1. A filter device, comprising:
- an elongate member having a first end and a second end, the second end extending exterior of the vasculature;
a body including a first section defining a first end portion, a second section defining a mid-portion, a third section defining a second end portion, the first section, the second section and the third section form a conically tapering filter, the body includes an open first end and a substantially closed second end;
the body having a longitudinal axis defined by a sidewall, the body being attached to the second end of the elongate member, the elongate member extending from the open first end in a parallel relationship with the longitudinal axis; and
the mid-portion further comprising three ring members adjacently configured end to end, each ring member having a plurality of first members in an alternating V-pattern to form sixteen apices defining each a ring proximal end and a ring distal end.

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.
