Robotic Surgery On a Beating Heart 54
An anonymous reader writes "Serious heart surgery usually involves stopping the organ and keeping the patient alive with a cardiopulmonary bypass machine. But this risks brain damage and requires a long recuperation. Scientists at Harvard University and Children's Hospital Boston have now developed a device that lets surgeons operate on a beating heart with a steady hand. The 'robotic' device uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a faulty valve as it moves. The approach should improve recovery times and give a surgeon instant feedback on the success of the procedure, the researchers say. Here's a (slightly gory) video of the device in action."

I had valve replacement surgery two months ago. While everything went extremely well (thank you Emory hospital), my wife would have appreciated not hearing the words "it's going well, they're stopping his heart now...".

Probably minimal. Even with total failure, the solution would be to pull the needle and switch to a standard valve replacement surgery. Once that happens, anything done by the machine can be reversed and damage repaired, if necessary. Of course, something more terrible could happen (I'll save the descriptions for a horror screenplay) but the more catastrophic potential complications are far more likely to be operator error than a problem with the software of the device.

Basically, airplanes can land just fine by themselves. It is vital that they are able to do so in no visibility situations.
