To solve the problem of uneven strut widths of stents cut by laser, laser cutting procedure test was conducted, and the motion of the tube was analyzed.

Objective To explore the diagnostic value of CT perfusion imaging on cerebral ischemia and on evaluating cerebral hemodynamics changes of preoperative and postoperative artery stenting for intracranial and extracranial artery stenosis.

At present,there are many biomaterial for stent manufacture,the performance of the metal stent is more stable,it can provide the better support intensity.

In this article, it is indicated how to use software to realize the automatic counting of the support material used in chemical piping and the output of the material tables, so as to raise the efficiency of the piping support design.

Plastic deformation during intravascular stent expansion;

Methods The Chinese pigs after PTCA were implanted with the superficially modified intravascular stents.

Expansion uniformity is an important mechanic property of intravascular stent,which produce a critical effect on safety of the stent.
