Embodiments of the present invention provide medical devices for treating a target site within the body and associated methods for fabricating and delivering medical devices. According to one embodiment, a medical device includes a tubular structure having proximal and distal ends and a side wall extending therebetween. At least a portion of the side wall can have a corrugated surface. The side wall further includes at least one layer of a metallic fabric configured to be compressed and heat set to define the corrugated surface. The tubular structure may comprise an expanded shape, and may be configured to be constrained to a smaller diameter than the expanded shape for delivery within a catheter to a target site and to assume the expanded shape upon release from the catheter.
