Which statement about non-compliant balloons is true?

• A. Stiffer/less flexible
• B. They are more flexible than compliant balloons
• C. They increase in diameter with ATM above nominal
• D. They rupture easily at nominal pressure

Answer: (A)

Non-compliant balloons are designed to be stiff and inflexible, so their diameter changes very little as you increase inflation pressure. This makes them ideal for precise lesion dilation and stent sizing because once you reach the desired diameter, additional pressure doesn’t significantly enlarge the balloon. They also have a high rated burst pressure, allowing inflation to higher pressures when needed without causing overexpansion. In other words, they resist expansion with increasing pressure, unlike compliant balloons which expand more with pressure.
