Abstract
A filter device is adapted to function as a guidewire, an exchange guidewire, and provide embolic protection during a procedure. The filter device includes a filter assembly that is either integral with or coupled to a guide member. The filter assembly includes a plurality of struts that expand outwardly to deploy a filter that collects or captures material flowing along the blood vessel within which the filter device is deployed. The plurality of struts are constrained by a restraining member or mechanism that prevents the plurality of struts from expanding or extending outwardly to deploy the filter. Cooperating with the restraining member or mechanism is an actuating assembly that is adapted to release the restraining member or mechanism and enable the filter to be deployed from the guide member. A capture catheter that cooperates with the filter device and substantially surrounds the filter during removal of the filter device.
