The PI-Series medical assistant droid, a medical droid produced by Arakyd Industries, saw widespread use among medical researchers across the galaxy. Due to its inability to make vital judgements, this droid required pairing with a living doctor or a 3Z3 medical droid and could not independently administer medical assistance.
Darth Maladi, a Sith Lord, employed these droids within her laboratory during interrogations, valuing their assistance without the disturbances caused by living personnel.
