    Mechanical testing methods were developed by us using the pulsatile internal pressure through-flow system. The methods were applied to estimate the permeability and fatigue strength of a vascular substitute, the mechanical behaviour of anastomosed site between vascular substitute and blood vessel, and the mechanical behaviour of the blood vessel itself. A testing method is also proposed for puncturing a vascular substitute which is used as blood access for hemodialysis. The mechanical behaviour of punctured vascular substitute and the puncturing technique itself are investigated. The fatigue-creep testing method of cellophane membrane is also reported to estimate the durability of cellophane membrane by using the circulating pulsatile internal pressure throughflow system. The mechanical testing method for visco-elastic characteristic of biomaterials is discussed.
