Abstract:
A sphincterotome includes a plurality of tines that are longitudinally disposed at a distal end of the sphincterotome. One of the tines is configured as a cutting wire of the sphincterotome and is electrically coupled to an electrical source. The other tines are configured as stabilizing wires to stabilize the cutting wire in a cutting position. In addition, the other tines are electrically insulated from the cutting wire and the electrical source. The plurality of tines are movable between an expanded and a non-expanded configuration. Electrocautery is performed when the tines are in the expanded configuration.
