When a stroke strikes, the clock starts instantly. A clot blocks a vessel in the brain, starving it of blood, and every minute that passes can mean the difference between walking out of hospital and a lifetime of paralysis. The procedure that can reverse that fate — mechanical thrombectomy, where doctors thread a hair-thin device through an artery to grab the clot and pull it out — has existed for years. But in India, the devices themselves were almost entirely imported, priced far beyond the reach of most patients. Mysuru-based S3V Vascular Technologies was built to change exactly that.
Founded in 2011 and incubated at the Indian School of Business in Hyderabad, S3V Vascular Technologies designs and manufactures advanced vascular and neuro devices in India. Its flagship achievement is a complete, indigenous mechanical thrombectomy kit for acute ischemic stroke — the company says it is the first Indian company to design and manufacture the full suite of neuro-intervention devices at home, rather than assembling imported parts.
A kit that pulls clots out of the brain
The kit works like a precision rescue mission inside the body’s own plumbing. The company says its Neuro Clot Retriever — a stent-like mesh — is guided to the clot, opens around it and draws it out, while its Neuro Aspiration Catheter can suction the clot away and its Neuro Microcatheter navigates the brain’s delicate vessels to deliver them. Together with guidewires, the four device families form one integrated system for large vessel occlusion, the most severe kind of ischemic stroke.
The engineering is genuinely homegrown. The company says it has filed patents for critical innovations including its clot retriever head design and a braid-over-coil structure for its aspiration catheter — the kind of fine, materials-level detail that decides whether a device can travel safely through twisting brain arteries and still grip a clot firmly.
India’s first neuro-intervention plant
In May 2025, the Technology Development Board (TDB) under the Department of Science and Technology extended financial support to S3V for what it calls India’s first neuro-intervention integrated manufacturing plant for stroke treatment. The state-of-the-art upstream integrated facility is coming up at the Medical Devices Park in Oragadam, Sriperumbudur, near Chennai — and the word “upstream” matters. The company says it is building the supply chain itself, from raw materials to finished devices, so that India does not simply swap imported devices for imported components.

The same month, the company says it received CDSCO approval to manufacture Class C and Class D neuro and spine devices — among the most stringently regulated categories in medical technology. The company is also pursuing CE marking and US FDA approval, with export markets across Asia, Latin America, Europe and North America in its sights.
Cutting the cost of a second chance
The human stakes are enormous. The company says around 20 lakh brain strokes take place in India every year, yet only a fraction of patients have ever reached an interventional procedure — and the company hopes its devices can help that number rise to at least 2.5 lakh procedures a year within a decade. The company says its low-cost brain-clot removal kits bring treatment costs down from around ₹10 lakh to around ₹1 lakh, and it intends to integrate its stroke-care devices with Ayushman Bharat so that the treatment reaches patients through government-supported insurance too.
To make sure the devices are used well, the company says it will work with hospitals across India on simulator-based training programmes, aimed especially at young interventionalists in Tier-II cities where stroke incidence remains high. A device is only as good as the hands that guide it — and S3V is building those hands too.
Beyond the brain: stents, cages and catheters
Stroke care is the headline, but S3V’s bench runs wider. Its portfolio includes the 3V Vajra, an expandable titanium spinal cage — the company says it is the first company globally licensed for an expandable titanium intervertebral body fusion cage — alongside the 3V Astra aspiration catheter, 3V Neil biodegradable drug-eluting stents, 3V Agile oesophageal stents and 3V Paulo balloon dilatation catheter. Its integrated Neuro Kit for brain-clot removal is lined up from Q4 FY26.
Behind the company are founder and managing director Dr N. G. Vijaya Gopal and founder and head of medical devices N. G. Badari Narayan, with backing from investors including A. M. Naik, Madhusudan Kela and Utpal Sheth. From a Mysuru workshop to a Chennai medical-devices park, S3V is building the same thing in every product: the chance for an Indian patient, in an Indian hospital, to walk back from a stroke — with devices made in India.
