SELF-CRIMPING RADIOPAQUE MARKER

摘要

A radiopaque marker band includes a tube having an inner surface and an outer surface. The tube is made from a shape- memory material, such as a nickel-titanium alloy. A coating is disposed on at least a portion of the outer surface of the tube. The coating has a greater radiopacity that said shape-memory material. The coating may be applied in a plurality of bands on the outer surface of the tube.
