Olympus V-System™ Fact Sheet: May 2005The revolutionary Olympus V-System, which incorporates an Olympus duodenoscope and Olympus EndoTherapy devices was first introduced in October 2004 at the American College of Gastroenterology(ACG) in New Orleans, LA. It was developed to help simplify and streamline a therapeutic procedure known as Endoscopic Retrograde Cholangio-Pancreatography (ERCP). Previously only diagnostic in nature, ERCP has evolved over the past 20 years into a primarily therapeutic procedure utilizing both endoscopic and fluoroscopic imaging to correct a problem that has been identified in the biliary and/or pancreatic ducts. ERCP has traditionally been a time consuming, complicated procedure, where cooperation and coordination between the nurse and physician is critical. The new combination is called the “V-System” because of an exclusive V-shaped groove(V-Groove) on the duodenoscope’s elevator (V-Scope) that locks the LinearGuide-V™ guidewire, allowing for easier device exchange.
The C-Hook: Facilitates greater device control
The proprietary V-System is designed for simplicity and choice while maintaining the clinical results expected from Olympus. Each accessory has a C-Hook that allows it to be attached to the V-Scope just below the instrument channel port. This allows the endoscopist greater device control and the ability to maneuver the guidewire, inject contrast media, and manipulate the device -- all while keeping a grip on the scope control section. The unique device design of the V-System also allows the handle to be separated, so if the physician chooses, control of specific devices can also be given to the assistant.
The V-Marking & V-Groove: For easier device exchange
The exclusive V-Marking on each V-System device is located on the proximal side of the sheath. When this marking reaches the channel port on the scope’s control section, it indicates that the device’s tip has reached the distal end of the scope and the V-Groove elevator may be lowered. When withdrawing the device from the scope, the same marking indicates when to raise the elevator to lock the guidewire, allowing for easier device exchange.
The V-Holder: For unprecedented efficiency and reliability during device replacement
The newest component of the V-System, the V-Holder, was introduced in May 2005 at Digestive Disease Week (DDW) in Chicago, IL. The V-Holder assists in V-System exchanges and helps ensure that the guidewire will stay in place during catheter exchange and duct sweeping. In the conventional device replacement procedure, the physician withdraws the catheter while the assistant pushes the guidewire into the catheter to prevent it from losing its position in the biliary duct. With the V-Holder, it is now possible for the physician to withdraw the device more quickly and more easily with one motion, while the guidewire stays in place.
Eric Halvorson, vice president and general manager for Olympus EndoTherapy, stated, “The development of the V-System reflects Olympus’ unique ability to meet our customers’ needs by developing a single system that combines state-of-the-art endoscopes with high-performance EndoTherapy devices.”
Gregory G. Ginsberg, M.D., associate professor of medicine and director of endoscopic services at the Hospital of the University of Pennsylvania stated, “The V-System takes something that is nerve-wracking to begin with – ERCP – and makes it simpler, easier and more precise. Being able to manipulate and maintain control of the guidewire yourself is a great advantage.”
The new V-System joins an already wide array of high performance Olympus EndoTherapy devices (over 600 in all) that integrate with Olympus endoscopic systems to help endoscopists optimize clinical outcomes and improve cost-efficiencies.
