A missing body part that now comes with firmware updates and warranty cards.

means An artificial device that replaces a missing or damaged body part, restoring function or form.

from From the Greek 'prosthesis,' meaning 'addition' or 'attachment' — itself built from 'pros' (toward, in addition to) and 'tithenai' (to place). The word entered medical and grammatical usage alike, originally describing anything attached to make a thing more complete, before narrowing in English to its familiar sense: a replacement limb or part added to a body that's missing one.
