Patent ID: 7927350

Claim:
A method for reducing emboli formation, comprising: inserting an embolic protection device within a lumen distal to an area of treatment, the embolic protection device including a guidewire; causing the embolic protection device to expand from a collapsed configuration to an expanded configuration; passing a medical device over the guidewire and performing a medical procedure in the area of treatment within the lumen adjacent to the embolic protection device; removing the medical device from the guidewire; passing a catheter over the guidewire, the catheter including first and second expandable members associated with the catheter, expanding the first expandable member thereby causing the second expandable member to expand; unexpanding the first expandable member and moving the catheter proximally from the area of treatment causing material extending into the vessel to be scraped off or knocked free by the expanded second expandable member; and retrieving the embolic protection device from the lumen.
