A medical device includes a body comprised substantially of radiolucent material and a radiopaque marker. The radiolucent material does not obscure images or radiographs during fluoroscopic visualization. The radiopaque marker is detectable during radiological imaging. The radiopaque marker may produce a readily identifiable image according to the type of medical device. The marker may further be configured to produce a magnetic field or transmit signals for noninvasive detection using a sensor. The field and signals may be unique for each type of medical device.
