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.

Abstract: A ring-supported lift crane is provided with a counterweight handling system to facilitate repositioning of the crane. The ring-supported crane includes a ring, a crane upper works and a crane lower works, a boom supported on rollers on the ring and a counterweight assembly also supported on rollers on the ring. The counterweight assembly preferably includes a counterweight carrier on which at least one stack of counterweight boxes or units are placed. A counterweight holder is interposed between the at least one stack of counterweight units and the counterweight carrier with a friction reduction device, such as rollers or slider pads, interposed between the counterweight holder and the counterweight carrier. When the ring-supported crane is to be repositioned for a second lift at a construction site, the counterweight holder with the stack of counterweight units is moved off of the counterweight carrier onto a separate counterweight support member, which may be mobile or stationary. This speeds up the relocation process, as the counterweight units do not have to be individually unstacked before the ring and crane can be moved.
