Double-butted superelastic nitinol tubing

机译:双对接超细镍钛合金管

摘要

A medical device such as a stent made from single or double-butted tubing is disclosed. The butted tubing may be made from stainless steel or a nickel-titanium (nitinol) alloy. The butted tubing is created by thinning the material in between the ends of the tube through machining, drawing, cold working, laser cutting, or chemical etching. A strut pattern for a stent is laser cut into the butted tubing. The strut pattern for the stent includes rings connected by links. The end rings of the stent coincide with the double-butted ends of the tubing thereby increasing the hoop strength of those end rings.
