Restores Blood Flow. It has been demonstrated that the timely restoration of blood flow in ischemic stroke patients may potentially minimize and possibly reverse injury to the brain. In our most recent trial, the Multi MERCI trial, the Merci Retrieval System was effective in restoring blood flow in large vessel ischemic stroke patients 54.9% of the time. Furthermore, upon the addition of adjunctive therapy, primarily an injection of a clot dissolving drug into the obstructed vessel, our Multi MERCI trial demonstrated successful restoration of blood flow 68.3% of the time
