Medical devices (150, 300, 690) that suppress distortion of medical resonance images received from the device. In particular, by using various structures, the vicinity of the tubular member such as the stent (150, 300, 690) and the inside thereof are visualized. In one embodiment, the stent is configured such that any closed path that surrounds at least the periphery of the stent passes through at least two materials, thereby reducing or eliminating electrical loops formed within the stent. . |
