Clinical Trial Summary

This trial is designed to assess the safety and effectiveness of the ThrombX Retriever.

Description:

This trial is a clinical evaluation is to assess the safety and effectiveness of the ThrombX Retriever in the revascularization of the site of primary occlusion in patients presenting with acute ischemic stroke secondary to intracranial, large vessel, occlusive disease.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Successful reperfusion of the occluded target vessel with up to 3 passes of the ThrombX Retriever	Defined by a mTICI score >2b	Up to the end of theprocedure
Primary	Safety Endpoint	Symptomatic intracerebral hemorrhage (sICH) confirmed on imaging and other Serious Adverse Device Effects (SADE) within 24 hours post procedure. The sICH is defined as the presence of extravascular blood in the cranium associated with an increase in the NIHSS score of = 4 points or death.	24 hours
Secondary	Functional independence defined by modified Rankin Scale (mRS)	modified Ranking Scale is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke. The scale runs from 0-6, running from perfect health without symptoms to death.	90 Days
