But without notifying these users, the company suddenly collapsed in 2020, leaving patients with obsolete technology in their bodies that cannot be upgraded, supported or easily repaired. So now what? Harris and his coauthor describe how patients and doctors are coping, and they outline a cautionary tale as neuromodulation devices become a reality for more people.
