Ensure generator wattage is set according to
recommendations in the VASOVIEW 7 xB Endoscopic
Vessel Harvesting System Instructions For Use (settings
differ by type of generator).
Always keep the BiSECTOR tool in view during coagulation.
Utilize the C-Ring to provide adequate distance between the
saphenous vein and the vessel branches to facilitate branch
cauterization and transection.
Coagulate for 1 – 2 second increments only. Monitor tissue
dehydration and blanching. Further coagulation may be
required for large vessel branches.
Keep the BiSECTOR tool and C-Ring retracted during
cannula insertion, advancement, and removal.
Remove any fat or coagulum from the BiSECTOR tool to
insure proper coagulation.
Technique Tips
Use the internal diameter of the C-Ring (5 mm) as a guide
for measuring distance. Advance the Harvesting Cannula to
the distal end of the tunnel to begin vessel branch cauteri-
zation and transection, working back towards the incision. If
branches prohibit advancement of the Harvesting Cannula,
it may be less traumatic to the vein to perform vessel
branch harvesting starting at the proximal end of the tunnel.
Always ensure the C-Ring is behind the vessel branch that
is being cauterized and transected. (Figure 26a)
After cauterizing and transecting a branch, observe for
bleeding. If bleeding is noted, spot cauterization can be
performed by advancing the BiSECTOR tool to the bleeding
point and cauterizing the bleeding area. (Figure 26b)
When cauterizing and transecting branches, be sure to have
the C-Ring as close to the branch as possible before rota-
ting. This will allow the ability to cauterize and cut the
branch further away from the vein.
When retracting the instrument with the vein in the C-Ring,
if the vein appears to be turning (or snaking) around the
instrument, rotate the Harvesting Cannula in the direction of
the turning (or snaking). Often this represents that a branch
is going to be encountered.
Always retract the BiSECTOR tool into the Harvesting
Cannula when not in use. (Figure 27)
Try to keep the C-Ring with the vein in place in the center of
the tunnel at all times. (Figure 27)
