ABSTRACT:
An intravascular filter having a filament which expands a filter element. The filament is a coil which is stretched to reduce the diameter of the coil for introduction. The filter element is preferably biased toward the closed position and is opened by the coil when tension is released on the coil. The filament slides along the internal surface of the filter element so that the filter element may assume intermediate positions.
