Abstract
The present invention provides an intravascular filter for minimally invasive deployment into, and extraction from, a blood vessel. The invention comprises an inferior vena cava filter used to prevent migration of clots into the pulmonary artery wherein the filter has a novel architecture such that the filter can be extracted from the vessel without substantially damaging the vessel, even after prolonged periods of deployment.
