Abstract
Devices and methods for facilitating access to the pancreaticobiliary system are disclosed. In particular, the methods include bending a device having an elongate body with a first lumen, a second lumen, and respective first and second exit openings. The methods include inserting a first guidewire through the first lumen and out of the first exit opening to cannulate a pancreatic duct, and inserting a second guidewire through the second lumen and out of the second exit opening to cannulate a biliary duct.
Claims20
A device for accessing anatomical openings in the pancreaticobiliary system of a patient, the device comprising:
- an elongate body that includes a proximal end, a tapered distal end configured to bend so as to approach the anatomical openings, a first lumen extending between the proximal end and a first exit opening at the tapered distal end, and a second lumen extending from the proximal end to a second exit opening at the tapered distal end,
- wherein the first and second exit openings are configured relative to each other so at the same time, each of the first and second exit openings faces a corresponding anatomical opening.
A method of accessing a biliary duct and a pancreatic duct of a patient, the method comprising:
- bending an elongate body having a first lumen, a second lumen, and respective first and second exit openings;
- inserting a first guidewire through the first lumen and out of the first exit opening to cannulate a pancreatic duct;
- and
- inserting a second guidewire through the second lumen and out of the second exit opening to cannulate a biliary duct.
