Imagine a future where life-saving stroke treatment is available, no matter where you live. This future may soon be a reality, thanks to innovative robotic technology poised to revolutionize healthcare in remote areas.
St. Michael's Hospital in Toronto has successfully used a robot to perform 10 brain angiograms, a crucial step toward providing critical stroke care to patients in Northern Ontario. The goal? To bring this life-saving technology to the Sault Area Hospital in Sault Ste. Marie, Ontario, potentially as early as late next year or in early 2027.
But how does it work? A brain angiogram is a minimally invasive procedure where doctors insert a catheter into the femoral artery, guiding it to the brain to visualize blood vessels using X-ray imaging. Traditionally, a doctor is physically present, but this new technology allows a neurosurgeon to control a robot remotely, maneuvering the catheter with precision.
Dr. Vitor Mendes Pereira, head of St. Michael's neurovascular program, has been at the forefront of this innovation. He successfully performed angiograms, initially from across the room, then from another room, and finally from a hospital 6 kilometers away. The key? An incredibly fast fiber optic internet connection. Dr. Pereira noted that the experience was virtually identical, regardless of the distance.
The next ambitious step is to extend this distance to over 600 kilometers – the distance between Toronto and Sault Ste. Marie. After more diagnostic angiograms, the team will seek approval to conduct clinical trials, using the robot to perform endovascular thrombectomies (EVTs) on stroke patients. This procedure involves using a stent to remove blood clots, restoring blood flow to the brain.
Currently, stroke patients in Sault Ste. Marie must be transported to Sudbury, Ontario, for EVT treatment, a journey that can take up to 3.5 hours. Every delay means more brain cells die, increasing the risk of disability or death. Dr. Laura Stone, medical director of the Sault Area Hospital's emergency department, emphasizes the critical need for faster treatment: "Time is brain."
But here's where it gets controversial... If the Sault Area Hospital adopts this robotic technology, Dr. Pereira in Toronto could remotely guide the catheter and stent, offering immediate treatment. The St. Michael's team, led by Nicole Cancelliere, will train local staff on how to operate the robot.
Dr. Michael Kutryk, an interventional cardiologist and researcher, believes this technology can be life-changing. He estimates that it could be the difference between paralysis and recovery. The robot-assisted EVTs are expected to be operational in Sault Area Hospital by late next year or early 2027.
One of the main concerns is the reliability of the internet connection. However, the system is rigorously tested, with a backup plan in place. If any issues arise, the procedure can be stopped, and standard stroke care protocols will be followed.
And this is the part most people miss... It's not practical for the Sault hospital to have a neurovascular specialist on standby, given the relatively low number of patients needing EVTs annually (12-15). However, for those patients, this technology will be groundbreaking, significantly speeding up access to life-saving treatment. The St. Michael's team hopes to extend this technology to other remote areas.
Dr. Kutryk envisions this technology becoming a reality in hospitals worldwide soon, with the robot developed by Remedy Robotics, a company specializing in cardiovascular interventions.
