PROBLEM TO BE SOLVED: To provide a device and a method for producing a device effective for folding a balloon small on a catheter tube as anticipated during balloon deflation so that a balloon catheter can be easily taken out of the body of a patient. SOLUTION: The device for folding the balloon of the balloon catheter during balloon deflation is provided with a band and a plurality of elongated fingers attached to that band. This band is formed with a tub and a notch and the length of the band is equal to the diameter of the catheter tube. The band is folded into an annulus to interlock the tub with the notch. The annulus is attached to the catheter tube of the balloon catheter with the fingers extending over the balloon in a substantially same axial direction. In operation, the fingers are movable between an unstressed configuration, when the balloon is deflated, and a stressed configuration, when the balloon is inflated. In the stressed configuration, the fingers urge against the balloon and are biased toward the stressed configuration to return to the unstressed configuration. |
