Catheter-related particle flow-dynamics. Composite figure of the fluorescent microsphere administrations with the SMC (a) and ARC (b) Images of fluorescent microsphere administrations were created by overlaying frames from a representative part of the experiment 3 video (Additional file 1: Movie S1), to show the typical catheter-related particle flow pattern. The background of images (a) and (b) was edited in Adobe Photoshop to emphasize an area of interest. a Off-centered SMC position, laminar outflow pattern and absence of microsphere flow towards the LHA. b Centro-luminal ARC position, turbulent outflow pattern (note the eddy current adjacent to the ARC tip) and more homogenous microsphere distribution over the LHA and RHA
