For the estimation of elastic parameters for a beam model of embolization coil, this paper performs the computational simulations of tensile/compress and bending tests of the coil. The coil configuration is constructed based on the observation results by the electron microscope. The load-displacement relationship for respective mechanical tests are investigated by means of the finite element method with consideration for the contacts between coil wires itself. The tensile stiffness of the coil is in excellent agreement with the theoretical solution, whereas the compressive and bending stiffness of the coil is relatively hard due to the contacts between the coil wires.
