Dr. Smith likes to achieve pneumoperitoneum through a small incision made in the umbilicus with an #11 blade. The _____ is inserted and the distal hub is filled with NaCl using a 10 cc slip tip syringe. The small ball in the distal hub floats until the peritoneum is entered. This device and technique allows Dr. Smith to be sure of the proper placement prior to starting the insufflation with the gas to achieve pneumoperitoneum because the negative pressure of the abdominal cavity will draw the NaCl in and the ball drops.
