Catheter baloons come is various shapes and sizes. They are one of the basic tool for many medical procedure, like angioplasty. Baloons are manufactured from  polymer tubes with original wall thickness of 0.12mm to 0.5mm. Single wall thickness of the balloon, radially expanded in the mold during manufacturing, is 0.012 to 0.050mm.  The wall thickness has certain profile along the length of the baloon. This ensures the correct distribution of pressure.For example, angioplasty balloon has thinner wall in the center to have increased pressure in that area.  The thickness of the baloon wall needs to be measured  at different points: MProbe 40 MSP system makes it easy. The measurements are non-contact and are  done in a small spot – 0.040 to 0.008mm – depending of the diameter of the balloon. Thickness  measurement of the  baloons in inflated state  gives the best contrast. But thickness measurement of deflated balloon is also possible. Measurement results are precise and instant.
