Abstract
A medical device 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 is constructed such that any closed path encircling at least a circumference of the stent will pass through at least two materials to reduce or eliminate electrical loops formed in the stent.
