A wiring machine includes a lever group and magnets. The lever group includes a plurality of lever arms which are spaced apart and a plurality of rotary shafts on each of which one lever arm is mounted correspondingly so as to facilitate the rotate rocking motion of the lever arms. One end of each lever arm is provided with a wire gripper and the other end is provided with an attraction head. The magnets are arranged in association with the plurality of attraction heads.

A device for coiling an elongated flexible object into a predefined shape includes a length of wire which is formed with a minor winding and a major winding, the minor winding having an axis corresponding to the longitudinal axis of the object and being configured to conform to the cross section of the object, and the major winding being configured to conform to the predefined shape. In use of the device, the minor winding secures the device to the object and the major winding coils the object into the predefined shape.

Disclosed are example embodiments of an endovascular coil having a twisted figure 8 shape. The endovascular coil includes: a first loop; a second loop; and an inflection region where a portion of the first loop transitions into a portion of the second loop. The second loop is rotated about an axis parallel to the longitudinal axis of the first loop to create the twisted figure 8 shape. The twist adds more randomness and variability to the filling behavior of the endovascular coil. The added randomness and variability enables the twisted figure 8 coil to better fill the void of irregular-shaped aneurysms than other conventional embolic coils.

A flat embolic braid having a first side comprising a first side surface, and a second side comprising a second side surface facing in an opposite direction than the first side surface, the braid having an elongated constrained configuration for being deployed through a delivery catheter, and a three-dimensional unconstrained configuration, wherein in the three-dimensional unconstrained configuration, the braid assumes a plurality of successive loops in which the braid is at least partially twisted between successive loops of the plurality, so that the first side surface faces externally of each loop, and the second side surface faces an interior of each loop, respectively, regardless of a change in direction and/or orientation of the braid.

A hollow stranded wire (2) has a first layers (4) and second layers (6). The second layer is located outside the first layer. The first layer is formed by twisting eight first element wires (8) which are flat wires. The second layer is formed by twisting eight second element wires (10) which are flat wires. A ratio (Ww/Tw) of a width Ww to a thickness Tw of each flat wire is from 2 to 11. A twisting direction of the second element wires is opposite that of the first element wires. A twisting angle of each first element wire is not greater than 85. A twisting angle of each second element wire is not greater than 85. A ratio (D/T) of an average diameter D to a thickness T of the hollow stranded wire is not less than 5 and not greater than 20.

A winding apparatus 23 forms a rectangle-tubular edgewise coil 1 by alternately repeating bending of a rectangular conductor 2 in a clockwise direction in a plan view in an edgewise manner and feeding of the rectangular conductor 2. The winding apparatus 23 includes a bending jig 31 configured to bend the rectangular conductor 2, five sway-prevention guides 50 arranged at regular intervals on the same circumference to prevent the edgewise coil 1 from losing its shape, the five sway-prevention guides 50 being configured so that when the rectangular conductor 2 is bent in the edgewise manner, the edgewise coil 1 is sandwiched between two adjacent ones of the five sway-prevention guides 50 in the clockwise direction, and a guide holding member 51 configured to be rotationally driven in synchronization with the bending of the rectangular conductor 2 in the edgewise manner and the feeding of the rectangular conductor 2.
