Abstract: A medical device for resecting a tissue. The medical device includes an elongate shaft having a distal end, a proximal end, and a plurality of channels extending therebetween. The medical device also includes a cap assembly disposed at the distal end of the elongate shaft. The cap assembly includes a housing having a proximal portion, a distal portion, and a cavity extending therebetween. The housing is configured to be transparent and includes a friction surface pattern disposed over a portion of an outer surface of the housing. The cap assembly further includes one or more ligation bands disposed on the proximal portion of the housing. The cap assembly also includes a wire interwoven between the ligation bands. The wire is further configured to roll at least one ligation band at a time towards the distal end of the distal portion.

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.
