摘要： A stent having marker tabs formed from a micro-alloyed combination of materials provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. A unique micro-alloying process is utilized to form the tabs, comprising a first alloy and a second alloy, wherein one of these alloys is radiopaque. This substantially eliminates the possibility of galvanic action between the tab and the stent. This process is also applicable to other medical devices.

摘要： A stent for use in a lumen in a human or animal body, has a generally tubular body formed from a shape memory alloy which has been treated so that it exhibits enhanced elastic properties with a point of inflection in the stress-strain curve on loading, enabling the body to be deformed inwardly to a transversely compressed configuration for insertion into the lumen and then revert towards its initial configuration, into contact with and to support the lumen. The shape memory alloy comprises nickel, titanium and from about 3 at. % to about 20 at. %, based on the weight of the total weight of the alloy composition, of a ternary element selected from the group consisting of niobium, hafnium, tantalum, tungsten and gold. The ratio of the stress on loading to the stress on unloading at the respective inflection points on the loading and unloading curves is at least about 2.5:1, and the difference between the stresses on loading and unloading at the inflection points at least about 250 MPa.

摘要： A stent assembly comprises a stent whose configuration can change between a transversely compressed state for delivery into a lumen in a human or animal body, and a relaxed state in which in use the stent contacts the lumen to support it. The stent is positioned in a delivery device and constrained by it in its transversely compressed state. The delivery device comprises a tubular member formed from a shape memory alloy and can be fitted to or within a catheter for delivery of the stent through a lumen.

The stent is made from a tubular member a thickness, front and back open ends, and a longitudinal axis extending therebetween. The member has a first smaller diameter for insertion into a vessel, and a second larger diameter for deployment into a vessel. The tubular member has a plurality of adjacent hoops extending between its front and back ends. The hoops are formed of a plurality of longitudinal struts, each having opposing ends and a center therebetween. The ends of the struts are shaped to form a plurality of loops which connect adjacent struts at the ends of the struts. The member further includes a plurality of bridges connecting adjacent hoops to one another. Each of the struts has a width which is greater at its ends than at its center. Preferably, the width continuously tapers from a greater width at the ends to a smaller width at the centers.

摘要： Very finely granular metal powders are produced by atomizing a liquid jet of metal by means of a gas jet which, in addition to a continuous band of sound frequencies, contains at least one discrete sound frequency which is at least 5 decibel above the average intensity of this band, and which is generated in a rotationally symmetrical device by means of a nozzle (4) which has the shape of a hollow cone and by means of an annular resonance space (7) with an annular edge (6) and is projected concentrically against the liquid jet of metal at a total opening angle of an average 35.degree. to 55.degree.. The atomization zone of the gas jet should preferably contain at least three discrete sound frequencies which are each at least 10 decibel above the sound intensity of the continuous band.

摘要： An article in rod, tube, strip, sheet or plate shape with reversible thermomechanical properties is produced by joining of at least two parts consisting of a total of at least one shape memory alloy having a two-way effect, whereby each part has a memory effect by itself. In the case of at least two shape memory alloys (1, 2) with different transition temperatures but the same mode of movement, the joining of the individual parts can take place prior to the deformation in the low temperature range necessary to inducing the two-way effect. In the case of differing types and degrees of movement of the individual parts (25, 26), their joining can first be accomplished only after the individual deformations of each part for itself in the low temperature range are accomplished regardless of how many shape memory alloys with different transition temperatures are used in the structure of the article.
