Patent ID: 7014648

Claim:
A medical device comprising: a tubular member having a proximal end, a distal end, and a lumen extending therebetween; an adjustable filter comprising a frame and a mesh disposed about the frame, the frame being generally circular when deployed and having a first point on the circular frame, a first arc extending 180° from the first point to a second point on the circular frame that is opposite the first point, and a second arc extending 180° from the first point to the second point, the filter being deployed by advancing the frame distally through the tubular member with the second point leading and the first point trailing; an elongate member slideably inserted through the lumen of the tubular member, the elongate member having a distal end associated to the frame at the first point; and a cantilever beam having a proximal end, a distal end, and a cross-section, the distal end of the cantilever beam associated with the second point of the adjustable frame, wherein the proximal end of the cantilever beam is slideably associated with the distal end of the elongate member.
