Abstract
An elongated insertion tube can be provided having a wall having one or multiple layers. A layer of a wall can include composite material having healing agent storage structures that store healing agent material and a catalyst dispersed within a polymer matrix. The layer can be formed so that when force is imparted to the layer, healing agent material stored within a storage structure reacts with a catalyst and polymerizes, to heal damage imparted to the layer.
