位置を知ることが必要である。<< Prior Art >> In a balloon catheter used for treating or inspecting a diseased part generated in a living body lumen, it is necessary to accurately grasp the position of the balloon. For example, in the case of a balloon catheter used for expanding a stenotic portion of a living body lumen, the balloon portion is accurately reached to the stenotic portion, the balloon is inflated, a contrast agent is injected from the catheter tip, and the affected area is selectively selected. It is necessary to know the positions of both ends of the balloon when imaging the.

れている。FIG. 1 is an overall view of a balloon catheter according to an embodiment of the present invention. In the balloon catheter of the present invention, a side hole (2) is opened near the tip of the catheter tube (1), a balloon (3) is attached so as to wrap the side hole (2), and at the rear end of the catheter tube (1). Has a connector (7) for fitting a syringe or the like.

ン樹脂などが望ましい。As shown in FIG. 2, the balloon tube (3) fixed portion at the distal end of the catheter tube (1) has a side hole (2) formed in the side wall of the catheter tube (1) inside the balloon (3). A liquid for inflating the balloon (3) can be injected through the side hole (2) from the lumen of the tube (1). The material of the catheter tube (1) is preferably soft vinyl chloride resin, polyurethane resin or the like.

ーパーを付けなめらかに仕上げる。Next, a method for attaching the balloon (3) to the catheter tube (1) will be described. First, a cylindrical balloon (3) is passed through the catheter tube (1), and about half of the fixed portions at both ends of the balloon (3) are wound with a thread (4). As the material of the thread (4), it is preferable to use silk thread, nylon thread, or the like. Subsequently, an adhesive (5) containing a radiopaque substance is put between the end of the balloon (3) and the catheter tube (1) in the other half of the balloon fixing portion, and a thread (4) is wound on the adhesive. Further, from the top of this balloon thread winding part, adhesive (6)
Is applied to bond the thread (4), and the surface of the thread winding portion is tapered to finish smoothly.

確認ができる。The adhesives (5) and (6) used here are preferably polyurethane type or silicone rubber type, and the X-ray opaque substance contained therein is barium sulfate, bismuth oxide or the like. The amount of the X-ray opaque substance contained in the adhesives (5) and (6) is preferably 10 to 50% by weight.
~ 30wt% is desirable. If the amount of X-ray opaque substance in the adhesive is less than 10% by weight, sufficient contrast cannot be obtained, and if it is more than 50% by weight, it is difficult to sufficiently mix with a polyurethane or silicone rubber adhesive. , Workability remains a problem. The adhesive mixed in these mixing ratios is used for vacuum fixing and balloon fixing and tapering of the bobbin portion. As a result, X-ray opacity is imparted to both ends of the balloon (3), and the position of the balloon (3) can be confirmed under fluoroscopy when using the balloon catheter.
上記の範囲で放射線不透過物質を含んだ接着剤を用いる
