Vinyl chloride tube has been widely used as a material of circuit for the cardiopulmonary bypass and assisted circulation. However the antithrombogenesis of the vinyl chloride tube is not sufficient enough. The Avcothane ® coating on the surface of vinyl chloride tube was performed in order to imporve the antithrombogenesis of it. Pilot experiment showed the problem of Avcothane coating, that is lack of durability. Six kind of Avcothane ® coating techniques were applied to improve it's durability, and in vitro test was performed. This test showed that the durability of Avcothane ® coating can be slightly improved by using the glue, for example mixed solution of Avcothane ® and vinyl chloride.
