Abstract

A surgical tool (10) for use in initial placement of a gastrostomy device in a patient includes an obturator (20), a cannula (14) and an outer flexible tubular member (16). A pointed end (38) of the obturator and an adjacent dilator (18) cooperate to incise a tract through the abdominal and stomach walls of the patient. The obturator is removed, leaving the cannula and outer tubular member in place. A
deformable section (44) of the flexible tubular member is expanded by movement of the cannula. The outwardly deformed section is then pulled up against the inner wall of the stomach wherein the thickness of the stomach and abdominal walls can be measured by use of visible scale indicia (48) carried on the external surface of the flexible tubular member. Subsequent to the noted measurement, a guide wire or pull wire (108) is passed through a lumen provided by the cannula. The guide wire is used for placing a gastrostomy device of suitable size in the incised tract.
