てバルーン２と造影リング３を作製している。The most important thing about this contrast ring 3 is that the contrast ring 3 expands following the expansion of the attached balloon 2, and that the contrast ring 3 expands when the balloon 2 is inflated.
can be confirmed with xg. That is, if the contrast ring 3 contains a large amount of contrast material, when the balloon 2 is inflated,
Although it can be clearly seen with X-rays, it is difficult to follow the balloon's expansion, whereas if it contains only a small amount of contrast material, it is possible to follow the balloon's expansion, but XIs Therefore, when the balloon 2 is inflated, it can be clearly confirmed with X-rays, and in addition, it can be expected to expand sufficiently to follow the expansion of the balloon. In this example, the balloon 2 and the contrast ring 3 are manufactured using silicone rubber having the following physical properties and prescription.

ｍ、内径６ｍのバルーン２を作製した。Using silicone rubber with hardness of 31, tensile strength of 75 kg/alt, tear strength of 24 kg/am, and elongation of 910%, it is pressed to a length of approximately 401+ and a thickness of approximately 0.5 m.
A balloon 2 having an inner diameter of 6 m and an inner diameter of 6 m was prepared.

グ３を作製した。On the other hand, the hardness is 26. Silicone rubber with a tensile strength of 85 kg/J, a tear strength of 38 kg/as, and an elongation of 1250% was used, and fine tungsten powder (
Add 150 parts to 100 parts of silicone rubber of the balloon) and 500 cs of silicone oil (2.5 parts to 100 parts of silicone rubber of the balloon), mix well, press in the same way, and cut. A contrast ring 3 having a width of 5I, a thickness of about 0.5 mm, and an outer diameter of 6IfaI was prepared.
そして、この造影リング３を接着剤（ＲＴＶシリコーン
ゴム）を用いて、第２図に示すようにバルーン２の内面
に固着して取り付けた。Then, this contrast ring 3 was fixedly attached to the inner surface of the balloon 2 using an adhesive (RTV silicone rubber) as shown in FIG. 2.

もよい。When attaching the contrast ring 3, an annular groove for the contrast ring set with a depth of about 0.511ta and a width of 5I is provided at the center of the inner bottle of the balloon mold without using the adhesive as described above. After setting the contrast ring 3 in this groove,
Pressed at low pressure using silicone rubber for Nokurune,
The contrast ring 3 and the balloon 2 may be integrally molded.

１の先端部に取り付けられる。The balloon 2 with the contrast ring 3 produced as described above is attached to the distal end of a two-lumen catheter 1 with an outer diameter of six strokes, as shown in FIG.

、このくびれがなくなり、むしろ好ましい。It goes without saying that the contrast ring 3 is not necessarily limited to an annularly connected ring, but may be cut at several points in the circumferential direction. With such a structure, when the balloon 2 is inflated, in the case of a single ring, the balloon 2 tends to become constricted at the ring portion, but this constriction is eliminated, which is rather preferable.

た。Using the catheter 1 described above, the catheter 1 is inserted through the patient's nose according to a predetermined procedure, and after positioning the balloon 2 in the intestine, for example, the balloon inflation inlet (see Fig. After inflating the balloon 2 by injecting 30 cc of sterile water (not shown), the contrast ring 3 was confirmed with X-rays, and it was clearly visible.

Using 250% silicone rubber, tungsten fine powder as a contrast material and silicone oil: 500c
It is produced by adding s, sufficiently kneading, and then pressing.

Further, the contrast ring as a contrast member is an example, and a non-ring-shaped one having an appropriate shape such as a rectangular or circular shape may be attached to all or part of the inner surface of the balloon.

り確かなものとなるという優れた効果がある。This invention is as described above, and the position and inflation state of the balloon can be confirmed with X-rays through the contrast member attached to the inner surface of the balloon or the balloon itself containing the contrast material, unlike the conventional method. Since the contrast medium (liquid) is not used unnecessarily, it is possible to avoid the conventional problem of the contrast medium clogging the pore lumen, resulting in high safety. In addition, the structure is simple, especially in the case of claim 1, since the contrast member is manufactured separately from the balloon, it can be attached to a ready-made balloon, and in the case of claim 3, the balloon itself has contrast properties, The overall shape of the inflated balloon can be confirmed with X-rays, which has the excellent effect of making the position and inflation state of the balloon more reliable.
