ABSTRACT:
A shield from a laser beam has an upper material which disperses the laser beam into a larger cross sectional area, and a lower material which reflects the dispersed laser beam back through the upper material. The upper material may be a woven fiberglass sheet and the lower material may be a sheet made of woven metallic wires. The shield may be made from cylindrical fiberglass and metallic fabric as a shield for an endotracheal tube for use during laser surgery of a patient`s throat region. The materials may be made in sheets to form protective drapes for protection of equipment from a laser beam during laser surgery. An umbrella having a reflective surface that unfolds under pressure from a balloon used to secure an endotracheal tube in a patient's throat protects the balloon from the laser beam during laser surgery.
