title: [Expansion, deformation and bursting characteristics of commonly used balloon dilatation catheters. In vitro studies (1)].
abstract: We evaluated the characteristics of dilatation and deformation, as well as pressure requirements, bursting point, and type of bursting of the five most common balloon dilatation catheters. Polyvinyl chloride, polyethylene, and polyurethane-nylon balloons from 4 different manufacturers were examined in water-baths and an arrangement of tightly fitting teflon tubes. Defined balloon inflations were monitored and documented until balloon rupture occurred. Significant differences were found according to the different constructions and materials of the balloon catheters. Modern PVC showed a quality equal to PE material. Marked and clinically relevant differences of balloon compliance and behaviour in the water baths and within teflon tubes were demonstrated.
