Methods and apparatus for delivering tissue treatment compositions to stapled tissue
First Claim
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.

Abstract
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.
