First Claim
Patent Images
1. A distal protection device for use with a catheter during a vascular procedure comprising:
- a tube having a proximal end and a distal end and a tube lumen extending therethrough;
an elongate wire extending through the tube lumen;
an expandable filter having proximal and distal ends, wherein at least one of the filter ends is fixedly attached to at least one of the distal end of the tube or the wire; and
an expandable occluder having a proximal end and a distal end positioned within the filter.

Abstract
An elongate distal protection device includes an intraluminal filter-occluder combination positioned at a distal end thereof. An expandable occluder is disposed within an expandable filter such that the filter and occluder are independently deployable. During use, the expanded occluder may be used first to stop embolic particles for aspiration thereof. Then, the occluder may be collapsed, leaving the filter expanded to capture any remaining embolic particles.

12. A method for treating a vessel comprising:
-
introducing a distal protection device into the vessel, the distal protection device including an expandable filter and an expandable occluder disposed within the filter, wherein both the filter and the occluder are in a collapsed configuration;
positioning the distal protection device downstream of a treatment site;
introducing a therapeutic catheter into the vessel;
positioning the therapeutic catheter at the treatment site;
expanding the filter;
expanding the occluder;
treating the vessel at the treatment site;
collapsing the occluder;
