The first beam 74 is engaged with the anvil 32 and the second beam 76 is engaged with the cartridge assembly 30 such that movement of the working member 66 from the retracted position to the advanced position in relation to the cartridge assembly 30 and the anvil 32 moves the tool assembly 16 from its open position to its clamped position to define a maximum tissue gap between the cartridge assembly 30 and the anvil 32. In aspects of the disclosure, the vertical strut 78 of the working end 66 of the drive assembly 60 includes or supports a knife blade 80. The '139 Patent describes operation of the working end of a suitable drive assembly in further detail. 7 Date Recue/Date Received 2021-06-23 [0043] The tool assembly 16 of the stapling device 10 includes an actuation sled 82 that is engaged with the distal portion of the drive beam 64 of the drive assembly 60 and is received within the cartridge body 42. In aspects of the disclosure, the actuation sled 82 is fixedly secured to the working end 66 of the drive assembly 60 such that movement of the drive assembly 64 between its retracted and advanced positions causes movement of the actuation sled 82 within the cartridge assembly 30 between retracted and advanced positions. Alternately, the actuation sled 82 can be in abutting relation to the working end 66 of the drive assembly 60 such that movement of the drive assembly between its retracted and advanced positions causes movement of the actuation sled 82 to its advanced position but does not retract the actuation sled 82 from its advanced position. [0044] When the drive assembly 60 is moved from its retracted position to its advanced position, the actuation sled 82 is moved from its retracted position to its advanced position. As the actuation sled 82 moves towards its advanced position, the actuation sled 82 moves into sequential engagement with the pushers 46 to urge the pushers 46 upwardly as viewed in FIG. 3 to eject the staples 44 from the staple receiving pockets 56 of the cartridge body 42. The '139 Patent describes engagement between the actuation sled 82 and the pushers 46 in detail. [0045] FIGS. 4 and 5 illustrate the distal portion 64b of the drive assembly 60 and the actuation sled 82 in further detail. In aspects of the disclosure, the actuation sled 82 includes spaced ramps 90 that are positioned to engage the pushers 46 as the actuation sled 82 is moved through the staple cartridge 40 to move or lift the pushers 46 within the cartridge body 42 of the staple cartridge 40 when the stapling device 10 (FIG. 1) is fired. The spaced ramps 90 define channels 92 that receive the pushers 46 when the actuation sled 82 moves from its retracted position to its advanced position. Each of the spaced ramps 90 includes one or more protrusions 94 that extend transversely from an upper end of the spaced ramps 90 into the channels 92. The actuation sled 82 also includes a central guide member 96 that centrally locates the actuation sled 82 within the cartridge body 42 as the actuation sled 82 moves longitudinally within the cartridge body 42 of the staple cartridge 40. The central guide member 96 also includes protrusions 94 that extend into the channels 92 through which the pushers 46 move to eject the staples 44 from the cartridge body 42. [0046] FIGS. 6-8 illustrate the staples 44 and the pushers 46 in further detail. Each of the pushers 46 includes a body 100 that includes a staple supporting surface 102 and tubular needles 8 Date Recue/Date Received 2021-06-23 104 that project from the body 100 towards the tissue engaging surface 52 of the cartridge body 42. In aspects of the disclosure, the needles 104 are in the form of nanoneedles or microneedles. Nanoneedles are small scale devices that overcome resistance during drug diffusion by creating conduits of small dimension through bio membranes. The needles 104 extend through the body 42 of the pushers 46 and communicate with a reservoir 106 that is defined by the body 100 of the respective pusher 46. The reservoir 106 is filled with PFC solution 108. [0047] Each of the staples 44 includes a back span 110 and legs 112 that extend from each end of the of the back span 110. Each of the legs 112 includes a tapered tip 112a for piercing tissue "T" (FIG. 9). The back span 110 of each of the staples 44 is supported on the staple supporting surface 102 of a respective pusher 46. In aspects of the disclosure, the back span 110 of each of the staples 44 is cylindrical and the staple supporting surface 102 of each of the pushers 44 defines a cylindrical concavity. Alternately, other configurations are envisioned. In some aspects