Rotatable sphincterotome is used for cannulation of the ductal system and for sphincterotomy, if preloaded, also aids ERCP operation in the stenosis of bile duct difficult stricture.
Features of Rotatable Sphincterotome
Tapered tip enables easy cannulation.
Insulating coating minimizes the risk of tissue damage as well as endoscopic contact.
Pre-curved tip assists cannulation efficiency and reduce operation time.
Colored markers for precise positioning under endoscopic view.
Double-lumen and triple lumen sphincterotome are both available.
Preloaded with 0.035" LeadCross.
360° 1:1 rotation facilitates cannulation.

Comparison Between a Rotatable Sphincterotome and a Conventional Sphincterotome
The conventional sphincterotome consists of a metal wire with insulating coating, with the distal 20–30 mm of wire exposed, and a short radio-opaque, tapered tip. Cannulation is usually attempted
with a sphincterotome at present time. The conventional sphincterotome is designed to perform sphincterotomy at the 12 o'clock orientation, while a rotatable sphincterotome for ERCP in B-II
patients or when cannulation/therapeutic interventions entails orientation other than the standard 11–1 o'clock position.
