O-060 Evaluation of experimental acute ischemic stroke models for measuring stent retriever removal forces

ConclusionClot hematocrit did not influence SR removal forces, while model tortuosity positively correlated. Testing concluded that common AIS model materials underpredict the frictional forces that likely occur in-vivo by 2-4x. Additionally, it was determined that SR-artery frictional forces are much larger than clot-artery frictional forces and are the primary driver of overall removal force. The decreased forces between clots/SRs and experimental materials could explain the higher recanalization rates observed in in-vitro models.Abstract O-060 Figure 1Disclosures D. Poulos: None. O.
