At the very least, ALL technology information, including all designs, source code, notes, studies, support logs, etc. is placed in escrow with the appropriate govt agency. If the company (or its successors) is unwilling/unable to provide continuous and effective support for the implants & associated tech, it is all open-sourced / becomes public domain. This provides at least the tech basis for minimal right to repair/remove to other physicians.
