  • Patent number: 7004955
    Abstract: An intravascular filter device for use in capturing debris which may occur as a result of an intravascular procedure. The filter device includes a proximal section, a distal section and a mid-section. The mid-section includes three rings configured in a sixteen apices alternating V-pattern. The filter device specifically embodies structure that provides enhanced radial opening and angular resistance to collapse in its expanded state. While, in its compressed state the filter device provides an extremely small compressed profile giving it the desired ability to be delivered into very small vessels of the human vasculature.
