FILTERING DEVICE FOR USE WITHIN A BODY LUMEN
First Claim
1. A filtering apparatus for collecting embolic debris in a body lumen, comprising:
- a core wire extending from a proximal end to a distal end of the distal protection device; and
a filtering device positioned proximate the distal end of the distal protection device with the core wire extending there through, the filtering device includinga tubular member having an outer surface for apposition with a vessel wall defining the body lumen and an inner surface defining an interior of the tubular member, anda filter member positioned within the interior of the tubular member, the filter member having a proximal end coupled to the core wire, a distal end attached to the tubular member, and an outer surface facing the inner surface of the tubular member, wherein a collection chamber is defined within the tubular member and outside the filter member.

Abstract
A filtering apparatus for collecting emboli or thromboli in a body lumen. The apparatus may be a temporary filtering device mounted on a core wire for use during interventional procedures or a semi-permanent filtering device that is left within a body lumen for a therapeutically appropriate length of time. The filtering device includes a tubular member having an outer surface for apposition with the body lumen and a filter member positioned within an interior of the tubular member. The fitter member includes an apex at a proximal end that is positioned along a longitudinal axis of the filtering device, a distal end attached to the tubular member, and an outer surface facing an inner surface of the tubular member.
