Balloon catheters have a wide range of diagnostic and therapeutic applications such as expanding blocked vessels and stent placement.
What are the types of balloons?
Non-compliant (high-pressure) balloons are commonly made of polyester or nylon. These balloons are used for applications in which the balloon needs to expand to a specific diameter and exert high pressure to open a blockage or to dilate the vessel.
Semi-compliant (mid-pressure) balloons are commonly made of Pebax or higher durometer polyurethanes. These balloons are used in applications that require mid-high pressures but need more compliance than a non-compliant balloon and more flexibility to ease delivery.
Compliant (elastomeric) balloons are typically made of polyurethane or silicone. These balloon are inflated by volume instead of pressure. They may be inflated from 100% - 800%. They are mostly used in applications that require the balloon to fully conform to or occlude the anatomy.
