is movable with the structure during expansion thereof and is
capable of substantial sealing engagement with a wall of a
blood vessel to interrupt blood flow therethrough and is non-

Chu discloses catheters for draining that are to be placed
in a body organ or vessel for a prolonged period of time
(col. 1, lines 5-8). To prevent retrograde movement out of the
organ or vessel, the catheter includes a multi-shapeable,
flexible woven mesh tube disposed between the proximal and
distal ends of the catheter (col. 1, lines 24-29). The woven
tube is foraminous and axially and radially elastically
extensible, and allows free and unobstructed flow of fluids
therethrough (col. 2, lines 52-56; col. 4, lines 1-3).
Guenther discloses a triple catheter comprising outer,
intermediate and inner catheters for removing blood clots from
arteries and veins (abstract; col. 1, lines 6-13). The
intermediate catheter has a mesh or weave of spring wires or
elastic plastic monofilaments that is covered by or embedded in
an elastic plastic material (col. 2, lines 29-33). The coating
or embedding matrix material “prevents damage to the inner walls
of the blood vessel and also prevents the radial leaking of
