We have proposed an adhesion method by using integrated low-level energy sources of heat, vibration and pressure. This adhesion method is expected to be applied to adhere biological tissue to the metal specimen such as stent-graft and blood inlet cannula of ventricular assist devices. Shear tensile tests on porcine aorta adhered to stainless steel were performed to determine the relationship between adhesive strength and adhesion conditions, such as pre heated temperature at heater tip, method for applying heat to biological tissue and stainless steel. The average adhesive strength was 0.148 MPa under the condition with pre heated temperature of 200 ℃, on adhesion time 120 seconds, on adhesion pressure of 2.5 MPa, in the heating from stainless steel. The adhesive performance was found to be improved by applying heat from metal in adhesion biological tissue to metal.
