Vessels and Braces
From heart stents to dental wires: Nitinol inside the body.
- Internal Logic
The Biological Fit
Nitinol is biocompatible, meaning the body doesn't reject it as a foreign invader. This makes it a perfect candidate for permanent internal implants.
- Mechanism
Thermal Trigger
Medical Nitinol is engineered to activate at 37°C (98.6°F). It uses the body's own natural heat to trigger its shape transformation.
- Turning Point
The Stent Revolution
Before Nitinol, stents were rigid and prone to breaking. Nitinol allowed for flexible scaffolds that move with the pulsing of an artery.
