摘要：
A filtering sheath includes an elongated tubular member defined by a circumferential wall and having a distal end, a proximal end, and a lumen extending therebetween. The distal end has a plurality of slits extending through the circumferential wall, the plurality of slits defining an expandable filter region. The plurality of slits are arranged in a pattern that allows the expandable filter region to move between a first, contracted configuration, and a second, expanded configuration.
