhesive substantially avoids contact with previously wrapped tape. The tube can be provided with an inflatable cuff that is protected from degradation by an adjacent protective collar and the collar and a portion of the laser resistant layer can be covered with a laser resistant collar. The laser resistant layer can be covered by a cut resistant textile. A laser resistant tape, material and article are also disclosed.
