The AngelTM Catheter is a truly retrievable IVC filter that is permanently attached to a multi-lumen central venous access catheter.  It is intended for use in critically ill patients with VTE disease who are at increased risk of PE but for whom anticoagulation therapy is temporarily contraindicated.

The design of the Angel™ Catheter allows for easy insertion and access to the central venous system for administering medications, fluids, or blood products; blood sampling; and monitoring of central venous pressure.

The Angel™ Catheter is intended to be used during the critical time period in which anticoagulation therapy poses a high risk of complications, including major bleeding and death, and in which patients are at highest risk of VTE.  The filter can be easily removed when the central line is removed, once the danger of VTE has been resolved.

The Angel™ Catheter was invented by Luis F. Angel, MD, in response to the crucial problem of PE in critically ill patients.   This device takes advantage of a commonly used medical procedure, the placement of a central line, and allows for the placement of a truly temporary IVC filter as a means of PE prophylaxis in critically ill patients.  These patients are at the highest risk for complications with anticoagulation therapy and are frequently too sick to be moved outside the ICU for placement of an IVC filter.  Therefore, the Angel™ Catheter will allow for substantially improved PE prophylaxis and the potential for a worldwide reduction in the rates of PE-related mortality and morbidity.

BiO2 Medical has been working with Rosenbaum & Silvert, P.C., an intellectual property firm, to vigorously pursue and obtain patent protection for BiO2 Medical’s entire technology portfolio, including the designs and concepts of the Angel™ Catheter.
