Acute ischaemic stroke cases are expected to rise from around seven million in 2025 to almost ten million by 2035. Efficient treatment is vital because delays in diagnosis or intervention can lead to irreversible brain damage or loss of life.
Neurovascular thrombectomy is used to mechanically remove a blood clot from blood vessels in the brain. It is an established and effective intervention for large vessel occlusions (LVO), often applied when pharmaceuticals cannot be administered or fail. Thrombectomy procedures once reserved for LVO are now increasingly being used to treat medium vessel occlusions (MVO), and this evolution in clinical practice is leading to changes in device design, shifts in pricing and improvements in treatment access. For an in-depth market analysis, GlobalData’s Neurovascular Thrombectomy Devices report offers epidemiological and device usage forecasts through to 2036.

Hospitals and clinicians operate under tight deadlines to perform diagnostics and intervene in stroke cases because treatment windows are narrow. This has resulted in strict eligibility criteria that help to improve predictability of outcomes for stroke procedures, but it has also limited access. Evidence is now growing that thrombectomy for MVO delivers benefit even under challenging conditions. Clinical studies are showing positive functional outcomes for smaller vessel cases, and as a result, more medical centres are expanding eligibility. This transition means that life-saving treatment will reach more patients.
Data from the US clearly illustrates the transformation. Between 2020 and 2025, intervention rates for LVO rose from 24% to 29% while MVO procedures jumped from 7% to 19%. This reflects the growing clinician confidence with MVO treatment. Similar trends are now appearing in other countries, indicating that thrombectomy procedures will increasingly involve smaller vessels, and procedures once considered complex or risky may become routine.
Device design is adapting to this new intervention landscape. Aspiration catheters — especially smaller-diameter models designed for MVO — are gaining traction. In the US, usage of aspiration catheters climbed from 46% of thrombectomy interventions in 2020 to 72% in 2025. These devices offer simpler access and shorter procedure times, and lower risk in complex anatomies. At the same time, aspiration catheters often cost less than half that of stent retrievers. That cost advantage helps regions with constrained reimbursement adopt newer treatment options. However, while catheters are more affordable today, improvements in design, bundled device offerings and supply-chain pressures suggest prices may rise and could surpass those of stent retrievers after 2035.
GlobalData forecasts that the thrombectomy devices market will grow significantly, from $1.2 billion in 2025 to $5.0 billion by 2035. The proportion of that value attributed to aspiration catheters is expected to surge from 58% in 2025 to 87% in 2035. This reflects not only rising procedure numbers but also higher average selling prices, particularly for devices built to treat smaller vessels and accommodate more complex anatomy. The evolving thrombectomy market depends on the increasing incidence of stroke, broader procedural eligibility and devices that balance anatomical demands with cost efficiency. Together these forces are transforming where innovation, access, and revenue intersect.
