A self-expanding stent is disclosed, the self-expanding stent having a collapsed configuration and an expanded configuration. The self-expanding stent has three stent subunits, each including one or more longitudinally-oriented diamonds and one or more axially-oriented diamonds. The subunits are coupled together at a pivot joint. The longitudinally-oriented diamonds are configured to substantially hold their shape in both the expanded configuration of the stent and the collapsed configuration of the stent. The axially-oriented diamonds are configured to expand from the collapsed configuration to the expanded configuration. Expansion of the axially-oriented diamonds creates angulation between the stent subunits at the pivot joint. Thus, the stent can be inserted into a target location through a tubular catheter, once the stent is no longer constrained by the catheter, it will expand to an angled configuration.