of the disclosure, when the back spans 110 of the staples 44 are received on the staple supporting surfaces 102 of the pushers 46, the needles 104 have a height that is greater than the diameter of the back spans 110 and extend above the back spans 110 as viewed in FIG. 7. [0048] As illustrated, the pushers 46 are coupled together with cam members 120. Each of the cam members 120 includes a tapered bottom surface 120a as viewed in FIG. 6 that is aligned with one of the spaced ramps 90 (FIG. 5) of the actuation sled 82 when the staple cartridge 40 is assembled. As such, the pushers 44 are aligned with the channels 92 of the actuation sled 82. Although it is illustrated that three pushers 44 are coupled together with two cam members 120 and move in unison, it is envisioned that the pushers 44 need not be coupled to each other, and that any number of pushers 46 can be coupled together and move in unison, e.g., two, three, four, etc. [0049] FIGS. 9-13 illustrate the tool assembly 16 with the tool assembly 16 clamped about tissue "T". FIGS. 9 and 10 illustrate the tool assembly 16 in a clamped position about tissue prior to firing the stapling device 10 (FIG. 1). In this position, the pushers 46 have not been engaged by the actuation sled 82 (FIG. 3) and are in their lowest or retracted position within the cartridge body 42 of the staple cartridge 40. As illustrated, the staples 44 are recessed within the staple receiving pockets 56 (FIG. 3) of the cartridge body 42 beneath the tissue "T" and the needles 104 extend towards the anvil 32 to a position above the back span 110. 9 Date Recue/Date Received 2021-06-23 [0050] FIGS. 11-13 illustrate the tool assembly 16 as the stapling device 10 (FIG. 1) is fired. When the stapling device 10 (FIG. 1) is fired, the actuation sled 82 is moved through the cartridge body 42 of the staple cartridge 40 in response to movement of the drive assembly 60 from its retracted position to its advanced position. As the actuation sled 82 is advanced within the cartridge body 42, the ramps 90 (FIG. 4) of the actuation sled 82 sequentially engage the cam members 120 (FIG. 11) of the pushers 46 to lift the pushers 46 within the staple receiving pockets 56 (FIG. 3) of the cartridge body 42 of the staple cartridge 40 in the direction of arrows "A" in FIG. 11 to eject the staples 44 from the staple receiving pockets 56 into the anvil 32 (FIG. 11). Because the height of the needles 104 is greater than the diameter of the back span 110 of the staples 44, the needles 104 pierce the tissue "T" as the staples 44 are formed against the anvil 32. As the actuation sled 82 passes by the pushers 46, the protrusions 94 (FIG. 5) on the upper ends of the ramps 90 and central guide member 96 of the actuation sled 82 (which extend laterally into the channels 92 defined between the spaced ramps 90 of the actuation sled 82) engage side walls of the body 100 of the pushers 46. Engagement of the protrusions 94 with the side walls of the body 100 of the pushers 46 forces the PFC solution 108 from the reservoir 106 through the needles 104 into the tissue "T" adjacent a staple line formed by the rows of staples 44 (FIG. 13). It is noted that where the actuation sled 82 is fixedly coupled to the working end 66 of the drive assembly 60, the protrusions on the actuation sled 82 will engage each of the pushers 46 a second time to force more PFC solution 108 from the reservoir 106 through the needles 104 into the tissue "T" as the actuation sled 82 is returned from its advanced position to its retracted position. [0051] When the PFC solution 108 is injected into the tissue, the PFC solution 108 delivers oxygen to ischemic regions of the staple line that may have been compromised during the surgical procedure to minimize any likelihood of tissue necrosis. The delivery of the PFC solution is particularly beneficial in surgical procedures where there is a limited amount of tissue for stapling. [0052] Although this disclosure illustrates the use of PFC solution in a linear type stapler, it is envisioned that the use of PFC could be incorporated into any stapling device for stapling tissue including circular stapling devices. In a circular stapling device, there may only be a single pusher and the protrusions could be formed on a stationary portion of a shell assembly of the circular stapling device. It is also envisioned that the reservoir for storing the PFC solution need Date Recue/Date Received 2021-06-23 not be in the pushers but could be in any portion of the cartridge assembly including the cartridge body. Further, although the PFC solution is disclosed as being delivered via