The tubulose casting process of such as dip-coating can be used for forming base material by polymer solution, and these base materials can be used to manufacture the implantable apparatus of such as support.Polymeric substrate also has multilayer, and they have the intrinsic property of parent material, and extend enough to prevent brittle fracture.Time delay between such as core dipping time, the duration impregnated every time in the solution can be controlled and impregnated every time, or in drying between each dipping or hardening time and core immersion solution and/or the parameters of speed that are extracted from solution, to cause required mechanical property.Additional post processing can also be used to further enhance the intensity of base material or change its shape.
