  • Patent number: 7257897
    Abstract: A cutting device for trimming a coiled strand, such as an arterial, urinary or other intraluminal stent made from metal or plastic wire, has a pair of articulating arms connected at a pivot joint. One of the arms has a holding jaw for holding the coiled strand. A second of the arms has a jaw with a cutter. The holding jaw has a passageway through which the coiled strand may be threaded to aid in holding the coiled strand for cutting by the cutter. The holding jaw preferably has a guide channel formed by a pair of tapered walls that slide between adjacent turns of the coiled strand. In accordance with a method of the invention, an end of the coiled strand is introduced through the passageway in the holding jaw. The coiled strand is rotated to advance the coiled strand through the passageway until the coiled strand is positioned beneath the cutting jaw at the selected location. The lever portions and the jaw portions are then urged together, cutting the coiled strand at the selected location.

  • Patent number: 4995251
    Abstract: The instant invention is an improvement on a method of making wire coils comprising the steps of rolling a length of wire having a leading end and a trailing end and displacing the wire in a longitudinal travel direction and coiling the wire into succeeding overlapping loops and depositing same onto an upstream conveyor. The loops are transferred from the upstream conveyor to a downstream conveyor and are deposited from the downstream conveyor onto a centering device to form a coil thereon. The downstream conveyor is driven to move the loops at a generally constant slow transport speed but the upstream conveyor is driven to move the loops at a substantially faster transport speed when loops of a portion of the wire having one of the ends are being deposited on the upstream conveyor. Otherwise the upstream conveyor is driven at the same slow speed as the downstream conveyor so that the loops of the end portion will be spaced more in the travel direction than the other loops of the wire.
