Abstract: Constructive disposal placed in artifon catheter applied in perforations above the papillae in fistula-papillotomy, where the procedure known as Endoscopic Retrograde Cholangiopancreatography (ERPC) is characterized by the combination of instrumental transpapillary access and the obtaining of contrasting images through pancreatic bile, a result obtained through the use of the artifon catheter device (A) claimed herein, which regards a perforation catheter above the papilla in fistula-papillotomy, to obtain access to biliary passages, making way for an alternative to known surgical techniques, this artifon catheter device (A) presenting a constructive concept composed of a Y connector component (1); a manipulating component of the concentric perforating tube (2); an external concentric tube component (3), within which a concentric perforation tube component (4) is located of which the far end is connected to a needle component (5); radiopaque marks components (6); a manipulating component of the external conce
