first corporeal lumen, wherein the second corporeal lumen
branches from the first corporeal lumen; and using a catheter
(34) having a mechanical expanding means thereon to advance the
repair device (22) from the entry point in the second corporeal
lumen to the first corporeal lumen, the repair device being
carried in a collapsed form on the exterior of the catheter and
in association with the mechanical expanding means. Once the
repair device is properly positioned in the first corporeal lumen
at the site needing repair (Fig. 1), the mechanical expanding
means is operated to cause expansion of the collapsed repair
device and to cause the anchoring pins (28) at each end of the
repair device to pierce the healthy artery wall (18) on opposite
ends of the aneurysm, thus anchoring the repair device in place
(Figs. 2 and 4). Choudhury notes that his invention is intended
to provide a more favorable mortality rate as a result of the
less severe surgical technique involved therein.
In contrast to Choudhury, Kononov discloses a highly
invasive, major form of surgery and an aneurysm repair device for
use therein. As noted on page 2 of the translation, the surgery
begins by uncovering the bifurcation of the aorta on the left,
starting from a retroperitoneal entrance at the patient's back,
