The complaint was confirmed.Overuse of the electrodes (sterilizing units beyond the number of cycles the units are validated for) can lead to additional wear on the units and the epoxy inside the hub, leading to cracks that allow for fluid ingress.The lab determined that the material found on the hub contained proteins like those found in blood.
