Recent advances in the design and fabrication of high-pressure medical balloons have enhanced their performance capabilities and broadened their use into new applications in the device industry. Developed in the late 1970s, high-pressure balloons have traditionally been used in angioplasty, a procedure that opens a blood vessel clogged by a buildup of fatty plaque. The balloon, tightly wrapped around a catheter shaft to minimize its profile, is inserted through the skin and into the narrowed section of the vessel. Inflating the balloon—typically with saline or a radiopaque solution forced through a syringe—exerts high pressure, which compresses the plaque against the wall of the vessel and allows the blood to flow normally.
