Arm Intervention/treatment
Single Arm
Single Arm - Use of Indigo Aspiration System (mechanical thrombectomy) to treat pulmonary embolism
Device: Indigo Aspiration System
use of mechanical thrombectomy to treat pulmonary embolism

Primary Outcome Measures :
  1. Right Ventricle/Left Ventricle (RV:LV) Ratio [ Time Frame: from baseline to 48 hours ]
    Change in RV/LV ratio per CTA

  2. Major Adverse Event Rate [ Time Frame: within 48 hours ]
    A composite of: device-related death, major bleeding, device-related SAEs (a composite of clinical deterioration, pulmonary vascular injury, cardiac injury)

Secondary Outcome Measures :
  1. Device-related Death Rate [ Time Frame: within 48 hours ]
  2. Major Bleeding Rate [ Time Frame: within 48 hours ]
  3. Clinical Deterioration Rate [ Time Frame: within 48 hours ]
  4. Pulmonary Vascular Injury Rate [ Time Frame: within 48 hours ]
  5. Cardiac Injury Rate [ Time Frame: within 48 hours ]
  6. Any-cause Mortality [ Time Frame: within 30 days ]
  7. Device-related SAE Rate [ Time Frame: within 30 days ]
  8. Symptomatic PE Recurrence Rate [ Time Frame: within 30 days ]
