Merci
Inserted through the catheter, a tiny corkscrew-shaped device, called the MERCI, allows the neuroendovascular specialists to capture the clot and pull it free and away from the site of the blockage. This procedure can be used up to eight hours after the onset of stroke symptoms.
The Solitaire Flow Restoration device was approved by the FDA in 2012 for mechanical thrombectomy of proximal occlusion of intracranial arteries.
The system allows faster, safer, and more efficient thrombectomy than Merci or Penumbra systems 1).
The results of a study suggest that a tortuosity in M1 may be associated with unsuccessful recanalization using the Merci retrieval system, even when and adjunctive treatments are used, although this finding should be confirmed in a larger population 2).
