A solenoid includes a tubular core formed of a magnetically susceptible material, an annular electromagnetic coil disposed about the tubular core, and an armature assembly received in the tubular core and movable relative to the tubular core along a longitudinal axis of the tubular core. The armature assembly includes an armature and a polymer material. The armature is formed of a magnetically susceptible material and has an armature surface that is disposed about the axis of the tubular core. The polymer material is fixedly coupled to the armature and is uniformly disposed over the armature surface. A method for forming a solenoid is also provided.

An embolic microcoil can be formed into a complex shape for use in treating aneurysms and other vascular disorders. The microcoil features a distal portion including several loops that together comprise a substantially spherical shape, and an elongated proximal portion that is deployable within the distal portion. The distal portion can create a stable frame with adequate loop coverage across a neck of the aneurysm. The proximal portion can include a series of substantially omega-shaped loops, which can apply a force against the interior of the substantially spherical shaped distal portion, expanding it into apposition with additional portions of the aneurysm wall. Methods of treating vascular disorders and methods of manufacturing certain microcoils are also disclosed.

The present disclosure relates to an automatic forming machine for plant growth supports, comprising a ring rolling system with a ring rolling unit, a mold system with a mold unit, and a welding system, which are all disposed on a machine frame, wherein the ring rolling unit can roll a metal wire and make the metal wire be formed into a ring with an opening in the mold unit; the mold system is for carrying the ring and making two free ends of the ring with an opening aligned or alternately overlap with each other; the welding system welds can weld the opening of the ring carried by the mold unit, causing the ring to become a closed ring. The present disclosure has a high automatic degree and can reduce the production time and labor cost.

A wave winding device for manufacturing wave windings has a winding unit with a winding blade device rotatable about a winding axis in a winding direction and on which a winding wire is to be wound. The wave winding device has at least one wire feed device that supplies the winding wire to the winding unit in a feed direction to wind the winding blade device, and also has a transport device for transporting the winding wire, which is wound onto the winding blade device to form a wave winding, in a transport direction parallel to the winding axis. The transport device has a conveyor system that moves the wave winding through the transport device in the transport direction. The conveyor system is supported in the transport device so as to be rotatable about a rotational axis in the winding direction, coaxially with respect to the winding axis.

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.

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.

The present invention is an apparatus, system and method for a new and improved coiling head utilized in wrapping elongated materials, which may have a zero and or near zero gap between leaves thereby reducing and or elimination indentations in the coiled elongated materials.
