Pilot Study Evaluating the Safety of the Angel® Catheter in Critically Ill Patients at High Risk of Pulmonary Embolism, 2013 Society of Critical Care Medicine (SCCM) Meeting, January 2013

This prospective pilot interventional study was conducted from December 2011 to March 2012. Patients in the intensive care unit (ICU) were recruited for the study and were followed up for 30 days after device retrieval. All patients were at high risk of PE, but were not receiving medical thromboprophylaxis because of either increased risk of bleeding or ongoing bleeding.

Short and Medium Term Evaluation of the Angel® Catheter (Central Venous Catheter and Inferior Vena Cava Filter) for the Prevention of Pulmonary Embolism, 2012 International Symposium on Endovascular Therapy (ISET) Meeting, January 2012

During this animal study, the Angel® Catheter was inserted in 31 Ovine models. After insertion and verification of the position in the infrarenal IVC, the catheter was secured and left in position for 2 hours (10), 48 hours (6), 7 days (7) and 14 days (8). After this period, the functionality of the catheter as well as pathologic sections of the vena cava were assessed.

Short Term Evaluation of a Central Venous Catheter and Inferior Vena Cava (IVC) Filter (The Angel®Catheter) for Prevention of Pulmonary Embolism (PE), 2011 America College of Chest Physicians (ACCP) Meeting, October 2011

In this study, the Angel® Catheter was inserted in 3 female Willamatte Cross (Ovine animal model). After insertion and verification of the position in the infrarenal IVC, the catheter was secured and left in position for 14 days. After this period, the functionality of the device as well as pathologic sections of the vena cava were assessed.

In Vitro Placement and Effectiveness of the Angel® Vena Cava Filter Catheter, 2011 International Symposium on Endovascular Therapy (ISET) Meeting, January 2011

The study was conducted in a vena cava simulator with tubing diameters of 16mm, 19mm, 25mm and 30mm. Human blood has a mean density of 1.055 g/mL and a mean viscosity of 0.035 St at a mean temperature of 37C. Therefore, the vena cava simulator mimicked physiological conditions by using a blood analog aqueous solution, composed of 52% glycerin by weight with a density of 1.12g/ML and a viscosity of 0.032St that was circulated at 37 ± 2°C. This study focused on Filter Deployment and Retrieval, and Clot-Trapping Effectiveness compared to other retrievable IVC filters.
