Abstract:
A method for the capture and removal of embolic material from a blood vessel during an interventional procedure comprising:advancing a guidewire through a vasculature; crossing a desired treatment location with the guidewire; advancing over the guidewire a collapsible embolic protection filter having a collapsed configuration, the collapsed configuration permitting delivery and withdrawal of the filter; deploying the filter distal to the treatment location; introducing separate from the embolic protection filter an interventional device over the guidewire to the treatment location for carrying out the interventional procedure, embolic material generated during the treatment procedure being captured by the deployed filter; advancing a retrieval catheter over the guidewire; collapsing the filter into the retrieval catheter with the captured embolic material; and withdrawing the retrieval catheter and the collapsed filter from the vasculature.
