An applier for an anastomosis ring device. The applier has an elongate implement portion and a handle connected to the implement portion. The applier further includes a distal actuating member having catch means which, in a lock position, protrudes radially outward to engage a distal ring. The applier further includes a proximal actuating member adapted to engage a proximal ring, and an actuation mechanism to approximate the proximal and distal rings. The distal actuating member is rotatable about a longitudinal axis from its lock position to a release position thereby sliding along a deviating surface at the implement portion.
