Publication number: 20130138204Abstract: A stent that is extremely useful in practice, with excellent proof stress (elastic limit stress). The stent (1) is in a tubular shape that is expandable in a radial direction, the stent being placed in a tubular vessel of a living body. The stent (1) is formed of a main stent element (2) that is formed at an imaginary cylinder surface. The main stent element (2) is fabricated of an alloy with a proof stress of from 500 to 2700 MPa, or is fabricated of an electroformed alloy with a repetition fatigue strength at least 1.5 times the strength of a nickel member or a nickel/cobalt alloy member, which is an alloy containing any of gold, silver, copper, nickel, cobalt and palladium. Therefore, the stent (1) may be easily and uniformly expanded in the radial direction, and is not easily crushed in the radial direction after being expanded.Type: ApplicationFiled: August 10, 2011Publication date: May 30, 2013Applicant: OPTNICS PRECISION CO., LTD.Inventors: Seichin Kinuta, Takashi Kawabata
