Flexibility of radiopaque marker is achieved by using a segmented band of radiopaque material or a coiled band formed by winding a wire or hollow tube filled with radiopaque material. The flexible radiopaque marker may be affixed with the shaft by an adhesive, by swaging, by crimping, by soldering, or by spring-action tension fit against the shaft.
