Some patterns comprise radially expandable cylindrical rings that are longitudinally aligned, each ring comprising diamond-shaped elements, each formed by four linear bar arms. The patterns con also comprise a cross-like element comprising four linear bar arms interconnected within the diamond-shaped elements, and at least one link between adjacent rings. In other patterns, the rings comprise peaks and valleys formed by linear bar arms. wherein pairs of rings are configured such that the peaks of one pair are connected to the valleys of the other pair at apices of the peaks and valleys to form diamond shaped regions. In yet other patterns, there are two v-shaped elements formed by two short bar arms within the diamond-shaped elements, and a connecting bar arm connecting the two v-shaped elements.
