Detailed Description

The purpose of this study is to demonstrate the safety and performance of the MIVI Neuroscience, Inc. CE Marked Q Aspiration Catheter for use in the removal of fresh, soft emboli and thrombi in the neurovascular system during acute ischemic stroke. The study is an observational study collecting Q Aspiration Catheter use that will enroll a maximum of 50 subjects at a maximum of 5 sites in Spain. Subjects data will be collected through hospitalization with a 3 months post-procedure study visit. This study is designed for observational data to be collected and reported.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Successful Revascularization Rate
Time Frame: intra-procedural
Defined as final modified Thrombolysis In Cerebral Infarction scale (mTICI 2b-3) flow in the target vessel
intra-procedural
Symptomatic Intracranial Haemorrhage Rate
Time Frame: 24 hours post procedure
Defined as the symptomatic intracranial haemorrhage as detected by CT/MRI with an NIHSS change of >/= 4 points
24 hours post procedure

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Successful Revascularization Rate Using the Q Aspiration Catheter as the Only Thrombectomy Device
Time Frame: intra-procedural
Defined as mTICI 2b-3 flow in the target vessel post-treatment with the Q Catheter (first line therapy)
intra-procedural
Rate of Embolization to a New Neurovascular Territory (ENT)
Time Frame: intra-procedural
As measured by independent Angiographic Core Lab
intra-procedural
Good Functional Outcome Measured by Modified Rankin Scale Score of 0-2
Time Frame: 90 days
The Modified Rankin Scale (mRS) measures neurological disability or dependence for stroke patients on a scale of 0 (no symptoms) to 6 (deceased).
90 days
Mortality Rate
Time Frame: 90 days
Rate of all cause mortality
90 days
