Abstract

The invention relates to a stent for angiostenosis. The stent is an arch-shaped flared balloon expandable stent; the front end of the stent is a large opening, and the rear end of the stent is a smallopening; the stent consists of a plurality of annular supporting members and connecting pieces; the plurality of annular supporting members are arrayed in the axial direction; adjacent annular supporting members are connected by the connecting pieces; the annular supporting members consist of a plurality of unit waves with the same shape; the interval between the unit waves of the annular supporting members is gradually reduced from the front end to the rear end of the stent; the unit waves of the annular supporting members are intensive. The invention also provides a matched dilated ballooncatheter. The stent has the advantages that the stent is specially designed for the angiostenosis and is in an arc-shaped flared shape. The dilated stent disclosed by the invention better accords withanatomical features of child angiostenosis treatment and obtains optimal treatment effects.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent applied to stenosis of blood vessel openings. Background technique [0002] According to global statistics, congenital heart disease (CHD) accounts for nearly one-third of major congenital malformations, and the prevalence of CHD is highest in Asia. In my country, the incidence of congenital heart disease accounts for about 8‰-12‰ of births, and it has become the leading cause of neonatal death. Among them, the proportion of subtypes of pulmonary artery outflow tract obstruction is higher. Therefore, pulmonary artery branch stenosis, pulmonary vessel restenosis after congenital heart disease surgery, and stent implantation treatment for constriction of the aorta have become one of the hotspots of clinical concern for congenital heart disease in recent years. [0003] Different from adult vascular stenosis, the vascular stenosis associated with congenital heart disease ...
