Description

Two-stage curved balloon ware {Angled Balloon}

The present invention relates to a balloon for a two-stage flexion vessel. More specifically, the present invention is a balloon for two-stage curved blood vessel including a central axis of the tubular structure for supplying fluid to the balloon portion including the front and rear balloons and the electric balloon so as to be bent according to the bending of the blood vessel It is about.

In general, coronary tissues with internal diameters are known as blood vessels, esophagus, intestines, bronchus, airways, biliary tract, urethra, etc., and these structures cause narrowing of the internal diameter by arteriosclerosis in blood vessels and cancer in other organs. . For example, in patients with angina pectoris, stenosis of blood vessels such as coronary arteries and peripheral blood vessels occurs due to cholesterol deposition, and the flow of blood is reduced, which may cause severe pain or sudden death. In the case of patients with esophageal cancer, biliary tract cancer, and the like, shortness of breath, food intake, and digestive disorders occur due to stenosis caused by cancer masses.

There are three known treatment methods for treating these symptoms: First, artificially connecting the narrowed blood vessels and coronary tissues through surgery as a bypass technique. In addition, there are problems such as accompanying fear. Second, a balloon catheter is inserted into the narrowed blood vessel and tubular tissue to fix the constricted area and then expand the constricted area through balloon expansion. This method is a problem of pain or fear. Although somewhat resolved, there is a problem that the incidence of restenosis exceeds 70%. Third, in order to improve the high restenosis rate, which is a problem of the method using the electric balloon ceramics, a mesh stent made of stainless steel and various metals is inserted into the constricted tubular tissue to the size of the original tubular tissue. By widening, it is a way to maintain the normal function of blood vessels and coronary tissue.

Among the above-mentioned methods, the method using a stent is known to be the most effective, but the method using an electric stent is required for balloon ceramics. The balloon ware carries the stent to the constricted blood vessels, expands the transported stent, and serves to fix the expanded stent. In the treatment of such stents, one of the problems to be solved is the problem of stents when curved blood vessels are constricted. In other words, when the curved portion of the blood vessel is narrowed, it is preferable to perform the stent in accordance with the curved portion, but it is impossible in reality. At present, the stent is flexibly manufactured to allow expansion and contraction naturally, and it can be bent to bend blood vessels, but since the inflatable ceramics that expand the stent inside the stent expand in a straight line, damage to the unstenled blood vessels can be caused. And often cause new vascular diseases. In order to solve this problem, various efforts have been made, but no special solution has been proposed.

Therefore, there is a constant need to develop a new method of stents for the treatment of stents on curved vessels without damaging non-stricted vessels.

The present inventors have diligently researched to develop a method for the treatment of a new stent for performing a stent on a curved blood vessel without damaging the unstenled blood vessel. As a result, the balloon portion of the conventional stent balloon balloon is separated from the shear balloon and the trailing balloon. When manufacturing a double-stage curved blood vessel balloon modified to have a balloon structure, and stents are applied to the curved blood vessel using an electric double-stage curved blood vessel balloon, the shear balloon and the rear-stage balloon have the angle of the existing vessel. By expanding while maintaining, it was confirmed that the stent can be treated at the constricted portion of the curved blood vessel, and in this case, it is possible to prevent damage of the unconstricted blood vessel, thereby completing the present invention.

After all, the main object of the present invention is to provide a two-stage curved blood vessel balloon having a two-stage balloon structure of the front and rear balloons.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail the operation and effect of the two-stage curved vascular balloon provided in the present invention.

