摘要：
There are disclosed embodiments of a system for retrieving a filter device from within a patient. A tube or sheath and one or more cables or other elongated members, which include a protrusion such as a bead at or adjacent a distal end, are movable with respect to each other. When the tube or sheath is adjacent a filter device, the cable or elongated member is extended so that the protrusion is between or through wires of the filter, and the protrusion is engaged to or between two or more of the wires. The filter is placed within the tube or sheath, as by retracting the cable or elongated member to pull the filter, by moving the tube or sheath over the cable or elongated member while it engages the filter under tension, or both.
