This is the world's first trans-oceanic human operation, and has been reported in this week's issue of Nature.
The operation lasted under an hour. The control console was linked to the robots via a high-speed optical-fiber network, relaying information through dedicated connections.
The telesurgery technique was first used to remove pigs' gall bladders.
Two surgeons in Strasbourg set up the robotic system, which could be inactivated if necessary during the procedure.

In New York, another two surgeons directed the robots, while a third monitored the video link.
Data travelling between the two locations made a round-trip of over 14,000 kilometers.
Due to the time taken for the transfer and video-coding of data, the surgeons' movements appeared on their screens with a delay of around 155 milliseconds. This beat the estimated safe lag time of 330 ms.
This improved technology should remove geographical constraints on specialized surgery, as well as improve surgical training, say the researchers.
