| 摘要 |
The invention relates to a two-balloon catheter device for coronary angioplasty and its use, which finds application in medicine for the treatment of stenosis (constriction or narrowing) of the coronary blood vessels. The two-balloon catheter device consists of a first balloon, monolithically fit into a first carrying catheter with a proximal and a distal end, a dilatation guide situated in the first balloon and in the first carrying catheter longitudinally and extending beyond the proximal and distal ends of the first catheter, a second balloon monolithically fit into a second carrying catheter with a proximal and a distal end. By means of a dilatation syringe with a nozzle, air is fed under pressure into the two catheters and the respective balloons, where the first carrying catheter is situated in the second balloon and in the second carrying catheter longitudinally and coaxially. Where the first carrying catheter is a dilatation guide of the second balloon and of the second carrying catheter. The two balloons are capable of two-way movement jointly or separately along the coronary blood vessel through the respective stenoses.
