Abstract
A distal protection device for use in a body lumen. The device includes a functional element which may be a filler or an occlusive element. The device includes means for controlling the movement and placement of the functional clement along a guidewire. Motion of the guidewire can be independent of the motion of the functional element.

1-33. (canceled)
A distal protection device for use in a body lumen, the distal protection device comprising:
- a first elongate member having distal and proximal ends;
- a second elongate member having distal and proximal ends, the second elongate member being carried by and connected to the first elongate member;
- a functional element carried by the second elongate member, the functional element being expandable from a delivery configuration to an expanded deployed configuration;
- and
- a shock absorber connected to the first elongate member and one or both of the second elongate member and the functional element, wherein the shock absorber is configured to change an axial distance from a proximal end to a distal end of the shock absorber in response to relative movement between the first and second elongate members such that the first elongate member may be moved relative to the second elongate member without resulting in corresponding movement of the functional element.

A method comprising:
- introducing a distal protection device into a lumen of a vessel of a patient with a functional element of the distal protection device in a delivery configuration, the distal protection device comprising:
- a first elongate member having distal and proximal ends;
- a second elongate member having distal and proximal ends, the second elongate member being carried by and connected to the first elongate member;
- the functional element carried by the second elongate member, the functional element being expandable from a delivery configuration to an expanded deployed configuration;
- and
- a shock absorber connected to the first elongate member and one or both of the second elongate member and the functional element, wherein the shock absorber is configured to change an axial distance from a proximal end to a distal end of the shock absorber in response to relative movement between the first and second elongate members such that the first elongate member may be moved relative to the second elongate member without resulting in corresponding movement of the functional element;
- and
- expanding the functional element within the lumen to a deployed configuration.
