Brief summary

This study study is a prospective, single-arm, multicenter study to evaluate the safety and effectiveness of the Vertex Pulmonary Embolectomy System in participants presenting with clinical signs and symptoms of pulmonary embolism.

Detailed description

The study is a prospective, single-arm, multicenter study to evaluate the safety and effectiveness of the Vertex Pulmonary Embolectomy System in participants presenting with clinical signs and symptoms of acute pulmonary embolism. The Vertex Pulmonary Embolectomy System is intended for the non-surgical removal of emboli and thrombi from blood vessels as a means for treating pulmonary embolism.

Interventions

Use of Vertex Pulmonary Embolectomy System to treat pulmonary embolism.

Inclusion criteria

1. Age ≥ 18 years \< 80 years 2. Acute onset of symptoms ≤ 14 days consistent with the presence of pulmonary embolism. 3. CTA evidence (site determined) of proximal PE (filling defect in at least one main or interlobar pulmonary artery) 4. RV/LV ratio of \> 0.9 on CTA as assessed by investigator (site determined). 5. Systolic blood pressure ≥ 90 mmHg (initial SBP may be ≥ 80 mmHg if the pressure recovers to ≥ 90 mmHg with fluids) 6. Subject is willing and able to provide written informed consent prior to receiving any non-standard of care clinical investigation plan specific procedures 7. Subject is willing and able to comply with all clinical investigation plan required follow-up visits

Exclusion criteria

History of heparin-induced thrombocytopenia (HIT) 23. Contraindication to systemic or therapeutic doses of heparin or anticoagulants 24. Known anaphylactic reaction to radiographic contrast agents that cannot be pretreated 25. Imaging evidence or other evidence that suggests, in the opinion of the Investigator, the Subject is not appropriate for mechanical thrombectomy intervention 26. Life expectancy of \< 365 days, as determined by Investigator 27. Female who is pregnant or nursing 28. Current participation in another investigational drug or device treatment study 29. Inability to lay flat for procedure 30. Known presence of right-to-left cardiac shunt 31. History of Hemorrhagic or Ischemic Stroke, including Transient Ischemic Attack, within last 90 days 32.

Primary

MeasureTime frameDescription
Change in Right Ventricle/Left Ventricle (RV/LV) RatioFrom baseline to 48 hours or dischargeThe RV/LV diameter ratio is defined as the ratio of the maximal right ventricle (RV) to left ventricle (LV) diameters measured on computed tomography (CT) pulmonary angiography images. Measurements are performed by an independent core laboratory using standardized axial CT images, with ventricular diameters measured at the widest point of each ventricle. Change in RV/LV ratio is calculated for each participant as the difference between the value obtained at baseline (pre-procedure) and the value obtained at 48 hours post-procedure or at hospital discharge, whichever occurs first. A reduction in RV/LV ratio indicates improvement in right ventricular dilatation.
Major Adverse Events (MAEs)Within 48 hours of procedureA composite of: Device-related death within 48 hours Major bleeding within 48 hours Device-related AEs within 48 hours, including: * Clinical deterioration * Pulmonary vascular injury * Cardiac injury
