ABSTRACT:
An emboli capturing system captures emboli in blood flowing in the vasculature. The emboli capturing system includes a guidewire having a longitudinal axis and defining a lumen along at least a portion thereof. An expandable member is coupled to a distal portion of the guidewire and has an interior being in fluid communication with the lumen in the guidewire. The expandable member is configured to receive fluid through the lumen to expand radially outwardly relative to the guidewire and have fluid removed from the interior thereof to collapse radially inwardly relative to the guidewire. The expandable member, when expanded, has a spaced portion thereof spaced radially outwardly from the guidewire. An emboli capturing device is coupled to the expandable member and is configured to deploy radially outwardly relative to the guidewire upon expansion of the expandable member.
