Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention will be further described by specific embodiment:

[0038] See figure 1 , figure 2 , image 3 , Figure 4 , a non-implantable high-strength vasodilator, including a balloon catheter and its constraining stent, the balloon catheter is not shown, and the constraining stent includes a tubular structure for covering the outside of the balloon catheter 1 And the fixing part 2 connected to the two ends of the main body part 1 is used to fix the balloon catheter. The constraining stent is used to follow the expansion or contraction of the balloon catheter and restrain the maximum expansion volume of the balloon catheter. The balloon catheter and the constraining stent each have a function In a compressed form for placement in a blood vessel and an expanded form for resisting expansion in a blood vessel, the maximum diameter of the constrained stent in the expanded form is smaller than the maximum diamete...

Abstract

A constraining stent for a non-implantable balloon catheter, comprising a main body part in a tubular structure for covering the outside of the balloon catheter and fixing parts connected to both ends of the main body part for fixedly connecting the balloon catheter, The constraining stent is used to follow the expansion or contraction of the balloon catheter and inhibit the maximum expansion volume of the balloon catheter; a non-implantable blood vessel expansion device includes a balloon catheter, and also includes the aforementioned constraining stent, the balloon catheter Each of the constrained stents has a compressed form for placement in a blood vessel and an expanded form for resisting expansion in a blood vessel, and the maximum diameter of the constrained stent in the expanded form is smaller than that of the balloon catheter in the expanded form. The maximum diameter. The invention has simple structure and convenient use, greatly improves the therapeutic effect, and reduces the damage to blood vessels and the occurrence probability of complications.

Description

technical field [0001] The invention relates to the technical field of angioplasty surgical instruments, in particular to a high-strength constrained stent of a non-implantable balloon catheter and a blood vessel expansion device using the constrained stent. Background technique [0002] For cardiovascular disease, balloon angioplasty is one of the most commonly used treatments. Traditional balloon catheters are made into inflated cylindrical balloons with different diameters and lengths according to the size of the patient's blood vessels and the length of the lesion. The working principle is: use the delivery system to place a balloon dilation catheter on At the lesion, after the balloon is inflated, the blood vessel is expanded to realize the expansion of the lumen. [0003] Traditional balloon angioplasty is often accompanied by damage to blood vessels. For example, the diameter of the proximal and distal ends of the balloon is greater than the diameter of the middle of...
