Abstract
An expandable metallic stent has discontinuities of non-conducting material. These eliminate electrically conducting paths in the stent rings and cells. This makes the stent easier to image with magnetic resonance imaging (MRI). The non-conducting material can include adhesives, polymers, ceramics, composites, nitrides, oxides, silicides, and carbides. The discontinuity is preferably shaped so that during expansion the discontinuity is placed in primarily a compressive stress.
