The Autotome RX Cannulating Sphincterotome has a center-lumen design* that is the result of DirecTip Technology. The center lumen allows the guidewire to extend from the center of the sphincterotome to aid in positioning and facilitates wireguided cannulation. Wireguided Cannulation may help reduce the risk of post-ERCP pancreatitis compared with the standard contrast injection method.
