Abstract
Intravascular filter devices adapted for temporary or permanent insertion in a blood vessel are disclosed. An intravascular filter device may comprise a first set of filter legs configured to attach to a vessel wall, and a second set of shorter filter legs configured to attach at a different location to the vessel wall. Both sets of filter legs may include a proximal filtering portion and a distal centering portion, and can be configured to radially expand in an outward direction and with equal force when placed in the vessel. Moreover, the filter device may employ one or more features to ensure uniform clot capturability across the vessel.
