This paper presents the 3D vessel model having a temperature responsive function for evaluation of thermal damage during surgery. The materials of model are polydimethylsiloxane(PDMS) and thermochromic dye which indicates irreversible color change according to temperature increase. Temperature increase of the materials can be measured from their color change. The accuracy of the temperature measurement is approximately from -3.5 / + 2.4 ℃ and the precision is ±3.1 ℃ in the range from 60 to 100 ℃. The vessel model is fabricated by dip coating on 3D wax model and lost wax method. However, acetone for removing wax prevents the temperature responsive function of the material. Thus, the surface of the model is coated with protective layer of polyvinyl alcohol(PVA). Finally, we succeeded in fabricating the renal artery model for catheter ablation.
