Histological measurement of clot analogs and comparison of 6Fr and 8Fr catheters in the in vitro model. (A) The histological composition of the three human clot analog phenotypes (RBC-rich, mixed, and fibrin/platelets-rich) used in the study was assessed and quantified using the MSB stain, (n=3 replicates for each clot phenotype). (B) Comparison of the first-pass complete ingestion of Millipede 088 (8Fr) versus 6Fr catheters in M1 and ICA occlusions. (C) Comparison of the first-pass and second-pass revascularization success rates of Millipede 088 (8Fr) versus 6Fr catheters in M1 (10 mm) occlusions. (D) Comparison of the first-pass and second-pass revascularization success rates of Millipede 088 (8Fr) versus 6Fr catheters in ICA (20 mm) occlusions. n=5 replicates in all in vitro tests. ICA, internal carotid artery; MSB, Martius Scarlet Blue; RBCs, red blood cells; WBCs, white blood cells.
