An instrumentation for performing an endoluminal or transluminal anastomosis, comprises an anastomotic ring device including a proximal ring (5) having two guide wire seats (22) adapted to slidably receive two guide wires (1, 2) and a distal ring (6) having two guide wire seats (25) adapted to slidably receive the two guide wires (1, 2), the proximal ring 5 and the distal ring 6 being snap-connectable to each other, a surgical probe (7) comprising an elongate insertion shaft (30) and a probe head (32) adapted to be endoluminally advanced to a proximal tissue portion (3), the insertion shaft (30) defining guide wire canals (8, 9) extending into two guide wire exit openings (31) defined in the probe head (32) and adapted to deliver the distal ends (1'', 2'') of said guide wires (1, 2) to said proximal tissue portion (3). The distance between the two guide wire exit openings (31) of the probe (7) is substantially equal to the distance between the two guide wire seats (22) of the proximal ring (5) and to the distance between the two guide wire seats (25) of the distal ring (6). |
