A radiopaque component is included in manipulation and retrieval devices useful for kidney and bile stones. These devices may include a retriever or manipulator, to remove a stone or other object from a body. Metallic three component alloys of Ni-Ti and at least a third metal are useful for their radiopacity. Manipulators, graspers, nets, jaws, and other retrieval devices or end-effectors may be made with such alloys. |
