- Robotic Thread – MIT engineers developed robotic thread that can be steered by magnet to pass through blood vessels in brain
- Material Components – Made of nickel-titanium alloy at core, coated with rubbery paste or ink and hydrogel, enabling smoother movements and biocompatibility
- Safer Procedure – Does not require manually inserting wire coated in polymer through blood vessels, which can cause damage if wire gets stuck, and exposing doctors to radiation by using fluoroscopes, device that image vessels through X-rays
- Remote Operations – Enables surgeons to perform operations, such as delivering drugs or removing blood clots in vessels, to cure strokes and aneurysms outside of operating room or from remote location using joystick
- Demonstration – Showed robotic thread going through silicon replica of brain's blood vessels, and passing through set of small rings as if moving through eye of needle
- Next Steps – Plans to incorporate existing magnetic technologies and test robotic thread in vivo or inside body of living organism
