Strangulation of the artery of human body such as coronary blood vessel and peripheral artery is used in order re-to be understood the balloon catheter

摘要

An inflatable catheter for dilating stenoses in body channels, in particular coronary vessels and peripheral arterial vessels, comprises a microwave antenna (9) located inside the inflatable part of the catheter and connected by a coaxial cable (8) to a microwave generator. The action of the microwaves on a dilatation fluid which absorbs microwaves and/or on a metallic coating on the inflatable part of the catheter heats the inflatable catheter and subjects the wall of the vessel to a thermal after-treatment which prevents stenosis from reforming.
