    • A method of manufacturing angiographic catheters comprises providing a length of elastomeric tube of a predetermined outer diameter and braiding multiple strands of wire wrapping about its exterior. A bonding agent is applied to the wire wrapping in circumferentially extending bands to bond the strands to each other. Thereafter, the wire wrapping is ground away at predetermined spaced locations along the length of the elastomeric tube to provide a series of wire wrapped sections joined by non-wrapped sections with each of the wire wrapped sections having at least the ends thereof enclosed by at least portions of the circumferentially extending bands of bonding agent. An elastomer layer is located over both the wire wrapped sections and the non-wrapped sections throughout the length thereof. Subsequently, the coated length is severed into pieces with the pieces each constituting a wire wrapped section that forms a catheter body and a non-wrapped section joined to at least one end thereof to constitute a flexible catheter tip.
    • 一种制造血管造影导管的方法包括提供一定长度的预定外径的弹性体管,并编织围绕其外部的多条线缠绕。 将粘合剂施加到沿圆周延伸的带缠绕的线缠绕以将线股彼此结合。 此后,沿着弹性体管的长度将线缠绕在预定间隔的位置处被研磨,以提供由非包裹部分连接的一系列线缠绕部分,其中每个线缠绕部分至少具有至少封闭的端部 接合剂的周向延伸带的部分。 弹性体层位于两个线包裹部分和整个长度的非包裹部分之间。 随后,涂覆的长度被切割成块,其中各个构成线形缠绕部分,其形成导管主体和与其至少一个端部连接的未包裹部分以构成柔性导管末端。

    • The polyhedral body of aluminum such as a watch case obtained by the inventive method is colored in two different colors on different polyhedral faces demarcated by the ridgeline therebetween with remarkable decisiveness not obtained in the prior art methods. The inventive method utilizes anodization and coloring by dyeing in two steps. A part of the polyhedral faces anodized and colored in a dark color in the first step is ground to expose the bare surface of aluminum, which is then activated by dipping in an aqueous acid solution and again anodized by applying an unconventionally high voltage in an electrolyte bath of a specific composition followed by coloring in a light color decoratively distinguishable from the dark color imparted in the first step coloring. By virtue of the activation treatment of the bare aluminum surface and the unusual conditions in the second anodization, the demarcation between the differently colored polyhedral faces is very decisive and beautiful and the oxide films on both sides of the ridgeline have excellent adhesion and high anti-corrosion resistance.
    • 通过本发明方法获得的诸如手表壳体的铝多面体体在由它们之间的棱线划分的不同多面体面上以两种不同的颜色着色,其在现有技术方法中未获得显着的决定性。 本发明的方法通过两步染色利用阳极氧化和着色。 在第一步骤中阳极氧化和着色为深色的多面体表面的一部分被研磨以暴露铝的裸露表面,然后将铝浸入酸性水溶液中并通过在电解质中施加非常规高压再次阳极氧化 浴的特定组合物,然后以与第一步着色中赋予的深色装饰地区别的浅色着色。 由于裸铝表面的激活处理和第二次阳极氧化处理中的异常情况,不同颜色的多面体面之间的分界是非常决定性和美观的,并且脊线两侧的氧化膜具有优异的附着力和高抗蚀性, 耐腐蚀性能。
