a first plunger disposed within the first carrier;

a second plunger disposed within the second carrier; and

a carrier compression spring connected to the first and second carriers.

9. (Original) The fastening device of claim 8, wherein the casing comprises a base that is configured to attach or is pre-attached to a bottom portion of a distal end of a flexible endoscope defining a plurality of channels, the base attachable or pre- attached to the flexible endoscope such that the casing does not occlude a field of view of a camera, a light source, or the plurality of channels of the endoscope.

10. (Original) A surgical fastening device comprising:

a casing;

a first carrier disposed within the casing and having a distal end defining an exit opening, the first carrier configured to house a plurality of first staples or a plurality of rivets of rivet assemblies;
