Problems solved by technology

However, the diameter of balloons using materials with higher elasticity (such as latex or silicone) can be made arbitrarily large, resulting in the problem that instruments or devices are required to accurately control the deployment of the inflatable balloon. diameter
Therefore, the balloon moves freely, so there is a problem that extremely high skill and attention are required to place the balloon at a predetermined position

Embodiment Construction

[0041] The catheter balloon 10 , the catheter 100 and the method for manufacturing the catheter balloon 10 according to an embodiment will be described in detail below with reference to the accompanying drawings. Figure 1 shows a schematic view of a partially deployed catheter balloon according to the invention. Figure 1B is a schematic view showing a state in which the balloon portion is separated from the strip portion. In this specification, the term "deployment" means that the balloon expands only by an increase in its internal pressure, and does not mean that the balloon itself is substantially inflated to inflate. The term "expanded" means that the strip is partially expanded to produce a larger diameter.

[0042] As shown in FIG. 1, the catheter balloon 10 according to the present embodiment includes a balloon portion 20 and a strip portion 30, the balloon portion 20 is cylindrical in shape, and is made of a non-expandable material or a low-expansion material; The st...

Abstract

[Problem] To provide a catheter balloon which, when treating calcific aortic stenosis, rheumatic and congenital aortic stenosis, etc., facilitates control of the expanded outer diameter of the stretchable balloon, enables effectively prevention of balloon migration, and can easily be fixed in a prescribed position. [Solution] This catheter balloon (10) is provided with a cylindrical balloon unit (20) formed from a non-stretch material or a low-stretch material, and a band unit (30) manufactured from a material consisting of a stretchable elastic body. The band unit (30) has a diameter shorter than the expanded diameter of the balloon unit (20) in a state in which no expanding force is being applied, and is wound around the middle part of the balloon unit (20).

Description

technical field [0001] The invention relates to a catheter balloon, a catheter and a method for manufacturing the catheter balloon. Background technique [0002] The etiology of aortic stenosis is, for example, acquired calcification or rheumatic aortic stenosis and congenital aortic stenosis. For example, in calcific aortic valve stenosis, as the lesion progresses, calcification of the valve leaflets develops, and the valve leaflets gradually harden. As a result, the range of motion of the valve leaflets is progressively restricted, leading to cardiac insufficiency. For this reason, in severe cases of valve leaflet stenosis, the stenosis must be treated surgically. [0003] For the treatment of this disease, balloon valvuloplasty is proposed as a less invasive procedure for expanding narrowed valves such as calcified aortic stenosis, or rheumatic aortic stenosis and congenital aortic stenosis. The current conventional procedure for the treatment of calcified aortic steno...
