Abstract
The present invention is a collapsible blood filter for use during a vascular procedure, such as angioplasty or stent deployment. A filter made of braided filaments is located on the distal end of a delivery member, and the filter is deployed downstream of the vascular treatment site to capture emboli released during and immediately after the procedure. Optimal braid geometry of the filter ensures that captured emboli will be retained during collapse and removal of the filter following the procedure.
