Abstract:
Objective To improve the biocompatibility of the metallic stent used for interventional treatment. Methods Inner coatings, outer coatings and micro-porous coatings were made using the solution-injection method, and salt crystallite with demanded size was added in order to develop micro-porous coatings. Results The optical concentrations of polyurethane solution and of salt crystallite (for micro-porous coatings) were obtained, and the corresponding processes were developed. Conclusion The poly-coated stent retains its elasticity, and it become very convenient to develop stents carrying drugs. Its effects on animals ard under test.
