Connecting lives
with invisible precision

Precision thin-film surface
conductor technology

Easy sensor implementation

Features

Superior Guidewire Mechanical Performance

The technology minimizes the impact of the electrical elements in any instrumented guidewire application by condensing the electrical circuits into an ultra-thin film on the surface of the substrate. The technology is applicable to small diameter or tapered areas, and is compatible with graduated stiffness profiles and downsizing of devices.

Unparalleled Design Freedom

Trace widths and layouts are infinitely adjustable. The number of traces, along with parameters such as each trace’s impedance, can be designed to fit the application.

Flexible Choices in Material

Freedom to choose from multiple base material for both conductive and non-conductive elements.

Easy to Integrate

Ability to align the end zones for all traces on the same plane facilitates easy integration of sensors.
