    摘要： A method of forming a catheter comprising the steps of a) loading an inner layer on a mandrel; b) loading a reinforcing braid layer over the inner layer; c) adding a terminal tip to one end of the inner layer, the terminal tip applied directly over the inner layer with no portion of the reinforcing braid therebetween; d) loading a plurality of axial jacket sections over the braid layer, one of the axial jacket sections engaging an adjacent one of the plurality of axial jacket sections along a joint including substantially axially oriented seams; e) applying a shrink tube over the plurality of axial jacket sections and heating the shrink tube to cause the plurality of axial jacket sections to bond with each other, the braid layer and the inner layer; f) removing the shrink tube; and g) removing the mandrel. An aspect of the process relates to annealing an end of the braid layer and using a plastic sleeve compressed and melted about the annealed end to insure that the end of the braid layer lies flat on the inner layer. Where plural axial jacket sections are used, they are welded together by joints which include substantially axially oriented seams. In another embodiment, the axial jackets can be combined in a single coextruded, monolithic form having varying durometer and/or material compositions.

    摘要： First and second semi-finished molded articles and a third semi-finished molded article are molded simultaneously so as to have joint end faces by using a slide die, a fixed die, and first and second slide cores fitted to the fixed die. The slide die with the third semi-finished molded article remaining thereon is moved toward the first and second slide cores, and their respective joint end faces are registered. Heating surfaces are inserted between the joint end faces. After melting the joint end faces, the heating surfaces are retracted, and the molding device is closed to weld the joint end faces.

    摘要： An internal molding having a predetermined shape of a hollow portion of a manifold is integrally molded by blow molding or the like, and external molding elements having a predetermined shape of the exterior of the manifold and being split into a plurality of parts are molded. The internal molding is integrated with the external molding elements by adhesion or fusion. Further, an external molding is molded, and an internal molding having a shape substantially identical with or smaller than a predetermined shape of a hollow portion of the hollow resin molding is integrally molded. Then, the internal molding is softened by arranging the internal molding inside the external molding and heating the internal molding, and the inside of the internal molding is thereafter pressurized to cause the internal molding to contact the external molding, so that the internal molding is integrated with the external molding. Still further, an internal molding is integrated with an external molding elements by an appropriate joining means. Then, a flange member is fitted to a first connecting portion formed by the respective external molding elements and the internal molding. Still further, an internal molding is integrated with an external molding elements by an appropriate joining means. Then, a seal member is inserted into a gap portion at an end portion of the hollow resin molding as well as between the external molding and the internal molding.
