Evaluating the Safety and Efficacy of the AlphaVac Multipurpose Mechanical Aspiration (MMA) F1885 PE for Treatment of Acute Pulmonary Embolism

To evaluate the safety and effectiveness of percutaneous mechanical aspiration thrombectomy using the AlphaVac Multipurpose Mechanical Aspiration (MMA) F1885 PE in a prospective trial of patients with acute intermediate-risk pulmonary embolism (PE).

Inclusion Criteria:

• Signed and dated informed consent form.
• 18 years of age and older.
• Clinical signs and symptoms consistent with acute intermediate-risk pulmonary embolism for less than or equal to 14 days.
• Diagnosis of pulmonary embolism detected from computed tomography angiography (CTA).
• Right Ventricle to Left Ventricle (RV/LV) ratio of 0.9 or higher.
• Systolic blood pressure (SBP) of 90 mmHg or higher
• Heart rate of 130 beats per minute (BPM) or less prior to the procedure.
• Deemed medically eligible for interventional procedure(s) per institutional guidelines and/or clinical judgment.

Exclusion Criteria:

Excluded from the study if he/she meets any of the following exclusion criteria

• May be pregnant as determined by a positive pregnancy test or who are breastfeeding.
• Has any contraindication to systemic or therapeutic doses of heparin or anticoagulants.
• Has used thrombolytics (tPA) in the past 30 days of baseline CTA.
• Has pulmonary hypertension with peak pulmonary artery pressure (PAP) > 70 mmHg.
• Fraction of inspired oxygen (FiO2) requirement >40% or >6 liters per minute (LPM) to keep oxygen saturations >90%

• Known bleeding diathesis or coagulation disorder.
• Has had a cardiovascular or pulmonary surgery within the past 7 days of index procedure.
• History of severe or chronic pulmonary hypertension, uncompensated heart failure, chest irradiation, underlying lung disease that is oxygen dependent, Heparin-induced thrombocytopenia (HIT) and/or chronic left heart disease with left ventricular ejection fraction ≤ 30%.
• Known anaphylactic reaction to radiographic contrast agents that cannot be pretreated.
• Requires Vasopressor after fluids to keep pressure ≥ 90 mmHg.
• With left bundle branch block.
• Has intracardiac lead in the right ventricle or atrium.
• Evidence such as imaging or other that suggests the subject is not appropriate for this procedure.
• Has life expectancy < 90 days.
• Dependent on extracorporeal life support such as extracorporeal membrane oxygenation (ECMO).
• Participation in another investigational study
