  • Streamlined Dissection Tip - Designed for ease of dissection, improved tunnel creation, and optimal clarity.
  • Closed-System Insufflation - A closed system, with CO2 insufflation, designed to create clear long tunnel views, using innovative focal distal insufflation for further reaching visualization.
  • BiSECTORTM or Scissors - Proven flexible format lets you choose tip options with a bisector or scissors. Maximized tool extension and rotation mean optimal maneuverability for harvest of the saphenous vein or radial artery.
  • Robust 7 mm Endoscope - An improved, more robust 7mm scope delivers extended reach, letting you get the most from each harvest.
  • Familiar Platform - Familiar platform with responsive controls enables you to work confidently and enjoy immediate productivity.

Endoscopic Vessel Harvesting with VASOVIEW can improve patient outcomes with:

  • A less-invasive 2 cm (1 inch) incision
  • Significantly less risk of infection and wound complications1
  • More rapid recovery and far less postoperative pain1
  • Efficient harvest of either sapheonous vein or radial artery1

EVH Procedure

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 use as “new” vessels for bypass grafts.

There are three techniques for harvesting a vessel for a CABG procedure:  open, bridging and EVH. EVH uses special instruments to view and remove a blood vessel with much less trauma to the vessel itself 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.

EVH is minimally invasive and uses special instruments to view and remove the blood vessel. EVH usually only requires one small incision about one inch long. The EVH procedure is performed immediately before 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

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:

  • Significantly less risk of infection and wound complications
  • Less postoperative pain and swelling
  • Faster recovery with minimal scarring
  • Greater patient satisfaction
