  22. Known anaphylactic reaction to radiographic contrast agents that cannot be pretreated
  23. Imaging evidence or other evidence that suggests, in the opinion of the Investigator, the Subject is not appropriate for aspiration thrombectomy intervention such as the inability to navigate to target location, predominantly chronic clot or non-clot embolus
  24. Life expectancy of < 90 days, as determined by Investigator
  25. Female who is pregnant or nursing
  26. Current participation in another investigational drug or device treatment study that has not reached the primary endpoint or the Investigator feels would impact their ability to participate in this clinical trial
