Abstract: An implant can include a single- or dual-layer braided body having a variable porosity. In a dual-layer body, first and second longitudinal sections, having respective first and second porosities, can be overlapped such that the first and second porosities overlap each other. The dual-layer construction can cumulatively provide a third porosity at a distal portion and a fourth porosity at a proximal portion. The third and fourth porosities can each be greater than each of the first and second porosities.

Abstract: A three-dimensionally shaped round metallic wire having a cross-section non-circular portion in a predetermined portion without performing additional processing and having specified dimensional accuracy and accuracy of form. In an intermediate step in which the round metallic wire is processed in a predetermined three-dimensional shape, a cross-section non-circular portion forming machine 20 which forms the cross-section non-circular portion having a non-circular cross-sectional shape in at least one position is included. At the time of bending, the cross-section non-circular portion is held by a wire holding portion of a bending machine 30, and the bending is performed in the predetermined three-dimensional shape. Holding the cross-section non-circular portion causes relative rotation between the cross-section non-circular portion and the wire holding portion to be suppressed as compared with a case of the cross-section circular shape.

Abstract: In thickness control processing, transfer processing of an entry thickness He(N) is performed (step S1). In the transfer processing, data of the entry thickness He(N) is transferred from a position P11 to a position P12 at the same speed as the speed of a material to be rolled M. Subsequently, an amount of change in a thickness ?H(N) is calculated (step S2). The amount of the change in the thickness ?H(N) is calculated based on data of a delivery thickness Hd(N) and data of a transferred thickness Hc(N) transferred to the position P12 at a timing when the data of the delivery thickness Hd(N) is measured. Then, a target entry thickness He(N)_tgt is calculated (step S3). Subsequently, a manipulated amount of rolling speed VR(N?2) and VR(N?k) are calculated (step S4).
