Objective:
Evaluate the safety and effectiveness of the FlowTriever System for treatment of PE in a real-world patient population.
Design
- Prospective, single-arm, multicenter registry: ~1,000 patients, up to 70 sites
- Follow-up at 48-hours & 30-days, 6 months
Primary Endpoint: MAE Composite through 48h
- Device-related mortality
- Major bleeding
- Intraprocedural device or procedure-related AEs, including clinical deterioration and device-related pulmonary vascular or cardiac injuries
Secondary Endpoints
- Impact on acute hemodynamics, procedural measures, 48h/30d all-cause mortality, and longer-term patient outcomes

Transforming the Lives of Patients with Venous Disease
Interim FLASH data demonstrates the ability of FlowTriever® to treat real-world PE patients with unmatched safety, clinically meaningful, on-table improvements, and sustained long-term benefits without the need for thrombolytic drugs or consequent ICU.
Safety
Enrolled intermediate-risk and high-risk PE patients with 0 deaths at 48 hours and only one death (0.4%) at 30 days (non-PE related)
- MAE = 1.4% (0 device-related deaths, 6 major bleeds (non-ICH), and 1 procedural-related AE (non device-related)
- No device-Related major adverse events
Effectiveness
Patients experienced immediate symptom improvement with significant changes in hemodynamics and vitals, as well as significant improvement in cardiac function and quality of life at 6 months
- Heart rate, PA pressure and cardiac index immediately improved compared to baseline
- Severe dyspnea, RV size, RV function and quality of life all significantly improved long-term
Resource Efficiencies
Minimal hospital resource footprint following FlowTriever intervention
- Median ICU Stay post-procedure of 0 days
- 30-day PE-related readmission rate of 1.3%
- 96.2% of patients treated without adjunctive therapies
