This research aims to study the effects of experimental design parameters such as the number of wires, the length and braiding angle of stent on mechanical properties of braiding stentriever made from shape memory alloy. Self-expanding stents or stentriever were fabricated by braiding a number of wires together by braiding machine, followed by heat-treatment for shape setting. Superelastic NiTi shape memory alloy wires with diameters of 0.08mm were used while the number of wires was selected to be 12, 24 and 36, respectively. Braiding angle was designed to be 52oñ2o and 38oñ2o. Diameter of stentriever was set to be 4 mm. On the other hand, this design is focused on stent using in 3 mm to 4 mm intracranial vessel diameter stent, radial resistive test, radial expansion test and three-point bending test under temperature at 37o are carried out. The result shows that the maximum radial resistive force, maximum radial expansion force and maximum bending force which are equaled to 50 mN/mm, 37 mN/mm and 0.423 N, respectively can be confirmed in stent with 36 wires
