Abstract

Vascular filtering devices and methods for their use are disclosed. In some embodiments, the vascular filtering devices include an elongate member having an unsupported membrane bag portion attached thereto. The membrane may be porous in some examples. Multiple elongate extensions may also extend from the membrane, and may extend along the elongate member, such as to a proximal region of the elongate member. The unsupported membrane bag portion may be configured to inflate or otherwise radially expand away from the elongate member as a result of blood flowing through the vessel within which the vascular filtering device is positioned.
