  1. Through experiment and analyzing the changes of the thickness, rigidity, tensile strength and the opening rate of the conduits caused by the different kinds of coating material, the thickness of the coating and the different braiding structures, we investigate the physical and mechanical, properties of the braided conduits. the results show : the chitosan is easy to form the film structure on the surface of the conduits increasing the conduits ' rigidity clearly ; the rigidity and opening rate of the braided structure with inserted reinforcing yarn are better than the others, this will prevent the conduits collapsing and distorting effectively in the practical uses, so we select conduits of this structure for animal experiment