The two-stage curved blood vessel balloon of the present invention, the balloon portion having a two-stage balloon structure of the front balloon (1) and the rear balloon (2), using the two-stage curved blood vessel balloon of the present invention to perform a stent to the curved blood vessel In this case, since the front balloon 1 and the rear end balloon 2 may expand at an angle according to the angle of the blood vessel, the stent may be performed without damaging the unconstricted blood vessel. That is, as shown in Figure 1, the two-stage curved blood vessel balloon of the present invention because the front balloon (1) and the rear balloon (2) is connected, it can be bent in compliance with the angle of the vessel around the connected portion. After the two-stage curved blood vessel balloon is bent in accordance with the angle of the inserted blood vessel, the fluid introduced through the central shaft 3 shown in FIG. 2 passes through the front fluid supply window 8 and the rear fluid supply window 9. It flows into the front-end balloon 1 and the rear-end balloon 2, and expands them (refer FIG. 5). Figure 5 is a schematic diagram showing the balloon in the state of being inflated in a curved state, the cone-shaped proximal end of the front balloon portion and the cone-shaped distal end of the rear end balloon is inflated, close to each other, as a result of the gap between the connection portion of the shear balloon and the rear end balloon This fills up. At this time, the fluid used is not particularly limited, but it is preferable to use a mixture of physiological saline and contrast agents.

On the other hand, after using the two-stage curved blood vessel balloon of the present invention to perform a stent to the curved blood vessel, the two-stage curved blood vessels used electricity can be used as a high pressure adjustive balloon (high pressure adjustive ballon).

In general, after the stent is expanded in the blood vessel, the operation is performed to bury the stent in the constricted blood vessel wall so that the stent is not separated by blood pressure, this operation is performed by using a high pressure compliant balloon. That is, by inserting a balloon of a shorter length than the surgical stent in the stent site, and by applying a high pressure to expand the balloon, the stent is buried in the blood vessel wall by the expansion pressure of the balloon. However, in order to insert and inflate the stent, a balloon that is longer than the length of the stent is used. Therefore, a new balloon is required for electrical work, which is not economical.

The two-stage curved blood vessel balloon of the present invention can be used not only for curved blood vessels, but also for straight blood vessels. If the stent is operated with the two-stage curved blood vessel balloon of the present invention, the stent is not used without using a new balloon. May be on blood vessel walls. That is, as shown in Figure 2, the two-stage curved blood vessel balloon of the present invention is provided with a fluid supply pipe 10 and the fluid supply window 11 that can only expand the rear end balloon (2), the electric fluid supply pipe (10) In the case of inflating only the rear end balloon 2 by using the fluid supply window 11 and the inflatable balloon, it is possible to form a balloon of a length shorter than the length of the original balloon, so that the blood vessel wall is used as a high-pressure compliant balloon. Since the stent can be buried, and does not require a separate high pressure compliant balloon, it is possible to economically perform the stent.

Summarizing the above, the method for stent treatment using the two-stage curved vessel of the present invention will be described as follows: First, confirm that the narrowed portion of the patient's blood vessels is the curved portion, and the guideline is narrowed. After the insertion, the end of the lead wire is inserted into the distal opening of the guide tube (7) of the two-stage curved blood vessel balloon stent equipped with stents, and the two-stage curved blood vessel inflatable stent is moved along the guide line. After that, the stent-mounted double-curve balloon balloon is inserted to fit the angle of the constricted portion of the curved blood vessel based on the radiolabel 4, 5, 6. Then, the fluid is injected into the front end balloon and the rear end balloon of the balloon pottery through the front fluid supply window 8 and the rear end fluid supply window 9 provided on the central shaft 3, and the curved angle of the constricted vessel part The balloon is expanded while maintaining an angle similar to that of the balloon, and the stent is expanded by the expansion of the balloon. Subsequently, the fluid is sucked from the front balloon and the rear balloon, the balloon is reduced, and then the fluid is injected and expanded only to the rear balloon 2 through the fluid supply pipe 10 and the fluid supply window 11 to expand the rear balloon. Use 2) as a high-pressure compliant balloon ceramic to bury the stent on the vessel wall.

As described above and proved in detail above, the present invention is a two-stage curved blood vessel comprising a central axis of the tubular structure for supplying fluid to the balloon portion including the front and rear balloons and the electric balloon so that it can be bent according to the bending of the blood vessel Provide a dragon ball. When the stent is performed on the constricted portion of the curved blood vessel using the two-stage curved blood vessel balloon of the present invention, the stent can be performed without damaging the unconstricted vessel portion, and the high-pressure compliant balloon after the stent treatment is performed. Using it as a ceramic, the stent can be planted in the vessel wall without the use of an additional stent, so that the procedure can be performed safely and economically.
