Robots to the Rescue! King's Leads Global Push for Safer Stroke Tech

A groundbreaking global push to standardise robotics for stroke treatment could bring life-saving care to thousands of victims. King’s College London is leading the charge, setting vital new rules for tech that could revolutionise crucial brain clot removal.

Why Standardisation Matters

Until now, there was no agreed framework for building, testing, or evaluating robotic systems for mechanical thrombectomy (MT). This complex, life-saving procedure removes blood clots from the brain. It needs specialist expertise and must be done quickly. However, access is often limited.

Robotic surgical systems could expand access by letting specialists perform procedures remotely. But progress has been slowed by a lack of standardisation across studies.

“In 2023, we carried out a systematic review of endovascular robotics and autonomy,” Harry Robertshaw, a PhD student at King's, explained. “We found that although several studies existed, they were all testing different tasks, using different models and measuring different outcomes. This made it impossible to compare results or identify the most effective approaches.”

The Breakthrough Standards

To fix this, an international group of experts came together. They included specialists in neuroradiology, robotics, data science, health economics, and patient advocacy. The resulting position statement, published in the Journal of the American Heart Association (JAHA), defines new standards. These put patient safety first.

Harry Robertshaw added: "By bringing together experts from clinical practice, academia, industry and patient representatives, we have defined the first consensus standards for robotics and AI in thrombectomy navigation. This will help to move the technology forward as its integration with clinical practice moves closer to reality."

Patient perspectives were key in creating these guidelines. Input from groups like the Stroke Association ensured safety and real-world impact are central.

The Future of Stroke Treatment

While AI-assisted robotic MT isn't ready for routine clinical use, its future looks promising. The speed of innovation in both robotics and AI suggests transformative advances are coming soon.

Dr Thomas Booth, a senior author and King’s College London expert, commented: “Our work lays the foundation for that future by defining clear standards to ensure that global development and validation are well understood.”

The King's team recently showed that AI can autonomously perform MT navigation in a lab. These new frameworks will guide its development and eventual clinical trials.

Dr Booth added: "By establishing practical, consensus-driven recommendations, we are helping to ensure that when these technologies do reach patients, they do so safely, responsibly and with meaningful clinical benefit."
