Experimental evaluation of stent retrievers mechanical properties and effectiveness

Conclusions
None of the tested devices were effective in removing white clots of large diameter (≥6 mm). Constant radial force during retrieval allows constant cohesion to the vessel wall and pressure over the clot; such features allow for a higher rate of clot removal.
