A surgical stapling apparatus includes a tool assembly, at least one surgical buttress, and a resilient, porous material. The tool assembly includes a cartridge assembly and an anvil assembly pivotably coupled to the cartridge assembly. The cartridge assembly includes a first tissue facing surface defining staple retaining slots. The anvil assembly includes a second tissue facing surface defining staple pockets for forming staples expelled from the staple retaining slots of the cartridge assembly. The at least one surgical buttress is releasably disposed on at least one of the first and second tissue facing surfaces. The resilient, porous material is releasably disposable between the first and second tissue facing surfaces and in contact with the at least one surgical buttress. The resilient, porous material is configured to expel a liquid therefrom upon compression thereof by an approximation of the cartridge assembly and the anvil assembly.

1. A surgical stapling apparatus, comprising: a cartridge assembly including a first tissue facing surface defining staple retaining slots;an anvil assembly pivotably coupled to the cartridge assembly and including a second tissue facing surface defining staple pockets for forming staples expelled from the staple retaining slots of the cartridge assembly;at least one surgical buttress releasably disposed on one of the first and second tissue facing surfaces; anda resilient, porous material releasably disposed between the first and second tissue facing surfaces and in contact with the at least one surgical buttress, the resilient, porous material resiliently biasing the cartridge and anvil assemblies toward a spaced apart position, wherein the resilient, porous material is configured to expel a liquid therefrom upon compression thereof by an approximation of the cartridge assembly and the anvil assembly, the resilient, porous material including a top surface and a bottom surface, a distal portion of each of the top and bottom surfaces being in abutting engagement with a respective distal portion of each of the cartridge and anvil assemblies when the cartridge and anvil assemblies are in the spaced apart position. 2. The surgical stapling apparatus of claim 1, wherein the resilient, porous material is a sponge. 3. The surgical stapling apparatus of claim 2, wherein the sponge has an oblong shape and has a first end and a second end, wherein the sponge tapers from the first end to the second end. 4. The surgical stapling apparatus of claim 1, wherein the resilient, porous material has a length equal to a length of the at least one surgical buttress and a width equal to a width of the at least one surgical buttress. 5. The surgical stapling apparatus of claim 1, wherein the resilient, porous material is sized and dimensioned to occupy a space defined between the first and second tissue facing surfaces when the cartridge and anvil assemblies are in the spaced apart position. 6. The surgical stapling apparatus of claim 1, wherein the bottom surface is in abutting engagement with the at least one surgical buttress when the cartridge and anvil assemblies are in the spaced apart position. 7. The surgical stapling apparatus of claim 1, wherein the cartridge assembly and the anvil assembly are selectively movable relative to one another from the spaced apart position, to an approximated position, wherein the cartridge assembly and the anvil assembly cooperate to grasp tissue therebetween. 8. The surgical stapling apparatus of claim 1, wherein the resilient, porous material includes a water soluble adhesive. 9. The surgical stapling apparatus of claim 1, wherein the at least one surgical buttress is secured to at least one of the anvil assembly and the cartridge assembly by at least one anchor. 10. A surgical stapling system, comprising: a tool assembly including: a cartridge assembly including a first tissue facing surface defining staple retaining slots;an anvil assembly pivotably coupled to the cartridge assembly and including a second tissue facing surface defining staple pockets for forming staples expelled from the staple retaining slots of the cartridge assembly; anda surgical buttress releasably disposed on the first tissue facing surface of the cartridge assembly; anda resilient, porous material configured to be releasably disposed between the first and second tissue facing surfaces and on top of and in contact with the surgical buttress, the resilient, porous material resiliently biasing the cartridge and anvil assemblies toward a spaced apart position, wherein the resilient, porous material is configured to expel a liquid therefrom upon compression thereof by an approximation of the cartridge assembly and the anvil assembly. 11. The surgical stapling system of claim 10, wherein the resilient, porous material is a sponge. 12. The surgical stapling system of claim 11, wherein the sponge has an oblong shape and has a first end and a second end, wherein the sponge tapers from the first end to the second end. 13. The surgical stapling system of claim 10, wherein the resilient, porous material has a length equal to a length of the surgical buttress and a width equal to a width of the surgical buttress. 14. The surgical stapling system of claim 10, wherein the resilient, porous material includes a water soluble adhesive. 15. A method of preparing a surgical stapling apparatus, the method comprising: providing a tool assembly including: a cartridge assembly having a first tissue facing surface; andan anvil assembly having a second tissue facing surface;providing at least one surgical buttress releasably secured to the first or second tissue facing surfaces;disposing a resilient, porous material between the first and second tissue facing surfaces such that the resilient, porous material is in abutting engagement with the at least one surgical buttress and resiliently biases the cartridge and anvil assemblies toward a spaced apart position, the resilient, porous material including a top surface and a bottom surface, a distal portion of each of the top and bottom surfaces being in abutting engagement with a respective distal portion of each of the cartridge and anvil assemblies when the cartridge and anvil assemblies are in the spaced apart position;wetting the resilient, porous material with a liquid; andapproximating the cartridge assembly and the anvil assembly from the spaced apart position to an approximated position to compress the resilient, porous material therebetween such that the liquid exits the resilient, porous material and contacts the at least one surgical buttress. 16. The method of claim 15, wherein the resilient, porous material is a sponge. 17. The method of claim 16, wherein the sponge has an oblong shape and has a first end and a second end, wherein the sponge tapers from the first end to the second end. 18. The method of claim 15, wherein the resilient, porous material has a length equal to a length of the at least one surgical buttress and a width equal to a width of the at least one surgical buttress. 19. The method of claim 15, wherein the resilient, porous material is sized and dimensioned to occupy a space defined between the first and second tissue facing surfaces when the cartridge and anvil assemblies are in the spaced apart position. 20. The method of claim 15, wherein the bottom surface is in abutting engagement with the at least one surgical buttress. 21.
