The complaint received identified that a fragment of the electrode was left behind in the patient after the electrode was removed.After visual inspection of the returned product, it is clear that the electrode tubing sheared between the third and fourth contacts.This likely occurred due to the force applied when pulling the electrode out.The information provided about the electrode not going in smoothly indicates that the electrode may have been off angle slightly, and because of that, when it was pulled out it may have caught on the anchor bolt which could have caused the electrode to break.
