Built for miniaturization. Engineered for impact.
As medical devices get smaller and more sophisticated, it’s advantageous that the materials inside them do more than ever before. DFT® wire is a dynamic composite wire construction with multiple capabilities that help power implantable neurovascular and cardiac rhythm management devices.
Here’s how it works: An outer sheath made from 35N LT™ alloy, Nitinol, or other high-performance alloys provides strength and biocompatibility, while the core material—such as gold, platinum, or silver—adds functionality through conductivity, radiopacity, resiliency, or MRI enhancement.
Two materials in one are customized to meet the increasing constraints of miniaturization and the complexity of applications. Available in diameters as small as 0.017 mm [0.0007 in], DFT® wire is a bio-conductive powerhouse that elevates performance without compromising on size.
Sheath materials:
- 35N LT alloy
- FWM 1058 alloy
- Nitinol
- Platinum alloys
Core materials:
- Nitinol
- Platinum
- Silver
- Tantalum
Typical devices include:
- Aneurysm coils
- Conductors
- LVAD driveline cables
- Neurovascular stents
- Pacing leads
- Retrieval baskets
- Shock coils
- Vascular stents
Recent innovation
A more recent advancement supports the work of medical providers who have long faced limited visibility of devices during X-ray imaging, often relying on markers that can create visual interference.
Helping solve this problem is our Nitinol DFT® wire, which incorporates radiopaque platinum or tantalum core within a Nitinol sheath. Learn more here: Optimizing medical devices: The effect of platinum on Nitinol DFT® composite wire
Our Nitinol DFT® flat wire (platinum core only) goes a step further by delivering greater, continuous radiopacity at the same thickness as round wire, enabling clearer visualization without additional components. As medical devices continue to miniaturize, Fort Wayne Metals will keep pace by developing new material technologies. Explore the capabilities of DFT® wire.
