A surgical stapler includes first and second tissue clamping members and a reservoir configured to hold a tissue treatment composition. The first tissue clamping member is configured to receive a plurality of staples. The second tissue clamping member comprises an anvil configured to form the staples. The reservoir may be provided in a handle portion of the surgical stapler, and a fluid conduit may be used to communicate the tissue treatment composition from the reservoir. An end effector lumen may selectively communicate with the fluid conduit. The lumen may also be in communication with openings to further communicate the tissue treatment composition to tissue or to a scaffold material positioned adjacent to tissue. A reservoir may alternatively be provided in one of the clamping members. A knife member may pierce a housing defining the reservoir, and a resilient member may then urge a tissue treatment composition from the housing.

1. A surgical stapling instrument for stapling tissue, comprising: (a) a handle portion;(b) first and second opposed clamping members coupled with the handle portion, at least one of the clamping members being movable between an open position for receiving tissue and a closed position for stapling tissue between the clamping members, wherein the first clamping member is configured to receive a plurality of staples, wherein the second clamping member comprises an anvil for forming the staples;(c) a reservoir configured to hold a tissue treatment composition, wherein the reservoir includes a mincing chamber having a mincer for mincing tissue fragments of a tissue treatment composition contained in the reservoir; and(d) a fluid conduit for selectively delivering a tissue treatment composition from the reservoir to a region between the first and second clamping members. 2. The surgical stapling instrument of claim 1, further comprising a shaft extending between the handle portion and the first and second clamping members, wherein the reservoir is provided in said handle portion, wherein the fluid conduit extends from the reservoir through the interior of the shaft. 3. The surgical stapling instrument of claim 1, further comprising an actuator for causing the mincer to mince tissue fragments within the reservoir. 4. The surgical stapling instrument of claim 1, further comprising a biocompatible scaffold positionable between the first and second clamping members, wherein the scaffold is configured to receive a tissue treatment composition delivered to the region between the clamping members. 5. The surgical stapling instrument of claim 4, further comprising an end effector shaft extending between the first and second clamping members, wherein the scaffold comprises an annular disc positionable between the first and second clamping members on the shaft. 6. The surgical stapling instrument of claim 1, further comprising an end effector shaft extending between the first and second clamping members, wherein the end effector shaft includes a bore extending through at least a portion of the end effector shaft and at least one aperture communicating between the bore and the exterior of the end effector shaft, wherein the bore is configured for selective fluid communication with the fluid conduit such that, when the bore is in fluid communication with the fluid conduit, a fluid treatment composition urged through the fluid conduit is expelled from the at least one aperture to a region between the first and second clamping members. 7. The surgical stapling instrument of claim 6, wherein the end effector shaft comprises: (i) an anvil shaft extending proximally away from the second clamping member, wherein a first part of the bore is formed through the anvil shaft, and(ii) a post member extending distally away from the first clamping member, wherein the second part of the bore is formed through the post member. 8. The surgical stapling instrument of claim 7, wherein the anvil shaft is configured to insertingly receive the post member. 9. The surgical stapling instrument of claim 7, wherein the post member is operably movable within the first clamping member to selectively place the bore in fluid communication with the fluid conduit. 10. The surgical stapling instrument of claim 6, wherein the bore and the fluid conduit are configured and positioned such that the bore is in fluid communication with the fluid conduit when the first and second clamping members are at the closed position.
