Position matters
Toro 88 enables physicians to confidently reach further. Patients with large bore catheters located in the petrous segment or beyond have a significantly higher first-pass effect and shorter procedure times.*
Higher intracranial positioning of an 8F guide catheter improves efficacy of aspiration thrombectomy in large vessel occlusions.
Ischemic stroke occurs when blood flow to the brain is blocked by a clot, causing brain tissue damage. Quick intervention is critical to minimize disability and save lives.
#1 Cause of Disability
Stroke is the leading cause of long-term disability worldwide
795,000+ Annual Cases
