New Clot-Busting device could offer quick relief for lung blood clots

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years * Clinical signs, symptoms, and presentation consistent with acute pulmonary embolism (PE) * PE symptom duration ≤ 14 days * Filling defect in at least one main or lobar pulmonary artery on CTA * Right ventricle / left ventricle (RV/LV) ratio ≥ 0.9 on CTA (Investigator's reading) * Systolic blood pressure ≥ 90 mmHg * Stable heart rate \< 130 BPM prior to the index procedure * Anatomy that, in the opinion of the interventionalist, allows safe passage of the eTrieve™ catheters * Written informed consent Exclusion Criteria: * Patients with a combined reason for their decompensation (e.g., a patient with both sepsis and PE) * PE within 3 months prior to screening assessment * Thrombolytic use within 30 days prior to baseline CTA * Pulmonary hypertension with peak systolic PAP \> 70 mmHg * Inotrope or vasopressor requirement after fluid administration to keep the systolic blood pressure ≥ 90 mmHg * Fraction of inspired Oxygen (FiO2) requirement \> 40% or supplemental oxygen \> 6 LPM to keep oxygen saturation \> 90% * Any of the following laboratory findings (within 6 hours prior to index procedure): 1. Hematocrit \< 28% 2. Platelets \< 100,000/µL 3. Serum creatinine \> 1.8 mg/dL 4. INR \> 3 * Major trauma Injury Severity Score (ISS) \> 15 within 14 days prior to screening assessment * Intracardiac lead in right ventricle, right atrium or coronary sinus, placed within 6 months prior to screening assessment * Known presence of intracardiac clot * Cardiovascular or pulmonary surgery within last 7 days * Active malignancy and / or on chemotherapy * Known bleeding diathesis or coagulation disorder * Left bundle branch block * History of severe or chronic pulmonary arterial hypertension * History of left ventricular ejection fraction ≤ 30% * History of decompensated heart failure * History of underlying oxygen dependent lung disease * History of chest irradiation * History of Heparin Induced Thrombocytopenia (HIT) * Any contraindication to systemic therapeutic doses of heparin or other anticoagulants * Known anaphylactic reaction to radiographic contrast agents that cannot be adequately pre-medicated * Known hypersensitivity or contraindication to procedural medications which cannot be adequately managed medically * Imaging evidence or other evidence that suggests, in the opinion of the investigator, the subject is not appropriate for mechanical thrombectomy intervention * Life expectancy of \< 90 days as determined by the investigator * Co-morbid condition(s) that, in the opinion of the investigator, could limit the patient's ability to participate in the study, including compliance with follow-up requirements, or that could impact the scientific integrity of the study * Female who is pregnant or nursing * Current participation in another investigational drug or device treatment study * Previous enrollment in the eTrieve™ II Study
