ENDOSCOPIC VESSEL HARVESTING
SAPHENOUS VEIN PROCEDURE-AT-A-GLANCE
Incision
Create an incision in the area near the knee, over the greater
saphenous vein. Attach the Dissection Tip to the end of the
7 mm endoscope. Insert the 7 mm endoscope into the
incision and visualize on the video monitor.
Initiating CO2Insufflation
Advance the Short Port Blunt Tip Trocar (BTT) into position,
and insufflate CO2gas to create a tunnel. Perform anterior,
posterior and branch dissection with the Dissection Tip.
Cauterizing and Transecting Branches
Insert the VASOVIEW 7 Harvesting Cannula to cauterize and
transect branches, using the BiSECTOR™ Bipolar Ligating
Forceps.
Enhanced Visualization
For enhanced visualization during vessel branch cauteriza-
tion and transection, transfer the CO2source from the BTT
CO2 Insufflation Port to the Distal Insufflation CO2Port on the
VASOVIEW Harvesting Cannula.
Running the Vessel
Deploy the C-Ring from the VASOVIEW Harvesting Cannula,
engage the vein with the C-Ring and run the length of the vein
to ensure that it is completely free and no branches remain.
Transection and Retrieval
Make a stab wound over the distal end of the tunnel, clamp
the saphenous vein, externalize it through the stab wound.
Transect the vein. Ligate the terminal end of the vein. Retrieve
the harvested vein from the original incision at the knee.

RADIAL ARTERY PROCEDURE-AT-A-GLANCE
Initiating CO2Insufflation
Insert the Short Port Blunt Tip Trocar (BTT) into position and
begin CO2 insufflation. Perform anterior, posterior, and lateral
dissection of the radial artery pedicle with the Dissection Tip
on the 7 mm endoscope.
Fasciotomy
Insert the VASOVIEW 7 Harvesting Cannula. Using the
BiSECTOR™ Bipolar Ligating Forceps, release the fascia,
cutting it from the distal to the proximal forearm.
Cauterizing and Transecting Branches
Use the C-Ring to protect the radial artery pedicle and expose
the branches. Using the BiSECTOR tool, cauterize and
transect branches.
Running the Vessel
Deploy the C-Ring from the VASOVIEW 7 Harvesting Cannula,
engage the radial artery with the C-Ring and run the length of
the artery to ensure that it is completely free and that no bran-
ches remain.
Transection and Retrieval
Make a stab incision near the elbow, clamp the radial artery
pedicle and externalize it through the stab incision. Transect
the radial artery. Ligate the proximal radial artery, and then in
retrograde fashion, retrieve the radial artery pedicle from the
original incision at the wrist.
Incision
Beginning just proximal to the wrist crease, create a
longitudinal incision. Attach the Dissection Tip to the end of
the 7 mm endoscope. Insert the 7 mm endoscope into the
incision and visualize on the video monitor.
