    Abstract: An apparatus and method for nonextrusion manufacturing of catheters that can be used to produce catheters having a simple or complex configuration. A polymer material in a particulate preform is applied in a layer over an outer surface of a core member. By applying the polymer material in a particulate preform, a composition of the polymer material can be varied continuously as it is being applied to provide a variable hardness over the length of the catheter. A fibrous reinforcement can be used having a constant or variable pitch and a constant or variable number of fibers and fiber types. Sensors can be easily placed in a wall of the catheter as the catheter is being fabricated, thereby allowing more sensors to be used without placing conductors in the lumen of the catheter. Deflection passages can be provided in a wall of the catheter for inserting a wire to deflect the catheter. The polymer material can be heated into molten form as it is being applied, or the core mandrel or liner can be heated to cause the polymer material to consolidate upon impact. A mandrel in the preferred embodiment is rotated about its longitudinal axis while a spray head and filament winding head traverse the length of the mandrel and apply polymer material and filament, respectively. Other arrangements can also be used, including a spray head and filament winding head that rotate about a continuous core mandrel, and a fluidized bed or other container into which a heated core mandrel is immersed. A plurality of mandrels can be placed side-by-side to form a multiple lumen tubing.

    Abstract translation: 可以用于制造具有简单或复杂构型的导管的导管非渗出制造的装置和方法。 颗粒状预制件中的聚合物材料被涂覆在芯构件的外表面上。 通过将聚合物材料应用于微粒预制件中，聚合物材料的组合物可随着其应用而连续变化，以在导管的长度上提供可变的硬度。 可以使用具有恒定或可变节距以及恒定或可变数量的纤维和纤维类型的纤维增强材料。 当制造导管时，传感器可以容易地放置在导管的壁中，从而允许使用更多的传感器而不将导体放置在导管的内腔中。 可以在导管的壁中设置偏转通道，用于插入导线以使导管偏转。 聚合物材料在被施加时可以被加热成熔融形式，或者可以加热芯心轴或衬里以使聚合物材料在冲击时固结。 优选实施例中的心轴围绕其纵向轴线旋转，同时喷头和细丝缠绕头横穿心轴的长度并分别施加聚合物材料和细丝。 还可以使用其它布置，包括围绕连续芯心旋转的喷头和细丝缠绕头，以及浸入加热芯心的流化床或其它容器。 多个心轴可以并排放置以形成多管腔管。

    Abstract: Apparatus for the production and proper calibration of improved flexible hoses made by a soft thermoplastic material reinforced with a continuous spiral of rigid thermoplastic material. During their production the hoses do not rotate but are produced linearly and in their internal surface no longitudinal grooves are engraved. The melted coaxial materials are discharged through a rotating mechanism to a calibration unit which rotates with it and bears peripherally special inclined rollers on which is transmitted, via an epicyclic gearing system, a controlled rotation opposite to the above direction. On this calibration unit the plastic hose is formed successively, advancing linearly forward.

    Abstract: This disclosure relates to a hose including a tube and a braided wire reinforcement covering the tube. The wire braid includes a plurality of interwoven strands of wires, and each strand includes a plurality of wires having a uniform tension and a twist of from approximately one turn for each two and one-half to three inches. Further, each of the wires of the strand is preformed to produce a helical tension spring configuration, and the strands are braided under a relatively high tension. The hose is made by a method including the steps of preformng wires to produce the helical tension spring configuration, combining a plurality of such wires under a uniform tension and twisting such wires to form strands, and braiding a plurality of such strands under high tension.
