Fig. 6From: Gastric artery embolization: studying the effects of catheter type and injection method on microsphere distributions within a benchtop arterial modelObserved (green) and hypothesized (yellow) pre-injection arterial flow vectors: a before the introduction of a catheter; b with an end-hole catheter (negligible flow obstruction), c with a Surefire catheter with deployed tip (partial flow obstruction at tip), and d with an Endobar catheter with inflated balloon (complete flow obstruction at balloon).
