Endoscopic apparatus and method

A method of performing an operative procedure with an endoscopic device having a distal assembly including a tube, comprising:

• loading the endoscopic device into a channel of an endoscope, wherein the endoscope includes a plurality of channels, each of the plurality of channels extending from a proximal end of the endoscope to a distal end of the endoscope;
• inserting the endoscope and the endoscopic device into a body while the distal assembly is exterior the channel and is in a closed configuration with a profile larger than a diameter of the channel of the endoscope;
• positioning the distal assembly proximate an operative site;
• and
• activating the distal assembly to perform the operative procedure by opening and closing the distal assembly by actuating an elongate member, the elongate member including an elongate lumen within the elongate member and extending from a proximal end to a distal end of the elongate member,
• wherein the elongate member moves axially relative to the tube.

• obtaining and storing a first tissue sample within the distal assembly;
• and
• obtaining and storing a second tissue sample within the distal assembly.
