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.

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.

The invention is a method for forming a continuous strand of wire into a spiral support structure. The method includes winding a continuous strand of wire around a first central axis into a primary spiral. The primary spiral thereafter is stretched linearly to form an elongated spiral of desired pitch, which is then wound around a second central axis to form spiral support structure. This resulting spiral support structure can have two or more sides. The amount of sides depends on ratio of first axis to the second axis along with the pitch of the spiral. The crest and depressions of the structure are linearly aligned, and are parallel to each other.

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 transfer device for limiting a twisting of a link between an end of the fixed link with respect to a fixed part and an end of the fixed link with respect to a revolving part that can revolve with respect to the fixed part about an axis of rotation, the transfer device for a link includes a composite drum comprising a set of drums aligned on the axis of rotation about which the link can be wound, the set of drums comprising a fixed drum intended to be secured to the fixed part in rotation about the axis of rotation, a revolving drum intended to be able to revolve about the axis x with respect to the fixed part and a set of at least one loose drum interposed between the fixed drum and the revolving drum, each loose drum being free to rotate about the axis of rotation with respect to the revolving drum and the fixed drum and having a height on the axis.

A method for winding a rectangular wire in a winding space of a coil former or of a winding tool to form a linearly wound coil, wherein the rectangular wire in the winding space is wound in at least one layer in an axial laying direction. Before the coil is wound, a guide device is introduced at least partially into the winding space, and the guide device has, in the laying direction, a stop which delimits the rectangular wire in the laying direction; the guide device is entrained, during the winding process, as the winding of the coil in the laying direction increases; and the guide device is withdrawn from the winding space before the last winding is wound in front of a second lateral stop. A linear winding device for performing the method is disclosed.
