A patented coating eliminates the chance of an angioplasty balloon being punctured or damaged during stent delivery and post-stent dilation. It increases the coefficient of friction between stent and balloon surface so there is no movement or slippage. The coating can be produced from a variety of polymers. Balloons can be produced in a range of sizes, configurations, lengths, and burst pressures. Wall thickness is typically 5 to 50 µ. Balloons are available with 0.5 to 50-mm diameters and sizes from 2 to 12 mm.
