A vascular device intended to be percutaneously implanted in the inferior vena cava (IVC) to prevent pulmonary embolism (PE); it can be retrieved before a threshold period or remain as a permanent implant after the period. It achieves its unconstrained diameter upon deployment in the IVC and imparts an outward radial force on the luminal surface of the vena cava to ensure proper positioning and stability. It is designed for blood clot capture while maintaining caval patency. It is made of metal alloys [e.g., stainless steel, titanium (Ti), nickel-titanium alloy (Nitinol)] and is available in various self-expanding designs (e.g., conical, basket). This is a single-use device.
