Increased suction capability

With thinner sheath, the space between the instrument channel and FlushKnife is enlarged. It enables increased suction performance while stabilizing the sheath.
Smaller bending radius

By adopting thinner sheath and more flexible material, slim type FlushKnife is capable of bending more acutely.
Smoother scope insertion

Resistance during scope insertions is reduced by enhanced flexibility and thinner sheath. Less kinking is likely to reduce stress on physicians.
Effective water jet function

Even with thinner sheath, water jet function is same as conventional type, and the knife maintains its sharpness throughout the procedure.