interaction of the actuation sled and the pushers, it is envisioned that the PFC solution could be delivered via a number of different devices that function in response to firing of the stapling device or independently thereof. Persons skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary aspects of the disclosure. It is envisioned that the elements and features illustrated or described in connection with one exemplary aspects of the disclosure may be combined with the elements and features of another without departing from the scope of the disclosure. As well, one skilled in the art will appreciate further features and advantages of the disclosure based on the above-described aspects of the disclosure. Accordingly, the disclosure is not to be limited by what has been particularly shown and described, except as indicated by the appended claims. 1 1 Date Recue/Date Received 2021-06-23 _õõ.....õ ilk c.. _ \ \ \ \ \ 4tt c., ¨ = cb ¨ w _ c7. ----- , cq \\ I \ , , i 1 " i \ 'N / / 7 ¨ _____ - - Date Recue/Date Received 2021-06-23 (1* 16 \ le* 01 32 , -7, /-4=- 4al .v I" ,=,--- .,-- 34 ,------, ,- ( 0 - , v O$ 11 iv 30 FIG. 2 LCC, Date Recue/Date Received 2021-06-23 IL VD CV CJO CCI = µ - T.. , i..... , \ t \ CO 4 \ =cl- \ \ , ' \ 1 \ 1 \ \ ¨ I - 1.1 \ ____________________ Awir= 4 I \ co 0, _ .... _______________________________________ .4- \ \ '' 1 i a - ¨ I. n co ..... .,õ iiii õ , 1 ___ J. 1 \ , _ ______________________ _-=11,1,1% 1 , , , c..., , ___________________________ . ---..-1-1 ' t 1 -iii i - , , cc, cr, õ 1 - --as a ,y,,,,,, Ai., __ . ., it Vi E 1 _______________________ . __ : _____________________________ .. i_ _ii., *..-. _..õ,..1 \ 5 t ,,i I 1 , \ \ iõ , t - ___________________________________ t 1 ________________________________ 3 . _____________________________ ....,... ,.... __,Ii-- .....õ, 1) , , ___________________ ,= ___ , .9 CO -lillµ =Cl- C.," i t; i 1 - --Z-'= = CO oe i t 1 li.. - _______________________________ r ......\ _ . ,.... . ..... , CV \ rt, \ t ¨....... \ µi -4- = 89,7 .."".........______, Date Recue/Date Received 2021-06-23 74 78 94 t-------- AP1-_,...0%-%- ------------ 96 **** / = 3,,-=,-,4111-1.1 1 78 64h wfr.5 --------- 92 76 92 r 82 90 FIG. 4 74 78 94 96 )111µ Li as.

Applicants may wish to consider the filing of an international application under the Patent Cooperation Treaty (PCT). An international (PCT) application generally has the same effect as a regular national patent application in each PCT-member country. The PCT process simplifies the filing of patent applications on the same invention in member countries, but does not result in a grant of "an international patent" and does not eliminate the need of applicants to file additional documents and fees in countries where patent protection is desired. Almost every country has its own patent law, and a person desiring a patent in a particular country must make an application for patent in that country in accordance with its particular laws. Since the laws of many countries differ in various respects from the patent law of the United States, applicants are advised to seek guidance from specific foreign countries to ensure that patent rights are not lost prematurely. Applicants also are advised that in the case of inventions made in the United States, the Director of the USPTO must issue a license before applicants can apply for a patent in a foreign country. The filing of a U.S. patent application serves as a request for a foreign filing license. The application's filing receipt contains further information and guidance as to the status of applicant's license for foreign filing. Applicants may wish to consult the USPTO booklet, "General Information Concerning Patents" (specifically, the section entitled "Treaties and Foreign Patents") for more information on timeframes and deadlines for filing foreign patent applications. The guide is available either by contacting the USPTO Contact Center at 800-786-9199, or it can be viewed on the USPTO website at http://www.uspto.gov/web/offices/pac/doc/general/index.html. For information on preventing theft of your intellectual property (patents, trademarks and copyrights), you may wish to consult the U.S. Government website, http://www.stopfakes.gov. Part of a Department of Commerce initiative, this website includes self-help "toolkits" giving innovators guidance on how to protect intellectual property in specific countries such as China, Korea and Mexico. For questions regarding patent enforcement issues, applicants may call the U.S. Government hotline at 1-866-999-HALT (1-866-999-4258). page 2 of 3 Date Recue/Date Received 2021-06-23
