A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a removable cartridge. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further includes an agent. The firing bar is operable to assist with releasing the agent onto a severed line of tissue when the firing bar is advanced.

1. A surgical instrument apparatus comprising: (a) a handle portion;(b) a shaft housing a firing bar;(c) an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft; and(d) a removable
1. A surgical instrument apparatus comprising: (a) a handle portion;(b) a shaft housing a firing bar;(c) an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft; and(d) a removable cartridge, wherein the lower jaw is configured to receive the cartridge, the cartridge comprising: (i) a housing,(ii) a plurality of staples disposed in the housing,(iii) a deck disposed over the plurality of staples, the deck defining a plurality of apertures, each aperture being substantially disposed over each staple, and(iv) a biocompatible material, wherein the firing bar is operable to apply the biocompatible material to tissue while the stapling and severing assembly simultaneously severs and drives staples into the tissue, wherein the firing bar includes a notch configured to receive the biocompatible material. 2. The apparatus of claim 1, wherein the biocompatible material is disposed on or beneath the deck of the cartridge at a proximal end of the cartridge. 3. The apparatus of claim 1, wherein the biocompatible material is wrapped about a pair of spools. 4. The apparatus of claim 3, wherein the spools are resiliently biased. 5. The apparatus of claim 3, wherein the biocompatible material wrapped about the spools is configured to advance when the firing bar advances through a slot of the deck of the cartridge in response to the longitudinal closing motion produced by the handle portion and the shaft. 6. The apparatus of claim 5, further comprising a pair of knives positioned at a distal end of the slot of the deck of the cartridge. 7. The apparatus of claim 6, wherein the knives are configured to sever the biocompatible material when the biocompatible material reaches the distal end of the slot. 8. The apparatus of claim 1, wherein when the biocompatible material comprises a tape, wherein a notch in the firing bar is configured to receive the tape. 9. The apparatus of claim 1, wherein an area proximal to a leading edge of the firing bar is configured to receive the biocompatible material. 10. The apparatus of claim 9, further comprising a pair of rollers configured to release the biocompatible material onto notches on side surfaces of the firing bar when the firing bar advances distally. 11. The apparatus of claim 9, further comprising an ampoule housing the biocompatible material, wherein the leading edge of the firing bar is configured to sever the ampoule when the firing bar advances distally to release the biocompatible material into notches on side surfaces of the firing bar. 12. The apparatus of claim 9, wherein the biocompatible material comprises a spring-biased gel block, wherein the leading edge of the firing bar is configured to advance distally past the gel block when the firing bar advances distally to release the biocompatible material into notches on side surfaces of the firing bar. 13. The apparatus of claim 12, wherein the spring-biased gel block comprises a pair of blocks resiliently biased against opposite sides of the firing bar. 14. The apparatus of claim 12, wherein the spring-biased gel block comprises a severable block, and wherein the leading edge of the firing bar is configured to advance distally to sever the severable block into a pair of block portions such that the biocompatible material is released from severed areas of the pair of block portions into notches on side surfaces of the firing bar. 15. A method of releasing material from a surgical instrument, the surgical instrument including an end effector, a handle portion, and a shaft housing a firing bar, the end effector including a lower jaw and an anvil, the lower jaw being configured to receive a removable cartridge, the cartridge including a deck having a vertical slot, the instrument further including a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft, the stapling and severing assembly including the firing bar, the method comprising the steps of: (a) inserting the cartridge comprising a biocompatible material in the lower jaw of the end effector such that the biocompatible material is retained within a notch in the firing bar when the firing bar is in a first position; and(b) producing the longitudinal closing motion to advance the firing bar of the stapling and severing assembly through the vertical slot of the deck of the cartridge to a second position, such that the advancement of the firing bar concurrently advances the retained biocompatible material. 16. The method of claim 15, further comprising the step of: (a) severing the advanced retained biocompatible material by a pair of knives positioned at a distal end of the vertical slot of the deck of the cartridge. 17. The method of claim 16, further comprising the step of: (a) urging the firing bar to the first position upon removal of the longitudinal closing motion produced by the handle portion and the shaft. 18. A surgical instrument comprising: (a) a handle portion and a shaft, the shaft housing a firing bar;(b) a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft,(c) a staple cartridge;(d) an end effector connected to the handle portion, the end effector comprising an anvil and a lower jaw, the lower jaw being configured to receive the staple cartridge;(e) a plurality of staples disposed in a housing of the staple cartridge, the anvil being configured to form the staples in response to the longitudinal closing motion; and(f) a biocompatible material, wherein the biocompatible material is disposed on or in the staple cartridge;wherein the firing bar comprises a plurality of notches, wherein the firing bar is operable to move between the anvil and the cartridge, and wherein the notches are configured to retain portions of the biocompatible material. 19. The instrument of claim 18, wherein the firing bar is operable to sever the biocompatible material, and wherein the notches are configured to retain portions of the severed material, wherein the biocompatible material comprises one or more of adhesives, sealants, healing agents, or antimicrobials.
