10. A tool assembly for use with a surgical fastening device, the tool assembly comprising:
a cartridge assembly for receiving a plurality of non-deformable fasteners; and
a housing assembly disposed in juxtaposition with the cartridge assembly, the housing assembly including a recess for receiving a looped member at least partially therein,
wherein the tool assembly is configured to advance the plurality of non-deformable fasteners toward the housing assembly, wherein the plurality of non-deformable fasteners each include at least one leg extending from a backspan, wherein the portion of each leg that is farthest from the backspan of each of the plurality of fasteners is configured not to extend through the looped member.
11. The tool assembly of claim 10 , further comprising a looped member disposed at least partially within the recess of the housing assembly.
12. The tool assembly of claim 11 , wherein each leg of the plurality of fasteners extends into the same looped member.
13. The tool assembly of claim 10 , wherein the housing assembly is configured to be free from contact with the plurality of fasteners during and after ejection of the fasteners from the cartridge assembly.
14. The tool assembly of claim 10 , wherein the recess is oriented substantially parallel to the backspan of each of the plurality of fasteners.
15. The tool assembly of claim 14 , wherein the recess includes at least one cut-out extending longitudinally therein, the cut-out being configured to accommodate a portion of the legs of the fasteners.
16. The tool assembly of claim 10 , wherein the cartridge assembly includes a plurality of longitudinally-extending channels for receiving the plurality of fasteners.
17. A surgical apparatus for applying tissue fasteners, comprising:
a handle assembly;
an elongated body extending from the handle assembly and defining a longitudinal axis; and
a tool assembly including a cartridge assembly configured to receive a plurality of fasteners, and a housing assembly disposed in juxtaposed relation to the cartridge assembly, the housing assembly including a recess configured to receive a looped member at least partially therein, the recess being disposed substantially parallel to the longitudinal axis, the tool assembly being configured to advance the plurality of fasteners toward the recess of the housing assembly, and wherein each of the plurality of fasteners includes a backspan extending substantially parallel to the longitudinal axis and at least two legs depending therefrom:
wherein the recess includes at least one cut-out extending longitudinally therein, the cut-out being configured to accommodate a portion of the legs of the fasteners.
18. A tool assembly for use with a surgical fastening device, the tool assembly comprising:
a cartridge assembly for receiving a plurality of fasteners; and
a housing assembly disposed in juxtaposition with the cartridge assembly, the housing assembly including a recess for receiving a looped member at least partially therein,
wherein the tool assembly is configured to advance the plurality of fasteners toward the housing assembly, wherein the plurality of fasteners each include at least one leg extending from a backspan, wherein the portion of each leg that is farthest from the backspan of each of the plurality of fasteners is configured not to extend through the looped member;
wherein the housing assembly is configured to be free from contact with the plurality of fasteners during and after ejection of the fasteners from the cartridge assembly.
19. A tool assembly for use with a surgical fastening device, the tool assembly comprising:
a cartridge assembly for receiving a plurality of fasteners; and
a housing assembly disposed in juxtaposition with the cartridge assembly, the housing assembly including a recess for receiving a looped member at least partially therein,
wherein the tool assembly is configured to advance the plurality of fasteners toward the housing assembly, wherein the plurality of fasteners each include at least one leg extending from a backspan, wherein the portion of each leg that is farthest from the backspan of each of the plurality of fasteners is configured not to extend through the looped member;
