====== 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

Radiographic Outcomes with Solitaire versus Merci/Penumbra Systems for Acute

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

with successful recanalization using the Merci retrieval system with or without
