said catheter body having a proximal end and a distal tip
and at least three independent lumens extending lengthwise
thereof, each said lumen having an entry port at the proximal end
thereof and at least a first lumen and a second lumen of said at
least three independent lumens having axially facing exit ports
disposed in said distal tip, the first lumen being configured for
receiving a wire guide and the second lumen being configured for
injection of contrast fluid, and
wherein a third lumen of the at least three lumens has an
electrosurgical instrument configured to form a
sphincterotome/papillotome disposed therein.
92. A catheter assembly for advancement and manipulation
through the accessory channel of an endoscope into a body passage
within the gastrointestinal system, the catheter assembly
comprising:
an elongate catheter body having a proximal end and a distal
end;
a first elongate lumen extending from the proximal end to
the distal end of the catheter body, the first elongate lumen
configured for receiving a guide wire and having an entry port at
the proximal end of the catheter body and an exit port the distal
end of the catheter body;
a second elongate lumen extending from the proximal end to
the distal end of the catheter body, the second elongate lumen
being configured forinjection of tracer dye out the distal end
of the elongate catheter body, such that tracer dye may be
released from the distal end of the elongate catheter body while
a guide wire is disposed in the first lumen; and
a third elongate lumen extending from the proximal end of
the catheter body toward the distal end of the catheter body, the
third lumen having an electrosurgical tissue cutting instrument
disposed therein.
97. A catheter assembly for advancement and manipulation
through the accessory channel of an endoscope into a body
passage, the catheter assembly comprising:
an elongate catheter body having a proximal end and a distal
end having a distal tip;
