If I recall, with Garfield's assassination, Alexander Bell tried to use a metal detector to locate the bullet. Garfield was laying on the new metal spring coiled Slumber 3000, and the metal coils interfered with the metal detector finding the bullet, although they didn't realize it at the time. They just thought the metal detector didn't work. We will never know if he might have survived if they could have taken the bullet out.
