Endoscopic products allow clinicians to perform minimally invasive procedures through very small incisions by using an endoscope to see inside the patient's body. Terumo manufactures the VirtuoSaph™ Plus Endoscopic Vessel Harvesting System, used to remove the saphenous vein or radial artery from the patient for use as a bypass graft during coronary surgery.
The VirtuoSaph™ Plus System is designed to evaluate standards for patient safety, conduit quality and ergonimics.2 The device uses an endoscopic approach to vessel harvesting with one small incision in either the leg or arm which minimizes scarring, morbidity and infection associated with traditional longitudinal incisions.
"Open" system distal insufflation with no-occlusive trocar
- May lower the risk of CO2 embolism3
- May lower risk of intraluminal clot4
A dissector rod with an atraumatic conical tip, centering rings, and CO2 delivered at the tip
- Centering rings allow the clinician to monitor the location of the dissection cone tip relative to the vessel during dissection
Unique wiper to clean the endoscope lens
- One wiper activation immediately improves visibility
- Allows cleaning in the tunnel without the need for additional fluid

The Dissector
The dissector rod has a conical tip that delivers CO2 inside the tunnel walls for increased visibility. CO2 delivered at the tip, consistently provides space in the tunnel for increased visibility.
The Harvester
The harvester has multiple features to simultaneously coagulate and cut the branches of the saphenous vein or radial artery.
The Wiper
VirtuoSaph Plus’ unique wiper mechanism quickly cleans and clears the endoscope lens to improve visibility.
The Centering ring
Centering rings in the dissector cone tip aid in visualization.
