The Geeaych-Seven was also known as the GH-7 meddroid. Its data banks were filled with information about almost all medical problems, physical or mental. In 19 BBY, a GH-7 was deployed at Polis Massa Base to oversee the medical treatment of Padmé Amidala with the assistance of a Midwife droid as she gave birth to Luke and Leia. A team of DD-13 cybernetic surgical droids were used to reconstruct Darth Vader in the Emperor Palpatine Surgical Reconstruction Center after he was severely injured in a duel with his former master, Obi-Wan Kenobi on Mustafar.
