1. A method of providing embolic protection, comprising:

  • delivering a filter carrier through a vascular system of a patient;

    delivering a filter element on the filter carrier to a location within a blood vessel that is distal to a treatment location, the filter element being delivered in a collapsed stored position for movement through the vascular system;

    expanding the filter element to an expanded position in which the filter element at least partially contacts a wall of the blood vessel such that blood passing through the blood vessel is delivered through the filter element but embolic material in the blood is retained in the filter element;

    performing an interventional procedure at the treatment location;

    advancing a retrieval catheter over the filter element;

    at least partially collapsing the filter element; and

    withdrawing the retrieval catheter and filter element from the blood vessel.
