The present invention relates to an in vivo indwelling member which has loop-shaped parts, and a shape complicatedly curved in various directions. The in vivo indwelling member easily spreads inside the aneurysm during development due to strength thereof, is hardly entangled, and is easy to unravel, even if the in vivo indwelling member is concentrated in an overlapping manner. The in vivo indwelling member can maintain good operability and prevent the rupture and damage of the aneurysm. The in vivo indwelling member includes a plurality of loop-shaped parts (R01, R11, R21 to R23), each of which extends one turn or more to form a loop, the plurality of loop-shaped parts formed of loop-shaped parts with at least two different loop lengths from a tip end side of a primary coil toward a base end side of the primary coil.

A method for forming a wire into a coil spring includes winding the wire around a coiling mandrel to form the wire into a cylindrical coil shape, clamping one end of the wire formed into the cylindrical coil shape, clamping an intermediate portion of the wire spaced from the clamped one end of the wire; and moving the clamped one end of the wire relative to the clamped intermediate position at least in an axis direction of the cylindrical coil shape, whereby a pigtail having a desired shape is formed.

A moldable wire thread insert for reinforcing a screw-in opening of a component has the following characteristics: a cylindrical spiral made of a helically, wound wire, the neighboring coils of which are arranged such that a closed cylindrical spiral wall is present, while at least one end of the cylindrical spirals has a fastening flange, which extends radially outwards over the cylindrical spiral wall and with which the wire thread insert is anchorable in the component and/or one end of the cylindrical spiral is designed in a planar manner in order to form an even axial front surface of the cylindrical spiral.

Systems and methods are provided for wire processing. In certain examples, a wire processing system may be disclosed. The wire processing system may include a wire transport, a processing station that may provide wire to the wire transport, a processing station that may move an electrical component threaded onto the wire, and a processing station that may move the electrical component to a position on the wire for further processing.

A production method for a medical linear member is provided which is not abraded upon production and which includes a flat shape in a cross section.

The method includes the steps of: forming a first spiral body (1) of an oval shape in a horizontal section by spirally winding a base body (3), in which a plurality of wires (2) formed of a shape-memory alloy is arrayed, around a winding core (4); subjecting the first spiral body (1) to first shape-memory treatment; cutting the first spiral body (1) into a first predetermined length; forming a second spiral body (5) of a flat shape in a horizontal section by compressing the first spiral body (1) in a direction along a short diameter; subjecting the second spiral body (5) to second shape-memory treatment; and removing the winding core (4) from the second spiral body (5).

A mechanism for producing coil springs (10) includes a winding stage (110) for engaging with a wire (20) and deforming the wire (20) to coil windings as the wire (20) moves through the winding stage (110). Further, the mechanism comprises a feed mechanism (120) configured to feed the wire (20) to the winding stage (110). Further, the mechanism comprises a rotary cutter (130). The rotary cutter (130) is configured to cut the deformed wire (20) into portions forming separate coil springs (10) and a blade (135) which is driven for rotation about a stationary rotation axis.

A servo-rotating all-function tool module is provided for use with a spring forming machine and includes an axle rotating tool module and a servo transmission module assembly. The axle rotating tool module is rotatably mounted, in combination with an axle of the rotary axle assembly of the spring forming machine, to a front wall board and includes an oscillating base and a tool. The oscillating base is rotatably mounted to the rotary axle assembly. The tool is mounted to an end of the oscillating base. The servo transmission module assembly is mounted to the spring forming machine and includes a servo moving ring circumferentially surrounding the oscillating base for driving the oscillating base to oscillate in all directions to thereby cause the tool to press down or lift upward.
