Abstract
Disclosed herein are devices and methods for introducing a plurality of instruments to a target site through a working channel. The working channel can include a surface adapted to guide one or more instruments into select positions. The working channel can be defined by a portion of a guide tube or tip that may be coupled with an endoscope.

A method of directing instruments to a target site of a patient, comprising:
- introducing a first instrument into a lumen of a tube, wherein the lumen is partially defined by a movable surface that is movable relative to other internal surfaces defining the lumen, the movable surface being positioned proximate to a distal end of the lumen;
- positioning a distal end of the first instrument distal to the movable surface;
- introducing a second instrument into the lumen while the first instrument is disposed in the lumen;
- causing the second instrument to contact the movable surface to move the movable surface;
- and
- positioning a distal end of the second instrument distal to the movable surface.

A method of directing instruments to a target site of a patient, comprising:
- introducing a first instrument into a proximal end of a lumen of a tube, wherein the lumen is partially defined by a movable surface that is movable relative to other internal surfaces defining the lumen, the movable surface being positioned proximate to a distal end of the lumen, and wherein the movable surface extends from a first end to a second end, the second end being distal and radially inward of the first end;
- moving a distal end of the first instrument past the movable surface;
- introducing a second instrument into the proximal end of the lumen;
- and
- moving the second instrument into contact with the movable surface to cause movement of the movable surface.

A method of directing instruments to a target site of a patient, comprising:
- introducing a first instrument into a lumen of a tube, wherein the lumen is partially defined by a surface movable between a first configuration and a second configuration relative to a wall of the tube;
- moving a distal end of the first instrument past the surface;
- introducing a second instrument into the lumen;
- and
- moving a distal end of the second instrument into contact with the surface to cause movement of the surface from the first configuration to the second configuration.
