A Journal of Stroke and Cerebrovascular Diseases paper showed Open-Motion can be tuned toward catching more large-clot strokes or toward fewer false alarms, to fit transport distances and hospital capabilities. An earlier two-centre study found it correctly flagged 79% of large-vessel occlusions and cleared 84% of patients without one.

## Key facts

- More than 75,000 Americans have large-vessel strokes each year
- Only 713 of 1,941 US stroke centres (37%) offer clot removal
- Lead researcher: Christopher Favilla, University of Pennsylvania
- Open-Motion 3.0 is research-use only and not FDA evaluated
