As an innovations journey from conception towards FDA approval, the intricate dance between innovation, safety, and the promise of enhancing human health becomes evident. Histopathological evaluations illuminate the complex interactions between medical devices and the human body, focusing on crucial aspects such as implant location, device function, potential failures, and the biological response to the device. This rigorous analysis ensures the device’s placement within targeted tissues, checks for any unwanted migration, and measures how well the device operates within the biological milieu. Furthermore, it reveals issues such as impedance rise due to fibrotic encapsulation, mechanical damage, or material degradation due to oxidative stress. Such detailed examinations provide invaluable feedback, guiding researchers and developers in refining device designs to enhance safety, functionality, and patient outcomes. One common medical implant that requires all four leading use cases for conducting histopathology are brain computer interfacing implants (Figure 1).
