摘要： An apparatus for compressing a coiled stent having at least one protrusion, such as an enlarged coil disposed at the end of the stent, has a mandrel insertable into a lumen of the stent for holding the stent by friction and a coil compressor coupled to the mandrel. The mandrel is rotatable on an axis relative to the coil compressor and the coil compressor has a tab extending therefrom towards the mandrel. A stent is placed on the mandrel with the enlarged coil extending toward the coil compressor. The tab presses the enlarged coil inwardly toward the lumen of the stent when the mandrel is rotated relative to the coil compressor.

摘要： The present invention relates to resorbable glass scaffolds for use in biological applications and methods for making same. Specifically, these scaffolds are composed of phosphate glass fibers, where the rate of dissolution into biological fluids is controlled by the length of time the glass is held above its melt temperature prior to spinning the fiber.

摘要： 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.

摘要： An orthopedic screw with an internal bore and mating driver has a bioabsorbable polymer component. To increase the torque tolerance of the screw and to minimize the likelihood of the driver stripping inside the bore of the screw, the screw and driver are heat treated together to shrink fit the screw onto the driver thereby increasing the driver-to-screw contact and distributing the loading force over a greater area to protect against material failure. The heat treatment involves heating the screw to an elevated temperature and holding that temperature for a period to promote stress relaxation and/or crystallization of the material.
