A method of making and recycling a golf ball is disclosed. An opening in one plate communicates with the measuring vacuum chamber and has a sealed connection for joining to medium to be measured. A mechanical link is rotatably connected to the leg so that movement of the mechanical link applies rotational force to the leg to cause the leg to rotate about the axis. In one embodiment, the outer woven sleeve is configured into a predetermined shape through manipulation of the catheter and used to maintain the inflated balloon within that predetermined configuration.
