Brief summary
The study is designed to evaluate the short-term and long-term clinical performance and safety of the Symphony and Prodigy thrombectomy systems used in endovascular procedures across the peripheral or pulmonary vasculature.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Peripheral Arterial Cohort | 30 days | Freedom from major (above-ankle) unanticipated amputation of the index limb |
| Peripheral Venous Cohort | 30 days | Treated limb improvement at 30 days, defined as no unplanned intervention for breakthrough re-thrombosis and improvement in Villalta score relative to baseline. |
| Pulmonary Embolism (PE) Cohort | 30 Days | Normal right ventricular function at 30 days follow-up, defined as tricuspid annular plane systolic excursion (TAPSE) \>1.7cm , measured on transthoracic echocardiography (TTE) and independently adjudicated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Peripheral Arterial Cohort | 90 Days | Freedom from major (above-ankle) amputation of the index limb |
| Peripheral Venous Cohort | Intraprocedural | Technical success defined as complete or near complete (\>75%) reduction in Marder score from baseline to immediately after the use of the device and prior to any use of adjunctive device, as independently adjudicated |
| Pulmonary Embolism Cohort | Intraprocedural | Change in pulmonary artery pressure |
