The physical and psychological impact of stroke can be devastating both for patients and their loved ones. Paralysis, impaired speech, loss of muscle control and memory, not to mention the emotional distress, are just a few of the potential consequences of a condition that affects more people every year. Stroke may impact one in four adults in their lifetime, according to The World Stroke Organization, and it is one of the leading causes of death and disability across the world.

A critical factor in successful treatment is time. Indeed, a common refrain among doctors is “time is brain” because almost two million neurons die every minute when blood flow is blocked. When a stroke happens, time is never on the patient’s side, but sadly, there is a distinct lack of specialist endovascular care in many parts of the world.

Without rapid treatment, 77% of those affected will suffer a large vessel occlusion stroke, resulting in death or severe disability, according to many studies including those by the Safe Implementation of Treatments in Stroke (SITS) and cited by the European Stroke Organisation. Yet, as noted by the global campaign Mission Thrombectomy launched by the Society of Vascular and Interventional Neurology (SVIN), almost 80% of hospitals equipped to perform the thrombectomy procedure required to remove a blood clot and restore normal blood flow are in just six countries: the US, UK, Brazil, France, Germany, and Australia.

If a surgeon with the necessary skills and experience is not close at hand, effective treatment for ischemic stroke is unlikely. Even in a country with trained neurosurgeons, those skills are still concentrated in specialist centres, so patients often face long and arduous journeys, under intense time pressure. Now, XCath’s Iris system, which is the only endovascular robotic system in development to achieve local or telerobotic intracranial treatment, is a step closer toward melting the geographical barriers that separate patients from specialist expertise.

This year, World Stroke Day is witness to a game-changing moment in history, as the world can witness the results of Operation Robo Angel, a stroke symptom awareness campaign and clinical investigation in Panama that led to the world’s first telerobotic neurosurgery.

New horizons

The result of years of hard work and dedication by a team of engineers and more than 60 physicians across five hospitals, Operation Robo Angel has conclusively demonstrated that telerobotic systems can deliver the control, accuracy and submillimetric precision to operate on fragile structures within the brain, even when the surgeon is not located in the same hospital or even the same city.

Using the Iris system, a remote robotic mechanical thrombectomy on a stroke patient has been performed for the first time. Renowned neurointerventional surgeon Dr Vitor Mendes Pereira operated from Santiago, Panama, on a patient more than 200km away in Panama City. With no perceptible latency, the system allowed Dr Pereira to precisely navigate intracranial blood vessels to successfully remove the clot on the first pass and fully restore blood flow to the brain.

“The work XCath has done with the Iris system is a giant step toward broadening access to mechanical thrombectomy for patients around the world. It is a highlight of my career to be involved in this historic achievement,” said Pereira after the procedure.

“The true legacy of this moment will be measured in the millions of lives that could be saved each year as stroke treatment reaches patients who today have no access to it,” said XCath CEO Eduardo Fonseca.

Redefining the future

Pereira himself is convinced that telerobotic systems can enhance a surgeon’s performance and greatly improve the safety of remote intracranial procedures. For patients across the world, this is a landmark moment in neurointervention and its success opens the door to more applications.

On 29 October 2026, to coincide with World Stroke Day, XCath released a documentary that takes a behind-the-scenes look at Operation Robo Angel. Hear from the team through their first-hand accounts of preparing for and performing this world-first procedure. Watch as a patient near death achieves a full recovery and hear as he and his family explain the impact on their lives of this groundbreaking innovation.

From this day onwards, the world’s understanding of stroke symptoms and access to surgical expertise could take a huge step forward.
