Why do medical implants like insulin pumps and prosthetic knees need replacement? Explore how the immune system fights implants and how new devices are trying to help.

--

Insulin pumps improve the lives of millions of people with diabetes around the world by monitoring blood sugar, delivering insulin, and preventing the need for constant finger-pricking.

Kaitlyn Sadtler details how our immune system reacts to foreign bodies.
