Particle-removing medical device and method

摘要

A particle-removing medical device includes an outer, hollow tube having a tube distal end and a porous braided structure having a distal part and a proximal part. Structure, housed within the tube and having a distal end positioned distally of the tube distal end, is used to move the braided structure from a contracted condition to an expanded condition by moving the distal ends of the tube and the structure towards one another. The braided structure is constructed to inhibit particles from moving completely through the braided structure when in the expanded condition.
