Device Features

Center Guidewire Lumen design allows the guidewire to extend from the center of the sphincterotome to aid in positioning and facilitates wire-guided cannulation.*

Wire-guided Cannulation is known to reduce the risk of post-ERCP pancreatitis compared with the standard contrast injection method.1

Center Injection Lumen design allows injection of contrast to exit from the center of the catheter enabling delivery of contrast to the intended duct.

Sphincterotome design accommodates Multiple Guidewire Diameters from 0.018 - 0.035in and allows for use of multiple guidewires during a procedure.*

Sphincterotome Multiple Tip Sizes accommodate varying patient anatomies and facilitates cannulation:

* TRUEtome 3.9F Sphincterotome accepts a maximum guidewire of 0.025in

  • 3.F=1.30mm
  • 4.4F=1.47mm
  • 4.9F = 1.63mm
  • 0.018in = 0.46mm
  • 0.025in = 0.64mm
  • 0.035in = 0.89mm

Controlled Steerability provides optimal positioning for ERCP cannulation and sphincterotomy. Steerability enables intraductal selective cannulation to aid in accessing the pancreatico-biliary tree.

Handle Brake helps maintain catheter bow for all tip sizes and added control during sphincterotomy.
