Doctors from Scotland and the United States have performed what is considered a pioneering stroke procedure using robotic technology.
The lead surgeon, working at a Scottish university, conducted the distant clot removal - the removal of circulatory obstructions following a cerebral event - on a medical specimen that had been donated to medical science.
The expert was working from a medical facility in the Scottish city, while the subject undergoing procedure with the system was separately situated at the university.
Subsequently, Ricardo Hanel from the US location used the technology to carry out the first transatlantic surgery from his American facility on a human body in the Scottish city over 4,000 miles away.
The team has described it as a potential "transformative advancement" if it gains clearance for use on patients.
The medics think this system could revolutionize stroke treatment, as a limited availability of specialist treatment can have a major influence on the healing potential.
"The experience was we were observing the initial vision of the coming era," commented the medical expert.
"While in the past this was considered science fiction, we showed that all stages of the surgery can now be performed."
The University of Dundee is the global training center of the World Federation for Interventional Stroke Treatment, and is the sole location in the United Kingdom where medical professionals can work with cadavers with biological fluid circulated in the blood pathways to mimic treatment on a live human.
"This represented the pioneering moment that we could execute the entire surgical process in a genuine medical subject to demonstrate that each stage of the operation are possible," explained Prof Grunwald.
A healthcare leader, the head of a stroke charity, described the long-distance operation as "a significant breakthrough".
"During many years, people living in isolated regions have been limited in obtaining to thrombectomy," she continued.
"Robotics like this could rebalance the inequity which persists in stroke treatment throughout Britain."
An blockage stroke happens when an artery is blocked by a clot.
This cuts off vascular flow to the brain, and neural cells cease working and deteriorate.
The best treatment is a surgical extraction, where a expert uses medical instruments to remove the clot.
But what transpires when a individual can't get to a expert who can perform the surgery?
Prof Grunwald explained the study showed a mechanical device could be attached to the same catheters and wires a surgeon would typically employ, and a medic who is present with the individual could simply attach the tools.
The specialist, in another location, could then operate and direct their individual tools, and the robot then executes precisely identical actions in immediate sequence on the subject to carry out the surgical procedure.
The subject would be in a treatment center, while the specialist could conduct the operation via the automated equipment from any location - even their personal residence.
The medical expert and the neurosurgeon could see live X-rays of the specimen in the studies, and observe results in live conditions, with the lead researcher stating it took just a brief period of instruction.
Technology companies leading tech firms were participated in the project to ensure the connectivity of the mechanical device.
"To conduct procedures from the US to the Scottish nation with a minimal delay - a moment - is truly remarkable," said the neurosurgeon.
The medical expert, who has won an award for her contributions and is also the executive member of the World Federation for Interventional Stroke Treatment, stated there were two main problems with a conventional clot removal - a worldwide deficiency of doctors who can do it, and treatment depends on your geographical position.
In the Scottish nation, there are just three locations individuals can receive the procedure - three major cities. If you reside elsewhere, you must travel.
"The procedure is highly dependent on timing," said Prof Grunwald.
"For every six minutes of waiting, you have a slightly decreased likelihood of having a positive result.
"This innovation would now deliver a innovative method where you're not depending on where you live - preserving the valuable minutes where your brain is otherwise dying."
