Endoprosthesis, useful as stent in artery, vein, bile duct, airway or gastrointestinal tract, consists of metal with specified magnetic susceptibility and structure avoiding electric circuit perpendicular to axis

摘要

Endoprosthesis consists of a metallic material (I) with a magnetic susceptibility in the -300 x 10-6 to 300 x 10-6 range. It has an axis and circumference and is designed in such a way that the individual stays or wires along the axis are oriented so that no continuous electric circuit forms in a plane perpendicular to the axis over the circumference of the prosthesis.
