Patterns for polymeric radially expandable implantable medical devices
such as stents for implantation into a bodily lumen are disclosed. 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.
