An anastomotic ring applier system (30) for deploying a first compression ring (36) and a second compression ring (39) comprises an anastomotic appli er (32) with a second ring carrier (38) adapted to hold the second compressi on ring (39), a ring approximation device (37) with a first portion (42) con nectable to an external first ring carrier device (31) which supports the fi rst compression ring (36) and a second portion (43) connected to the second ring carrier device (38), wherein the first portion (42) and the second port ion (43) are connected to one another by a piston-cylinder thrust unit (66). A fluid pump device is connected to a pressure chamber (67) of the piston-c ylinder thrust unit (66) so that operation of the fluid pump raises the flui d pressure inside the pressure chamber (67) and causes the first and second portions (42, 43) to translate to one another to approximate and interconnec t the compression rings (36, 39).
