In Figure 6, the tubular member has tassels 148 which extend
past the end of the coil. Phelps states that this feature
provides additional occlusion area and adds very little to the
volume of the device as it passes through the catheter lumen.
In Figure 11, the fibrous braided portion 166 is constructed
to have exposed fiber elements 168 sticking out from the fiber
braided portion 166 to enhance the ability of the device to
effectively fill the space at the target within the patient's
vasculature.
Dormandy discloses an embolization device comprising an
elongate coil having a plurality of turns and a group of
fibers. The group of fibers has an intermediate portion and
first and second end portions. The intermediate portion is
looped about one of the turns of the coil to form a loop on
one of said turns. The end portions extend interiorly of the
coil and outwardly of the coil through two adjacent turns
adjacent the turn about
which the loop is formed. The ends of the fibers of the end
portions of each group are free to move. The group of fibers
