The present invention is directed to a full-thickness resection system comprising a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism includes an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another. A position adjusting mechanism is provided for moving the anvil and the stapling head relative to one another.An integrated surgical retainer for use in the full thickness resectioning device is described. The integrated surgical staple retainer comprises a calibrating portion, a retaining portion, and a grasping portion. The calibrating portion defines a circular opening which has a diameter substantially equal to a diameter of a working channel of the full thickness resectioning device. The retaining portion has a lower surface adapted to limit movement of the surgical staples in the full thickness resectioning device and is adjacent to the calibrating portion of the integrated surgical staple retainer.

An integrated surgical staple retainer of a FTRD, comprising:a calibrating portion defining a circular opening, the circular opening having a diameter substantially equal to a diameter of a working channel of the FTRD; and a retaining portion having a surface adapted to limit movement of the surg
1. An integrated surgical staple retainer of a FTRD, comprising:a calibrating portion defining a circular opening, the circular opening having a diameter substantially equal to a diameter of a working channel of the FTRD; and a retaining portion having a surface adapted to limit movement of the surgical staples held in the FTRD, the retaining portion being adjacent to the calibrating portion; and a grasping portion adjacent to the retaining portion. 2. The integrated surgical staple retainer according to claim 1, further comprising:a positioning element disposed on the retaining portion, the positioning element holding the integrated surgical staple retainer in position relative to the FTRD. 3. The integrated surgical staple retainer according to claim 1, wherein the positioning element comprises a plurality of protrusions.4. The integrated surgical staple retainer according to claim 1, wherein the calibrating portion is adapted to be placed in a cavity formed by a head assembly of the FTRD.5. The integrated surgical staple retainer according to claim 1, wherein the retaining portion is adapted to be placed between a proximal housing and an anvil member of the FTRD.6. The integrated surgical staple retainer according to claim 5, wherein the retaining portion is adapted to be placed between staple slits of a proximal housing of the FTRD and staple forming grooves of an anvil member of the FTRD.7. The surgical integrated surgical staple retainer according to claim 1, wherein the retaining portion is adapted to immobilize the staples held in the FTRD.8. A staple retaining device for an FTRD, comprising:a retaining portion removably insertable in a gap formed between an anvil and a proximal housing of the FTRD; retaining surfaces of the retaining portion adapted to cap staple slits of the proximal housing; a grasping element of the retaining portion; and a calibrating element of the retaining portion. 9. The staple retaining device according to claim 8, further comprising at least one protrusion extending from the retaining portion, adapted to engage the anvil to maintain the retaining portion in the gap.10. The staple retaining device according to claim 9, wherein a height of the at least one protrusion is greater than a minimum size of the gap, and smaller than a maximum size of the gap.11. The staple retaining device according to claim 9, wherein the at least one protrusion comprises ridges adapted to engage staple forming grooves of the anvil.12. The staple retaining device according to claim 8, wherein the grasping element comprises a tab for manually inserting and removing the retaining portion from the gap.13. The staple retaining device according to claim 8, wherein the calibrating element comprises a gage for measuring dimensions of an endoscope.14. The staple retaining device according to claim 8, wherein the calibrating element comprises an opening sized to replicate a minimum size of a lumen of the FTRD.15. The staple retaining device according to claim 14, wherein the calibrating element is formed on a region of the retaining portion that is not insertable in the gap.16. The staple retaining device according to claim 14, wherein the calibrating element is formed on a region of the retaining portion that is insertable in the gap.17. A packaging for an FTRD, comprising:an FTRD having an anvil and a proximal housing; a staple retaining device disposed in a gap between the anvil and the proximal housing; surfaces of the staple retaining device adapted to prevent removal of staples from the proximal housing; and a calibrating portion integral with the staple retaining device. 18. The packaging according to claim 17, further comprising a grasping portion of the staple retaining device for manually removing the device from the gap.19. The packaging according to claim 17, wherein the calibrating portion is dimensioned to replicate a minimal dimension of a lumen of the FTRD.20. The packaging according to claim 17, further comprising projections of the staple retaining device adapted to engage at least one of the anvil and the proximal housing.
