World’s First Transatlantic Thrombectomy Heralds New Era



The University of Dundee has bolstered its position as a global leader in stroke treatment and training by taking part in the world’s first robotic transatlantic thrombectomy.


The event came hours after Dundee’s Professor Iris Grunwald, Director of the Image Guided Therapy Research Facility (IGTRF), performed the first-ever remote thrombectomy on a human cadaver.


Using a cutting-edge robot developed by Lithuanian MedTech company Sentante, Professor Grunwald proved that a blood clot could be removed from the brain without a specialist being physically present when she performed the procedure from a remote site within the School of Medicine at Ninewells Hospital.


That was followed by the groundbreaking moment when Ricardo Hanel MD, PhD – in conjunction with Professor Grunwald – used Sentante’s device to perform the first transatlantic thrombectomy on a human cadaveric model located at the IGTRF from Baptist Medical Center in Jacksonville, Florida.

The Sentante platform uses standard guidewires and catheters connected to a device equipped with a high-resolution sensory system that captures the specialist's hand movements. These manipulations are replicated in real time by a robot at the patient's bedside.


Unlike joystick-controlled surgical robots, Sentante delivers authentic force feedback directly to the surgeon's fingertips – recreating the tactile experience of manual surgery. The procedure only necessitates a medical professional trained to gain arterial access before a specialist such as Professor Grunwald or Dr Hanel performs the thrombectomy remotely.


Professor Grunwald said,:

“As a neurointerventionist, it is remarkable to feel the same fine control and resistance through a robotic interface as during a live procedure. Sentante’s technology truly bridges the gap between operator and patient, no matter the distance. Sentante’s robotic platform redefines what is possible in endovascular treatment today. It is precision, safety and access to treatment - all in one innovation.”

Each year, there are about 15 million strokes worldwide. For the UK, the aggregate societal cost is estimated at £26 billion per year, including £8.6 billion for NHS and social care.


Thrombectomy is considered the most effective way to treat patients with stroke caused by a large, blocked brain vessel but, in many parts of the world, less than 1% of patients receive this life- and brain-saving treatment. In 2024 only 212 patients received a Thrombectomy across Scotland. This represents 2.2% of patients who had an ischemic stroke.


One of the major constraints to expanding thrombectomy services is the number of interventional neuroradiologists required to carry out the work.


“By the time patients reach a specialist centre, there’s often no brain left to save. Every six minutes delay in receiving treatment equates to a 1% lesser chance of a good outcome,” continued Professor Grunwald.

“For example, here in Dundee we're covering the north of Scotland – so a patient coming from Inverness or one of the islands would have a long distance to travel. The answer lies in expanding expertise locally through cross-specialty training, or by using robotic technology, such as Sentante, that lets experts operate remotely.”

Dr Hanel added, “Tele neurointervention will allow us to decrease the gap and further our reach to provide one of the most impactful procedures in humankind – the thrombectomy – to more people. To operate from the US to Scotland with a 120 millisecond (blink of an eye) lag is truly remarkable.”


The IGTRF is the official global training centre for the World Federation for Interventional Stroke Treatment, training doctors and teams from across the world. The facility offers a unique medical imaging environment that works in close collaboration with Dundee’s Centre for Anatomy and Human Identification (CAHID) to provide interventional training, medical device testing and research opportunities.


One of the University’s key strengths is the development of a perfused whole body human stroke model, which most closely approximates to ‘life-like’ patient simulation.


Edvardas Satkauskas, co-founder and CEO of Sentante, said:

“The human cadaveric models at Dundee are fantastic. This is the reason we have worked with them – this is probably the only site in the world that can do this type of research."

“For an ischaemic stroke, the difference between walking out of hospital and a lifetime of disability can be just two to three hours. Today, patients are often transported long distances to reach one of a limited number of thrombectomy centres. With Sentante, the specialist comes to the patient over a secure network and performs the entire procedure remotely – with the same tactile feel and control they have at the bedside.”


Sentante’s robotic platform is advancing through regulatory pathways for peripheral vascular interventions, with the FDA granting Breakthrough Device Designation for its stroke system. The Dundee collaboration marks the next milestone, showing how robotics can remove distance as a barrier to life-saving care.

There are few trees in the natural world as captivating as the magnolia. With their large, fragrant blooms and striking foliage, magnolias have long been admired for their beauty and resilience. These ancient plants, dating back millions of years, have a presence that is both regal and deeply evocative of the changing seasons. Whether found in manicured gardens or flourishing in the wild, their flowers—ranging from creamy whites and soft pinks to deep purples and even vibrant yellows—never fail to make an impression.


Magnolias belong to the Magnoliaceae family, a lineage that has existed since before bees evolved, relying instead on beetles for pollination. This ancient method of survival is just one of the remarkable aspects of these trees, which have continued to thrive in diverse climates across Asia, the Americas, and even parts of Europe. Some of the most well-known species include Magnolia grandiflora, with its glossy evergreen leaves and large, lemon-scented flowers, and Magnolia soulangeana, the beloved saucer magnolia that bursts into bloom in early spring, often before its leaves appear.


There is a certain magic in watching a magnolia tree come to life after winter. The buds, often covered in a soft, fuzzy coating, unfurl into petals that appear almost wax-like in their perfection. Their fragrance, sometimes citrusy, sometimes sweet and heady, drifts through gardens and parks, drawing admirers from near and far. These trees have long been symbols of dignity and perseverance, their enduring nature reflected in their ability to withstand extreme weather conditions and thrive in a variety of soils.


Beyond their ornamental appeal, magnolias have also been valued for their medicinal properties. Traditional Chinese medicine has long utilised magnolia bark for its anti-inflammatory and calming effects, while modern research continues to explore its potential health benefits. The tree’s wood, known for its strength and fine grain, has been used in furniture-making and construction, further cementing its role as both a functional and aesthetic treasure.


In literature and art, magnolias often serve as metaphors for beauty, strength, and renewal. Their brief yet spectacular flowering period reminds us of the fleeting nature of life’s most exquisite moments, while their deep roots and sturdy trunks speak of resilience and continuity. Whether growing in sprawling estates, tucked away in quiet urban courtyards, or lining the avenues of historic towns, magnolias bring a sense of grace and tranquillity to their surroundings.


As spring arrives and the first magnolia buds begin to open, their timeless elegance is once again on full display. These trees, with their prehistoric origins and poetic presence, continue to captivate generation after generation.


Whether admired for their history, their symbolism, or simply their stunning blooms, magnolias remain one of nature’s most enduring wonders.
