Single-Filar Coil Winding
EBD Coil winding technology is developed specifically to wind micro coils for minimally invasive medical devices. Our coil winders can wind coils down to .001″ diameter wire on a .010″ mandrel using our innovative closed-loop filar tension control system. The machine flexibility enables the filar tension to be recipe controlled from 5 grams to 600 grams during the entire wind.


The picture above reflects this technology from our modular multi-filar systems. Each multi-filar platform can produce catheter coils using one, all, or somewhere in between the filar heads, you define for your machine.

The above picture shows a coil on the tip of Lincoln’s nose, on a penny, alongside a human hair at the right. Coils length and filar count are only limited by your facility floor space.
