Guidewire through blood vessels for medical treatment of cerebral aneurysm used for minimally invasive treatment. Operator observes a position from the outside of body using X-rays imaging method at this time. Therefore, high skill is required when operator insert guidewire in a complicated blood vessel. It is necessary to know the deformation behavior of the guidewire. Guidewire and vessel were modeled with cylindrical segment and rotary spring. The guidewire was pushed in the bend blood vessel. Then the root of guidewire was rotated at a curved part. Following performance and torque transmissibility were evaluated. Following performance of guidewire tip was good. About torsion operation, contact forces distributed nonuniformly, movement of tip was different from operation at hand.
