(column 3, lines 67 and 68), the latter being “reabsorbed by
the organism after a certain time after their implantation”
(column 6, lines 5 and 6). Of particular interest is Duran’s
teaching that
[f]or implantation the stent [or ring] 1 is
covered with biocompatible cloth. In this regard
biocompatible cloth comprises a fabric mesh of
biocompatible material, preferably polyester
(polyacetate) fabric. The use of such biocompatible
fabric mesh to enclose various plastic or metal
members which are subsequently surgically implanted
in the human body is well known in the art. As is
further known, after implantation into the human
body, an ingrowth of fibrous tissue usually forms in
the interstitial spaces of the fabric, and
endothelial cells cover the fabric to provide a
nonthrombogenic autologous surface [column 6, line
60, through column 7, line 3].
Anticipation is established only when a single prior art
reference discloses, expressly or under principles of
inherency, each and every element of a claimed invention. RCA
Corp. v. Applied Digital Data Sys., Inc., 730 F.2d 1440, 1444,
221 USPQ 385, 388 (Fed. Cir. 1984). It is not necessary that
the reference teach what the subject application teaches, but
only that the claim read on something disclosed in the
reference, i.e., that all of the limitations in the claim be
found in or fully met by the reference. Kalman v. Kimberly
