Abstract
The disclosure provides a hair pin IVC filter device and a method to retrieve said device from the vena cava. The device comprises a tubular backbone slidably disposed relative to a hub with a bore formed therethrough. A plurality of filter legs are each attached to the hub. Each filter leg has a first arcuate segment extending arcuately to a second arcuate segment. The first and second arcuate segments provide flexibility to the device when implanted for filtering in the vena cava. Upon retrieval, each filter leg may be converted from a hair pin position to a substantially straight position to remove the filter device from any endothelialized tissue.
