Abstract:
1. A distal protection device for use in a body lumen comprising: a first elongate member having distal and proximal ends; a second elongate member having distal and proximal ends; and a functional element carried by the second elongate member, the functional element being expandable from a delivery configuration to an expanded deployed configuration when the functional element is deployed in the body lumen, the first elongate member having a tubular body having a lumen with an interior diameter and the second elongate member having a first region with an exterior diameter less than the interior diameter of the lumen of the tubular body, the first region being slideably received in the lumen of the tubular body, the first and second elongate members being moveable over a range of motion from a first relative position to a second relative position such that when the functional element is deployed in the body lumen the first elongate member may be moved without resulting in corresponding movement of the functional element, the distal end of the second elongate member being distal to the distal end of the first elongate member over the entire range of motion, the second elongate member having enlarged portions adjacent proximal and distal ends of the first region, the enlarged portions having exterior diameters larger than the interior diameter of the lumen of the tubular body, wherein the first elongate member has an exterior diameter, and the exterior diameter of the first elongate member and the exterior diameters of the enlarged portions of the second elongate member are approximately equal.
