Forum:KB:Anakin's slave implant

I've noticed that in the Star Wars Blueprints: The Ultimate Collection no where in the Darth Vader blueprint does it show Anakin's slave implant. I know that in Episode I they mention him having one and I read his page and there wasn't any information there (at least that I saw). Was Anakin's slave implant removed?
