Conditions studied: Pulmonary Embolism Acute
In brief
This study is a prospective, single-arm, interventional, multicenter study to evaluate the safety and effectiveness of percutaneous mechanical thrombectomy using the Akura Thrombectomy System in subjects with acute pulmonary embolism (PE).

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- The patient is 18 years of age or older and deemed medically eligible for interventional procedure, per institutional guidelines and clinical judgement
- Clinical signs, symptoms and presentation consistent with acute PE
- PE symptom duration ≤ 14 days
- CTA evidence of proximal PE (filling defect in at least one main or lobar pulmonary artery)
- CTA evidence of RV/LV ratio of ≥ 0.9 (NOTE: Enrollment qualification assessment is based on the Investigator's interpretation of RV/LV ratio at baseline)
- Systolic BP ≥ 90 mmHg (initial SBP may be < 90 mmHg but ≥ 80 mmHg if the pressure recovers with volume resuscitation)
- Stable HR < 130 BPM prior to the procedure
You may not qualify if…
- Prior PE <180 days from index procedure
- Thrombolytic use within 30 days prior to baseline CTA
- Pulmonary hypertension with peak pulmonary arterial pressure (PAP) > 70 mmHg by right heart catheterization
- Vasopressor requirement after fluids to keep pressure at ≥ 90 mmHg
- FiO2 requirement > 40% or > 6 LPM (to keep oxygen saturation > 90%)
- Hematocrit < 28% (Note: hematocrit required within 6 hrs. of index procedure)
- Platelets < 100,000/μL
- eGFR <30 ml/min per 1.73 m2
- International normalized ratio (INR) > 3
- Major trauma injury severity score (ISS) > 15
- Presence of intracardiac lead in right ventricle or atrium placed ≤ 6 months of enrollment
- Cardiovascular or pulmonary surgery within the last 7 days
- Actively progressing cancer treated by chemotherapeutics
- Known bleeding diathesis or coagulation disorder
- Left bundle branch block
- History of severe or chronic pulmonary arterial hypertension
- History of chronic left heart disease with left ventricular ejection fraction ≤ 30%
- History of uncompensated heart failure.
- History of underlying lung disease that is oxygen dependent
- History of chest irradiation
- History of heparin-induced thrombocytopenia (HIT)
- Contraindication to systemic or therapeutic doses of anticoagulants
- Known anaphylactic reaction to radiographic contrast agents that cannot be pretreated
- Known residual iliac deep vein thrombosis (DVT), inferior vena cava (IVC) clot or clot in transit (right atrium and/or right ventricle)
- CTA imaging or other evidence that suggest, in the opinion of the investigator, the Subject is not appropriate for mechanical thrombectomy intervention (e.g. inability to navigate to target location, predominantly chronic clot or non-clot embolus)
