Pilot Study Evaluating the Safety of a Combined Central Venous Catheter and Inferior Vena Cava Filter in Critically Ill Patients at High Risk of Pulmonary Embolism

The objectives of this pilot trial were to assess the safety of a new device for pulmonary embolism (PE) prophylaxis. The device, the Angel Catheter, was placed in eight patients who were in the intensive care unit and were at high risk of PE. The device was inserted at the bedside without fluoroscopic guidance via a femoral venous approach. All eight devices were inserted and subsequently retrieved without complications (follow-up, 33–36 d). One filter trapped a large clot.
