A medical device (150, 320, 340, 350, 370, 420, 450) that inhibits distortion of medical resonance images taken of the device. In particular, various structures are utilized to allow visibility proximate, and inside of, a tubular member, such as a stent. In one embodiment, the stent does not contain electrically conductive loops. In an alternative embodiment, rings in the stmt are arranged such that current in one ring portion is opposed by current in another ring portion. |
