Product Details

DirecTip™ Technology

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.1

DirecTip Technology enables the guidewire and contrast to be directed into the duct from the center of the tip, helping the physician inject contrast into the intended duct. The tapered tip enables placement into small or tight orifices.

*Does not apply to the 4.9Fr size.


Direct Wire Technology™ is designed for flexibility and responsiveness to aid in precise sphincterotomy

  • Tip orientation and cut-wire positioning capabilities developed to facilitate cannulation
  • Range of tapered tip sizes: 3.9F (1.30mm), 4.4F (1.47mm) and 4.9F (1.63mm) tip sizes to accommodate varying patient anatomy
  • 5cm – 7cm exchange length engineered for single-operator control
  • Option to transition from over-the-wire to short-wire ERCP technique without removing devices from the endoscope
