Embodiment 1

[0058] Such as figure 1 As shown, the fully-developed cohesive vessel stenosis dilatation balloon in this embodiment consists of a balloon body 100 with an outer diameter of 8 mm and a length of 60 mm, and three expansion and cutting structures 200 arranged longitudinally along the outer surface of the balloon body. Such as image 3 As shown, the expansion cutting structure 200 is composed of an outer cutting wire (wire winding) 211 and a developing spring 212. The cross section of the outer cutting wire 211 is an isosceles triangle with a triangular height of 0.5mm and a width of 0.8mm, and a length of 56mm. It is made of nickel-titanium wire with a diameter of 0.05mm, and the pitch is 0.08mm, which has excellent material properties and appearance structure; the cross-section of the developing spring 212 is circular with an outer diameter of 0.3mm, and is made of platinum-iridium alloy of 0.03mm , increasing the developing effect for the balloon and providing more structural...

Embodiment 2

[0061] Such asfigure 1 As shown, the fully-developed cohesive vascular stenosis dilation balloon in this embodiment is composed of a balloon body 100 with an outer diameter of 5 mm and a length of 100 mm and five expansion and cutting structures 200 arranged longitudinally along the outer surface of the balloon body. The cross-section is as follows: figure 2 . Such as Figure 4 As shown, the expansion cutting structure is composed of an outer cutting wire (pipe cutting) 221, an inner support tube 222 and an inner developing wire 223. The outer cutting wire 221 is a triangular top with an included angle of 40°, a height of 0.3 mm, and a length of 80 mm. The 0.04mm stainless steel 304V tube is cut, and the cut tube has a hollow structure to make it have good flexibility; the inner support tube 222 is a circular silicone tube with an outer diameter of 0.18 mm, an inner diameter of 0.05 mm, and a length of 85 mm. More structural support further improves the expansion and cutting...

Embodiment 3

[0064] Such as figure 1 As shown, the fully developed cohesive vascular stenosis dilatation balloon is fixed on the balloon body 100 with an outer diameter of 4 mm and a length of 80 mm by means of three expansion and cutting structures 200 through UV curing glue, as shown in Figure 9 As shown, after the two ends of the expanded cutting structure 200 are solidified, there is a buffer bevel with an angle of 25°, which prevents stress concentration during use and effectively improves the passing performance of the product. Such as Figure 4 The expansion cutting structure is composed of an outer cutting wire 221, an inner support tube 222 and an inner developing wire 223. The outer cutting wire (pipe cutting) 221 is an equilateral triangle with a height of 0.4mm and a length of 70mm, and is cut from a stainless steel 316 pipe with a wall thickness of 0.05mm. It has excellent material properties and appearance structure; the inner support tube 222 is triangular, and the outer d...

Abstract

The invention provides a full-developing force-gathering vascular stenosis dilating balloon. The balloon comprises a balloon body, wherein an expansion cutting structure is longitudinally arranged along the outer surface of the balloon body, and comprises a hollow cutting wire and a developing support structure arranged in the cutting wire; the cutting wire is fixed on the outer surface of the balloon body; and two ends of the developing support structure are fixed to the two ends of the balloon body respectively. Compared with the prior art, the balloon provided by the invention has the advantages that the hollow cutting wire and the developing support structure arranged in the cutting wire form the expanding cutting structure, so that the whole cutting part of the dilating balloon can bedeveloped under X-ray, the cutting part can be positioned more accurately, and besides, effective support can be provided for the cutting wire; and therefore, the flexibility and the trafficability of the balloon can be considered, and the dilatation cutting effect is further improved.

Description

technical field [0001] The invention belongs to the technical field of balloons, and in particular relates to a full-developing and cohesive blood vessel stenosis dilation balloon. Background technique [0002] Interventional medicine is guided by imaging medicine (X-ray, ultrasound, CT), through percutaneous puncture or through the original pores of the human body, inserting a special catheter or instrument into the lesion for imaging, diagnosis and treatment, because of its small trauma The advantages of less complications and wide application range (applicable to cardiovascular and cerebrovascular, peripheral vascular tumors or non-vascular fields, etc.) have become the third major clinical treatment method. [0003] Ordinary vascular stenosis dilation balloon, due to the compression and rupture of plaque and elastic expansion of blood vessels during expansion, the elastic recoil that is prone to occur is likely to cause restenosis. At present, dilatation balloons with m...
