发明名称 FOLDING SPRING FOR A CATHETER BALLOON
摘要 A device for folding a balloon of a balloon catheter during balloon deflation includes a band and a plurality of elongated fingers that are attached to the band. The band includes a midsection and a pair of overlaps with each overlap extending from the midsection to a respective end of the band. The band is folded into an annulus wherein the overlaps are juxtaposed and can be joined together by soldering, welding or adhesive bonding. 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 moveable between an unstressed configuration, when the balloon is deflated, and a stressed configuration, when the balloon is inflated. In a stressed configuration, the fingers urge against the balloon and are biased toward the stressed configuration to return to an unstressed configuration.< /SDOAB>
