Implanted medical devices like stents, catheters, and titanium rods are essential, however sometimes the body rejects them or they cause dangerous blood clots. Engineers and scientists from Colorado State University have developed a superhemophobic surface treatment for titanium that repels liquids including blood, plasma, and water. The result is a surface that completely repels any liquid with which it would come in contact and the body doesn't even recognize that it's there. https://futurism.com/weve-created-a-life-saving-blood-repellant-super-material/
