A kind of cardiovascular arterial bracket
Technical field
The present invention relates to a kind of cardiovascular arterial bracket, belongs to cardiovascular technical field.
Background technology
At present, coronary artery disease is modal disease in cardiovascular disease, be also mortality rate and sickness rate higher
Disease, its main cause is the angiostenosis that atherosclerosis causes.Treatment coronary artery disease most common method is profit
Angiostenosis is opened with sacculus, the most permanent placement metal supports, the most well-known support.But stent endoprosthesis
The hyperplasia of rear inner membrance can cause the generation of restenosis, and the incidence rate of simple bare bracket restenosis is up to 10-30%, therefore crown
Arterial bracket inserts the most important thing that postoperative restenosis is always in Coronary Artery Disease Intervention Treatment research, is wherein coated with intracoronary stent
The research of layer is especially prominent.
