An anastomosis device may include a central region, and at least one projection connected to the distal end of the central region, where at least one projection is foldable in at least the proximal direction. An anastomosis device may include a central region, and an inner flange connected to the distal end of the central region, the inner flange deployable from a first position to an expanded position, where the inner flange includes at least one substantially triangular inner flange element. |
