Ternary alloys answer radiopacity problems binary nitinol cannot
A neurovascular device has to be visible under fluoroscopy in vessels a couple of millimetres across, and binary nitinol is close to invisible at those wall thicknesses. Adding platinum or palladium raises radiopacity without destroying the transformation behaviour, though it narrows the processing window considerably and costs a great deal more per kilogramme. Growth at 13.8% follows neurovascular and cardiac implant procedure volumes rather than any material development programme. The supplier base here is narrower still than for binary alloy, because ternary melt chemistry is harder and the volumes do not justify anybody learning it speculatively.
