Patent ID: 8795351

Claim:
An embolic filter, comprising: a) a head having a proximal end and a distal end; b) a plurality of appendages extending distally from the head distal end including a plurality of arms, a first plurality of legs that are longer than the arms, the first plurality of legs including a plurality of bent legs, wherein each bent leg has a leg distal end providing a curved anchor with a curved portion, said curved anchor configured to engage an inner wall of a vein and prevent the embolic filter from migrating in a cranial direction, each bent leg having a bend that is positioned in between the leg curved anchor and the head, so that the curved anchor is not the location of the bend; c) a second plurality of legs that are longer than the arms and including a plurality of straight legs extending from the head, wherein each straight leg has a distal end with a caudal anchor that is configured to engage an inner wall of a vein to prevent the embolic filter from migrating in a caudal direction; and d) wherein the curved anchor of the bent legs is of a different configuration as compared to the caudal anchor of the straight legs.
