Distal protection devices and methods of providing distal protection
First Claim
1. A filter for use during a procedure performed in the vasculature, comprising:
- A first spiral shaped support member;
A second spiral support member joined to the first spiral shaped support member only at a first end and a second end so as to form a moveable cross over point where the first and the second support members cross;
A first generally planar support frame and a second generally planar support frame formed by the first and second support members, the first support frame extending between the first end and the movable cross over point and the second support frame extending between the movable cross over point and the second end;
A tether on one of the first end or the second end; and
A capture structure attached to the first support frame or the second support frame, and extending in a non-planar fashion relative to the generally planar first or second support frame to which the capture structure is attached.

Abstract
A filter and methods of use to provide distal protection during a vascular procedure is provided. The filter includes a first spiral shaped support member joined to a second spiral support member to form a crossover and to form a first generally planar support frame and a second generally planar support frame. A tether is on one of the first end or the second end and a capture structure is attached to the first support frame or the second support frame. The capture structure extends in a non-planar fashion relative to the generally planar first or second support frame to which the capture structure is attached. After use to capture debris, the filter is recovered in a manner to close while maintaining captured debris within the filter.
