with Confidence and Efficiency

The V-System is a complete system that integrates Olympus endoscopes and EndoTherapy devices. The revolutionary

V-System design offers the option of guidewire manipulation by the physician or the assistant, allows easier exchange

The balloon can be inflated to

one of three diameters— 8.5mm,

11.5mm, and 15mm. The balloon size can

be easily adjusted to suit the requirements

and conditions of each case so there is

no need to change catheters during

the procedure.

Now endoscopists have the option to

manipulate guidewires and devices.

The convenient C-Hook allows the device handle to be attached to the

endoscope's control section, putting it within easy reach of the endoscopist.

With the device handle right at hand, the endoscopist can maneuver the

guidewire, inject contrast media, and manipulate the handle — all while keeping

a grip on the scope control section.

V-Marking

Indicates when to raise and lower

the V-Groove forceps elevator.

The exclusive V-Marking 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 tip has reached the distal end of the scope and the V-Groove

forceps elevator may be lowered. When withdrawing the device from the scope,

the same marking indicates when to raise the elevator to lock the guidewire.

V-Sheath

Device control by the endoscopist

or the assistant.

The V-Sheath allows the endoscopist complete device control or, if preferred,

device control may be given to the assistant. The unique device design allows

The guidewire and injection lumens are separated to

The balloon catheter sheath is manufactured from a

special material that allows it for improved insertion

into the papilla, ensuring smoother guidewire passage,

and facilitating contrast injection. The tapered design

— 7 Fr. catheter at the proximal end tapers to 5 Fr. at

the distal end — enables an easy approach to the bile

duct and accommodates a 0.035" guidewire.
