Patent number: 7004955Abstract: 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.Type: GrantFiled: April 16, 2003Date of Patent: February 28, 2006Assignee: Endovascular Technologies, Inc.Inventors: Christopher T. Shen, Olin Palmer
