shield” (id. at col. 5, ll. 25-28). Figure 13 of Vallelunga is reproduced
below:
Figure 13 depicts a butterfly needle 10, a tube connector 19, and flexible
tubing 16 in a two dimensional serpentine arrangement.
As discussed above, the term “coil” can be interpreted more broadly
than a three-dimensional spiral, and can be interpreted to include the two-
dimensional structure depicted in Figure 13. However, claim 1 requires a
coiled structure made from a “plurality of helical turns.” We agree with
Appellant that Vallelunga does not describe a coil established by a plurality
of helical turns, that is, a three-dimensional spiral. In addition, although the
Vallelunga device may well be capable of effecting a coiled configuration in
the shape of a helix, we do not agree that this is sufficient to anticipate
claim 1, which requires a “flexible tube including a plurality of helical turns
