Figure 18.

A) Schematic illustration of STB fabrication. STB is extruded from the catheter tip. B) Storage moduli (G′) of 6% (w/v) STBs after repeated cycles of low and high strain. C) A representative injection force curve to deliver STB through the catheter. Laser Doppler microperfusion imaging in mouse showing D) hindlimb perfusion before STB injection and E) no perfusion in STB injected limb. F) Coronal CT study confirmed no pulmonary embolism occurred in porcine model during 24 days after STB embolization. G) Gross evaluation at 24 days shows STB (arrow) occluding the vein. H) Percentage of vessel remodeling (replacement of STB with connective tissue) over time.
