College of DundeeDocs from Scotland and the US have accomplished what’s considered a world-first stroke process utilizing a robotic.
Prof Iris Grunwald, of the College of Dundee, carried out the distant thrombectomy – the elimination of blood clots after a stroke – on a human cadaver that had been donated to medical science.
The professor was at Ninewells Hospital in Dundee, whereas the physique she was working on whereas utilizing the machine was throughout town on the college.
Hours later, Ricardo Hanel – a neurosurgeon in Florida – used the expertise to hold out the primary transatlantic surgical procedure from his Jacksonville base on a human physique in Dundee over 4,000 miles (6,400km) away.
College of DundeeThe crew has referred to as it a possible “sport changer” if it turns into accepted to be used on sufferers.
The medics consider this expertise might rework stroke care, as a delay in accessing specialist therapy can have a direct impression on the probabilities of restoration.
Prof Grunwald stated: “It felt as if we had been witnessing the primary glimpse of the long run.
“The place beforehand this was considered science fiction, we demonstrated that each step of the process can already be finished.”
The College of Dundee is the worldwide coaching centre of the World Federation for Interventional Stroke Remedy, and is the one place within the UK the place medical doctors can function on cadavers with liquid which mimics human blood circulated within the vessels.
“This was the primary time that we might carry out the entire mechanical thrombectomy process in an actual human physique to point out that every one steps of the process are attainable,” stated Prof Grunwald.
Juliet Bouverie, the chief government of the Stroke Affiliation charity, informed BBC Information the transatlantic process was “a outstanding innovation”.
She added: “For too lengthy, individuals residing in distant and rural areas have been disadvantaged of entry to thrombectomy.
“Robotics like this might rebalance the inequity which exists in stroke therapy throughout the UK.”
College of DundeeWithin the experiment, fluid which mimics human blood was utilized in 4 completely different cadavers.
The themes, who donated their our bodies to science, died inside the previous three years and had been then embalmed.
Each the Dundee and Florida procedures had been carried out final month utilizing robotics from the Lithuanian agency Sentante.
Whereas there have been distant thrombectomies carried out earlier than on a silicon model, a 3D printed replica and on an animal, that is thought to have been the primary process on a human physique.
The crew now hope to participate in medical trials subsequent 12 months.
How does the expertise work?
An ischaemic stroke happens when an artery is blocked by a clot.
This cuts off blood and oxygen provide to the mind, and mind cells lose operate and die.
The perfect therapy is a thrombectomy, the place a specialist makes use of catheters and wires to take away the clot.
However what occurs when a affected person cannot get to a specialist who can do the process?
Prof Grunwald stated the experiment demonstrated a robotic could possibly be linked to the identical catheters and wires a surgeon would usually use, and a medic who’s with the affected person might merely connect the wires.
The surgeon, in one other location, might then maintain and transfer their very own wires, and the robotic then carries out precisely the identical actions in actual time on the affected person to hold out the thrombectomy.
The affected person could be in a hospital working room, whereas the physician might perform the process utilizing the Sentante machine from anyplace – even their very own dwelling.
Prof Grunwald and Ricardo Hanel might see stay X-rays of the physique within the experiments, and monitor progress in actual time, with the Dundee skilled saying it took solely took 20 minutes of coaching.
Tech giants Nvidia and Ericsson had been concerned within the venture to make sure the connectivity of the robotic.
Dr Hanel stated: “To function from the US to Scotland with a 120 millisecond lag – a blink of a watch – is really outstanding.”

SentanteThe way forward for stroke therapy
Prof Grunwald, who has gained an award from Innovate UK for her work and can also be the vice chairman of the World Federation for Interventional Stroke Remedy, stated there have been two important issues with a typical thrombectomy – a world scarcity of medical doctors who can do it, and therapy is determined by your location.
In Scotland, there are solely three locations sufferers can obtain the process – Dundee, Glasgow and Edinburgh. Should you do not stay there, you have to journey.
Prof Grunwald stated: “The therapy may be very time delicate.
“Each six minutes delay, you could have a 1% much less likelihood of getting a very good consequence.
“This expertise would now present a brand new means the place you are not relying on the place you reside – saving the dear minutes the place your mind is in any other case dying.”
Public Health Scotland said there have been 9,625 ischaemic strokes in Scotland final 12 months.
Solely 212 – or 2.2% of all sufferers – obtained a thrombectomy, whereas 1,045 individuals obtained medicine to burst the clots.
For the remainder of the UK, only 3.9% of all stroke patients obtained a thrombectomy within the 12 months to March 2024.
“It feels wonderful,” added Edvardas Satkauskas, the CEO of Sentante, chatting with BBC Information from the corporate’s base in Lithuania.
“Typically, the long run is means nearer than we expect.”
