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.

Human-like collagen(HLC) was firstly cross-linked with hyaluronic acid(HA) in different ratio by genipin for constructing tissue engineering blood vessel scaffolds.

Microstructure,element composite,mechanical properties,cytotoxicity grade,and biocompatibility of different vascular scaffold groups were studied by scanning electron microscope (SEM),X-ray photoelectron spectroscopy (XPS),tensile test,burst pressure experiment,cytotoxicity experiment,endothelial cells planted in blood vessel scaffolds and hypodermic embedding of mice.
