Just last year, we showed you the concept i-Snake medical robot, and now a different team actually has a similar device for real: the CardioArm. This little robo-tentacle is being developed partly at Carnegie Mellon University, and is apparently the most flexible endoscope ever that follows its own camera-head in a snake-like way through your innards. Since it enters the body through a single incision, it's much less traumatic for the patient: minimally invasive surgery is clearly the way ahead.
Kinja is in read-only mode. We are working to restore service.
