Groups/Cohorts Assigned Interventions
Acute Ischemic Stroke patients
Patients presenting with signs and symptoms consistent with a diagnosis of Acute Ischemic Stroke, who are treated with the Merci Retrieval System during a Mechanical Thrombectomy procedure.
Procedure: Mechanical Thrombectomy
Thrombectomy performed with the Merci Retriever in the setting of acute ischemic stroke.
Other Name: Merci Retrieval System

Detailed Description:

The Merci Registry is a prospective multicenter registry with up to 3000 patients enrolled at a maximum of 100 sites.

The registry requires use (at least one pass in the intracranial vasculature) of any Merci Retriever device (X Series, L Series, V Series) in the setting of acute ischemic stroke due to large vessel intracranial occlusion.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
All patients with ischemic stroke treated with a Merci Retriever either alone or in combination with adjunctive therapies such as lytics will be included in the Registry.

Inclusion Criteria:

  • Patient with ischemic stroke is treated with a Merci Retriever that is indicated for thrombus removal in ischemic stroke. "Treated" is defined as being when a Merci Retriever is deployed in the neurovasculature of a patient with an ischemic stroke
  • Patient/patient's surrogate provides informed consent and is willing to comply with the protocol requirements and complete required clinical evaluations, or in the absence of informed consent, an IRB/EC approved waiver of consent and executed data use agreement are in place

Exclusion Criteria:

-There are no exclusion criteria for this protocol
