In focus groups with surgical clinicians, Terumo Cardiovascular Systems identified a need for a simple and intuitive device and a comprehensive and advanced training programme in order for clinicians to successfully learn and perform endoscopic vein harvesting.
The VirtuoSaph EVH System features innovative disposable endoscopic tools that are inserted through a small leg incision to dissect and harvest the saphenous vein. An Olympus brand endoscope, designed exclusively for the system by Olympus, allows the clinician to view the endoscopic procedure in real time on a monitor. The easy-to-use disposable tools include a trocar, a dissector rod, and a harvester rod that enable one-handed manipulation and easy conversion between tools during the procedure. In the United States, Terumo Cardiovascular Systems provides all the hardware components necessary to perform endoscopic vein harvesting, including the Olympus UES-40 generator, VISERA camera processor unit, and light source.
Studies show that surgical residents trained on simulators made fewer errors and operated more quickly than those who received the traditional "see one, do one, teach one" training, in which residents observe experienced doctors, do procedures under supervision and then independently, and later train others.
Terumo Cardiovascular Systems has combined the VirtuoSaph EVH System with the Terumo Endoscopic Simulator. Masao Hitotsuyanagi, Director, and General Manager, Advanced Surgical Technologies Business Unit, Terumo Cardiovascular Systems, stated: "When a world-class medical device is combined with world-class training the result is better patient outcomes." The simulator was developed in an intensive collaborative effort with Immersion Medical, an expert in virtual reality medical simulators.
This real-time, virtual reality training programme provides haptic or touch feedback using Immersion Medical's Accutouch technology. Designed for participants to gain dexterity and confidence with both the product and the procedure, the unique two-day training programme enables clinicians to practise all areas of the EVH procedure repeatedly in virtual reality to reach proficiency more quickly.
The VirtuoSaph Endoscopic Vein Harvesting System will be marketed by Terumo Cardiovascular Systems in the United States and by Terumo companies around the world.
