The Evo Advantage

Decreased Immunological Response
Single Tail Design
Reduced Cable Management

The Evo Electrode is over 7 times thinner than a silicone electrode. The flexibility and reduced volume should reduce pain and edema.2

The Evo’s polyimide substrate has properties like increased flexibility,
reduced volume, and decreased immunological response, which should reduce signal artifacts.

The single thin tail design allows the implanted electrode tail to be tunneled through one incision which should reduce infection risk and procedure time.1,2

A disposable cable assembly is sent with each Evo Electrode as an electrode kit, removing the need to source the correct cables for each electrode being used in surgery. Also, hospital resources are freed from the management of sterilizing and storing individual electrode cable assemblies.

Portfolio of Strips and Grids

The Evo Cortical Electrodes are designed to provide more surgical implant options, decrease infection risk and better mapping capabilities

Evo is manufactured using a fully automated Laser Direct Imaging (LDI) process to deliver precision and scalability of the electrode.
