Advanced Technology in a Familiar Format
The Vasoview 7xB Endoscopic Vessel Harvesting System was designed with early generation EVH users in mind. If you are most comfortable with a two-handed format, the 7xB platform with its advanced, responsive controls enables you to work confidently and enjoy immediate productivity.
The harvesting system's robust 7mm scope delivers extended reach, letting you get the most from each harvest.
Endoscopic Vessel Harvesting with a Vasoview System provides the following benefits versus open EVH:
Streamlined Dissection Tip
Designed for ease of dissection, improved tunnel creation, and optimal clarity.
A closed system, with CO2 insufflation, designed to create clear long tunnel views, using innovative focal distal insufflation for further reaching visualization.
Maximized tool extension and rotation results in optimal maneuverability for harvest of the saphenous vein or radial artery.
7 mm Extended Length Endoscope
The 7 mm Extended Length Endoscope with Dissection Tip is indicated for visualization of a surgical cavity and dissection in endoscopic procedures and other minimally invasive surgical procedures allowing access for vessel harvesting, and is primarily indicated for patients undergoing endoscopic vessel harvesting for arterial bypass.
Extremity procedures include tissue dissection/vessel harvesting along the saphenous vein for use in coronary artery bypass grafting and peripheral artery bypass or radial artery for use in CABG.
EVH stands for Endoscopic Vessel Harvesting. During a Coronary Bypass procedure, one or more healthy blood vessels will be taken (or “harvested”) from the patient’s leg, arm or chest to be used as “new” vessels for bypass grafts. There are three techniques for harvesting a vessel from the arm or leg for a CABG procedure: open, bridging and EVH. EVH uses special instruments to view and remove a blood vessel with less trauma to the vessel or to surrounding tissues than bridging or an “open” procedure.
In the past, one long incision was made from the ankle to the groin; this procedure is called an open procedure. It is highly invasive, often caused patients more pain than their chest incision, and resulted in a long scar.
An alternative, less invasive technique to the open procedure is called “bridging”. Bridging enables harvesters to gain access to the saphenous vein through three or four smaller incisions of about three inches each.
EVH is minimally invasive and uses special instruments to view and remove the blood vessel. EVH usually requires one small incision about 2 cm long. The EVH procedure is performed at the beginning of heart surgery and can be used for the following vessels:
- The greater saphenous vein, which runs the length of the leg
- The radial artery, which runs from the wrist to the elbow in the arm
Benefits of EVH
There is generally little patient discomfort from endoscopic vessel harvesting, especially when compared to open or bridging procedures. In clinical studies, some important benefits have been shown in EVH including:
