A method for removing one or more biliary stones from a bile duct, the method comprising:

• making an incision in a subject adjacent to the bile duct;
• delivering a tube and an expandable device, via the incision, to the bile duct to a position proximal to the one or more biliary stones, wherein the expandable device is positioned with a lumen of the tube, and wherein the expandable device includes a lumen extending from a distal portion to a proximal portion;
• delivering a scope through the lumen of the tube and through the lumen of the expandable device, wherein distally advancing the expandable device includes (1) abutting a distal end of the scope with one or more radially inward extensions on an inner surface of the expandable device, and (2) distally advancing the scope to distally advance the expandable device;
• proximally retracting the tube such that the expandable device remains in the position proximal to the one or more biliary stones;
• distally advancing the expandable device such that the distal portion of the expandable device at least partially surrounds the one or more biliary stones;
• at least partially closing a distal end of the expandable device;
• and
• moving the expandable device proximally to remove the expandable device and the one or more biliary stones from the bile duct.

• at least partially closing a distal end of the expandable device;
• delivering an energy delivery device through the lumen of the tube and the lumen of the expandable device;
• activating the energy delivery device one or more times to direct energy toward the one or more biliary stones to fragment or break up the one or more biliary stones;
• and
• moving the expandable device proximally to remove the expandable device and the one or more biliary stones from the bile duct.
