A new kind of coronary artery stent made of 316L stainless steel was designed and processed by using laser cutting and electrochemical polishing which was used to remove the sharp corner of the stent caused by the laser cutting.

In this paper,the processing techniques including output power,frequency,cutting speed,pulse width and assistant air pressure,which influence the quality of the coronary artery stent,have been studied with the fiber laser precision cutting system.

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.

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.

Construction of model on strut width variation of cardiovascular stent cut by laser;

Studies on adhesion of Ti and TiO_2 films on vascular stent;

This article is a review of 5 years of research into vascular stent reendothelialization research.

Experimental study of several intravascular stents with different materials;

The implantation of intravascular stents has become a new method to cure stenosis in arteries with its low injury and high efficiency.
