Abstract
A method of making a superelastic medical device with a radiopaque marker includes threading a radiopaque marker having an elongated shape over a wire comprising a shape memory alloy. After the threading, the wire is secured in a predetermined configuration to a mandrel. While secured to the mandrel, the wire is heat set in an environment comprising an inert gas so as to impart a memory of the predetermined configuration to the wire and superelastic properties to the shape memory alloy. A superelastic medical device including the radiopaque marker is thus formed.
