1. A full-thickness resection system, comprising:

  • a control unit coupled to a proximal end of a flexible endoscope, the control unit remaining outside of a body when a stapling head is in an operative position within a body lumen, the control unit comprising;

    an anvil actuator coupled to an anvil in the stapling head, actuation of the anvil actuator moves the anvil axially relative to a stapling mechanism in the stapling head to compress a folded full-thickness portion of lumenal tissue between the anvil and the stapling mechanism;

    a stapler actuator coupled to the stapling mechanism in the stapling head, actuation of the stapler actuator causing a rotatable staple driving cam of the stapling mechanism to drive staples through the folded lumenal tissue against the anvil; and

    a tissue cutter actuator coupled to a tissue cutter in the stapling head, actuation of the tissue cutter actuator causing the tissue cutter to resect portions of the folded lumenal tissue.
