DFT® Nitinol flat wire

DFT® Nitinol flat wire integrates Nitinol's shape memory and superelastic performance with a radiopaque core in a flat wire form, ultimately providing both device flexibility and improved visibility under X-ray.

장점 이해하기

The better healthcare professionals can see a device on an X-ray, the better they can detect and treat medical issues. And yet, medical providers have long dealt with an ongoing problem: limited visibility of devices under X-ray. Nitinol wire, while offering shape memory and superelasticity, requires radiopaque markers to be visible during examinations. However, our teams recently leveraged our capability to use dissimilar materials in a single wire system with the introduction of DFT® Nitinol flat wire.

Here's how it works: Nitinol serves as the outer sheath with platinum as the core, enabling users to view the entire medical device under X-ray and virtually eliminating the need for attaching radiopaque markers. This benefit of improved radiopacity now, available in a flat wire form, also means increased device strength while retaining equivalent material thickness.
