The inflationary model of the universe provides solutions to many cosmological problems, such as the flatness and horizon problems and the origin of the CMB fluctuations. Topological defects are expected to have formed in the very early universe, leaving signatures observable in the CMB. It is also possible for such defects to have survived until today when they may be directly detected. We will discuss the problems of production and evolution of cosmic strings in the brane inflationary model. Since such strings can in fact be higher dimensional objects wrapping compact dimensions, their properties can be very different from those of Abelian Higgs strings. Experimental detection of these strings can offer a unique observational window in an energy range inaccessible by other means.
