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.
Claims30
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.
A medical device for treating an interior of a patient, comprising:
- a body, the body including a first portion having first and second ends, a mid-portion having a ring member, the ring member having a first and second end, the first end of the ring member joined the second end of the first portion and a second portion having a first and second end, the first end of the body second portion with the second end of the ring member, the second end of the body second portion defining a closed terminal end of the body;
- the ring member having a plurality of first members in an alternating V-pattern forming sixteen apices at each of the ring first end and second end;
- and
- an elongate member having a first end portion and a second end portion, the second end portion being affixed to the first end of the body first portion and the elongate member first end portion extending exterior of the patient.
