Abstract

An elastomeric back-up pad having a smooth laser-resistant coating thereon is provided for insertion between tissue layers incised during surgical procedures in which a laser is used to incise the tissue. The laser-resistant coating on the pad comprises a mixture of powdered metal which tends to reflect the laser beam and an elastomer which bonds the coating to the pad and imparts a smooth exterior surface to the coating thereby reducing the risk of tissue trauma as the pad is inserted between the tissue layers.
