Needle Design Keeps You in the Cavity

A new needle design coming out of MIT could possibly save patients from potentially serious complications from over-excited needle pushers. The design consists of an S-shaped needle with a filament inside. When the needle is moving through solid tissue, the filament is buckled up inside ready to spring. The second the needle enters a hollow cavity the filament rapidly advances forward, which doubles as keeping the needle from moving further into the cavity in question as well as letting you know you’re in. The device has been successful so far in preliminary testing.
The needle design looks to revamp blood draws, epidurals, chest tubes and even trochar placement for laparoscopic surgery. Word is that the device could be available in 3-5 years following testing.
