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.

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 CO

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.
