Surgical fastener applying device, kits and methods for endoscopic procedures
A surgical device is provided and includes a handle housing, an endoscopic assembly, and a follower assembly. The endoscopic assembly extends distally from the handle housing and includes an inner tube defining a longitudinal axis. The inner tube includes a distal portion defining a pair of opposed tines. The endoscopic assembly is configured to support a plurality of anchors at least partially therein. The follower assembly is disposed at least partially within the inner tube at a location proximal of the plurality of anchors, and includes a head and a shaft. A portion of the head is disposed between the pair of opposed tines. Actuation of the endoscopic surgical device causes rotation of the inner tube about the longitudinal axis relative to the handle housing, and causes distal advancement of the follower assembly relative to the inner tube.

6. The surgical device according to claim 4 , wherein after a predetermined amount of longitudinal movement of the shaft of the follower assembly relative to the inner tube, the proximal portion of the shaft forces the first ring distally relative to the inner tube.
7. The surgical device according to claim 4 , wherein the follower assembly includes a second ring disposed on the shaft, the second ring is longitudinally movable relative to the shaft.
8. The surgical device according to claim 7 , wherein the second ring is positionable on the distal portion of the shaft and on the proximal portion of the shaft.
9. The surgical device according to claim 7 , wherein the first ring defines a first aperture, wherein the second ring defines a second aperture, and wherein the first aperture has a different profile than the second aperture.
10. The surgical device according to claim 1 , wherein each finger of the plurality of fingers of the plate of the follower assembly is biased away from the shaft.
11. The surgical device according to claim 1 , wherein the follower assembly is movable between a first position where at least one finger of the plurality of fingers is positioned proximally of the pair of opposed tines and a second position where the at least one finger of the plurality of fingers is positioned distally of the pair of opposed tines.
12. The surgical device according to claim 11 , wherein when the follower assembly is in the second position, part of the at least one finger positioned distally of the pair of opposed tines is positioned between the pair of opposed tines.
13. The surgical device according to claim 1 , further comprising a coil disposed within the inner tube.
14. The surgical device according to claim 13 , wherein the head of the follower assembly is disposed in operative engagement with the coil.
15. The surgical device according to claim 14 , wherein the follower assembly is longitudinally movable relative to the coil.
16. The surgical device according to claim 1 , further comprising a plurality of anchors disposed at least partially within the endoscopic assembly and disposed distally of the head of the follower assembly.
17. A surgical device, comprising:
a handle housing;
an endoscopic assembly extending distally from the handle housing and including an inner tube defining a longitudinal axis, the inner tube including a distal portion defining a pair of opposed tines, the endoscopic assembly configured to support a plurality of anchors at least partially therein; and
a follower assembly disposed at least partially within the inner tube, the follower assembly including a head, a shaft, a first ring disposed on the shaft, and a second ring disposed on the shaft, wherein a portion of the head is disposed between the pair of opposed tines, wherein the first ring includes a pair of fingers, each finger of the pair of fingers of the first ring extends between the pair of opposed tines of the inner tube, wherein the second ring includes a pair of fingers, each finger of the pair of fingers of the second ring extends between the pair of opposed tines of the inner tube, and wherein the first ring and the second ring are longitudinally movable relative to the shaft, and wherein the second ring is longitudinally movable relative to the first ring,
wherein actuation of the endoscopic surgical device causes rotation of the inner tube about the longitudinal axis relative to the handle housing, and causes distal advancement of at least a portion of the follower assembly relative to the inner tube.
18. The surgical device according to claim 17 , wherein the first ring defines a first aperture, wherein the second ring defines a second aperture, and wherein the first aperture has a different profile than the second aperture.
19. The surgical device according to claim 17 , wherein the first ring is positionable on a distal portion of the shaft and is physically prevented from being positioned on a proximal portion of the shaft, and wherein the second ring is positionable on the distal portion of the shaft and on the proximal portion of the shaft.
