An intravascular stent,has an elastic self-expandable cylindrical stent proper,. The stent proper,is connected to metal support wires,that are long enough to reach outside of the body of a patient through a catheter,. Manipulation of the support wires,pushes the stent proper,into a blood vessel from within the catheter, thereby allowing it to expand there, and then contracts and retracts the stent proper,into the catheter,, repeatedly.

A plated nickel-titanium alloy product having a plated layer of nickel or a nickel alloy containing 5 to 15% by weight of cobalt. This product exhibits excellent surface treatability and workability, as well as shape memory effect and super-elasticity. Thus the product is most suitable for eyeglass frame components or similar ornamental articles. The product is produced by plating a layer of nickel or a nickel-cobalt alloy on the nickel-titanium alloy, dehydrogenating, cold working with not less than 10% working ratio, and subjecting to a final heat treatment between 300.degree. C. and 900.degree. C. If the final heat treatment is conducted between 750.degree. C. and 900.degree. C. for 10 to 120 seconds, a product with 4% or more super-elasticity at room temperature can be obtained.

Plated nickel-titanium alloy product

An eyeglass temple has an arm whose forward end is connected to one of a pair of eyeglasses or to one end of a rim holding a pair of eyeglasses and an earpiece continuing from the rear end of the arm is made up of a plastic temple proper and a core buried in the plastic temple proper so as to extend in the direction of its length. A portion of the metal core buried in the arm has extra-high elasticity, whereas a portion in the earpiece has plasticity.
