An apparatus for anastomosis of tubular structures includes two annular bodies. Each annular body has a first side, a second side, a central axis extending between the first and second sides, an inner wall defining a passageway that is open to the first and second sides for passing a tubular structure therethrough, and a plurality of spikes each extending from a base connected to the second side of the annular body to a pointed free end configured to pierce the tubular structure. The spikes are angled relative to the central axis such that for each of the spikes, the free end is positioned farther from the central axis in a radial direction than the base is to the central axis.
