1. An embolic protection filter, comprising:
- an elongate filter wire;
a proximal stop coupled to the filter wire;
a distal stop coupled to the filter wire and disposed distally of the proximal stop a first distance;
a filter coupled to the filter wire, the filter comprising;
a filter loop, a proximal tubular member, a strut extending between the filter loop and the proximal tubular member, a filter membrane coupled to the filter loop and extending distally therefrom, a distal tubular member coupled to the filter, and a connecting tube disposed over the filter wire and connected to both the distal tubular member and the proximal tubular member; and
wherein the proximal tubular member has a length and wherein the length of the proximal tubular member is shorter than the first distance between the proximal stop and the distal stop so that when the proximal tubular member is disposed between the proximal tubular member and the distal tubular member the filter wire can be moved independently of the filter.

Abstract
Embolic protection filtering devices and methods for making and using the same. An example filtering device includes a filter wire, a filter slidable over the filter wire, and a filter membrane coupled to the filter frame. The filter wire includes a plurality of stops. The filter includes a proximal tubular member, a distal tubular member, and a connecting tubular member extending between the proximal tubular member and the distal tubular member.

8. An embolic protection filtering device, comprising:
-
a first tubular member having a first length;
a second tubular member having a second length;
a connecting tubular member, the connecting tubular member having a first end coupled to the first tubular member, and a second end coupled to the second tubular member;

15. A method for filtering embolic debris in a body lumen, comprising the steps of:
-
providing an embolic protection filtering device, the device comprising;
a first tubular member having a first length, a second tubular member having a second length, a connecting tubular member, the connecting tubular member having a first end coupled to the first tubular member, and a second end coupled to the second tubular member, a filter disposed adjacent the connecting tubular member, the filter having a strut region coupled to the first tubular member and a filter region coupled to the second tubular member, a filter wire slidably extending through both the first tubular member and the second tubular member, a first stop coupled to the filter wire, and a second stop coupled to the filter wire and disposed distally a first distance from the first stop, wherein the first length is shorter than the first distance;
advancing the filter wire through a body lumen to a position adjacent an area of interest;
advancing the filter over the filter wire to a first position where the second tubular member is disposed between the first stop and the second stop;
further advancing the filter over the filter wire to a second position where the first tubular member is disposed between the first stop and the second stop; and
deploying the filter. - View Dependent Claims (16, 17, 18, 19, 20)
