The distal end of this product is pre-curved. The construction of distal end and pre-curved shape facilitates easy position and insertion into the papilla.
It will be used as a guide wire, cutting wire and injection of contrast media and the excellent configuration of 3 lumens facilitates efficient orientation of cutting wire for easy sphincterotomy.

The distal end of sheath is tapered for easy cannulation into the papilla. It is also used for stricture and minor papilla.
Using coating on the proximal end of the cutting wire minimizes the damage to the surrounding tissue of targeted lesion and reduces the possibility of contact between conductive cutting wire and endoscope.
