Sound wave neurosurgery

The procedure has been used before to remove uterine fibroids (or small, benign tumors in the uterus), and looks like a promising candidate to eliminate tumors from breasts and, hopefully, the brain. The biggest challenge when tackling the brain is getting the ultrasonic beams through the skull with any intensity, but that's handled by a head harness developed by InSightec, which is equipped with 1,000 ultrasound transducers and even built-in cooling to keep the skull from overheating.

Surgical Robot

After making a small incision, the robot compensates for the natural shake and movement of the organ caused by heartbeats so that surgery can proceed as if the organ is still. That little trick could enable minimally invasive, endoscopic heart surgeries in the future.
