Abstract

SE DESCRIBE UN ESFIRTEROTOMA (21) TAL COMO UN PAPILOTOMA, PARA CISION O INCISION QUIRURGICA, UTILIZANDO UN ALAMBRE CORTADOR (33) CONDUCTIVO ELECTRICAMENTE. EL ESFINTEROTOMA (21) INCLUYE UN ELEMENTO (27) TUBULAR MULTILUMEN, CON UN LUMEN (55) QUE TIENE UN CONDUCTOR (43) ELECTRICO EN SU INTERIOR, Y EL OTRO LUMEN (57) TIENE UN ALAMBRE DE REFUERZO EN SU INTERIOR. EL ALAMBRE (45) DE REFUERZO ES PREFERENTEMEMTE RECATANGULAR, EN SECCION TRANSVERSAL, PROPORCIONANDO UN MOMENTO DE INERCIA MAYOR EN UN EJE R RESISTENTE QUE EN UN EJE B DE PLEGADO. DE COMNFORMIDAD CON ESTO, EL BORDE (53) DE CORTE DEL ALAMBRE (33) DE CORTE PUEDE ORIENTARSE A LA POSICION DE LAS 12 DEL RELOJ, DEL ORIFICIO PAPILAR, PARA EVITAR DAÑO A LA PARED DUODENAL DEL CONDUCTO (69) PANCREATICO EN EL PACIENTE, Y MANTENER EL BORDE DE CORTE (53) EN UN PLANO P PREDETERMINADO DE CORTE. LISTAS O RAYAS (39, 41) DE INDICACION FLUROSCOPICA PUEDEN ESTAR PROVISTAS EN EL EXTREMO DISTANTE (23) DEL ESFIRTEROTOMA (21). TAMBIEN SE DESCRIBEN UN METODO Y UN USO DEL METODO DE FABRICACION DE LA PRESENTE INVENCION.
