Surgical fastening device with initiator impregnation of a matrix or buttress to improve adhesive application
First Claim
1. A surgical stapling instrument for clamping and stapling tissue comprising:
- a) a handle, first and a second opposed tissue clamping members connected to the handle, at least one of the first and a second opposed tissue clamping members movable between an open position for receiving tissue and a closed position for stapling tissue therebetween, the first clamping member including a plurality of staples disposed therein in an array, the second clamping member comprising an anvil for forming the staples;
b) a first portion of biocompatible material into which an adhesive initiator is incorporated, the first portion of biocompatible material being releasably attached to one of the first and second opposed tissue clamping members;
c) a second portion of biocompatible material into which a fluid adhesive is incorporated, the second portion of biocompatible material being releasably attached to the other of the first and second opposed tissue clamping members and wherein the fluid adhesive polymerizes when in contact with the adhesive initiator; and
d) a knife operably movable between the first and a second opposed tissue clamping members, wherein when the tissue is clamped and stapled, the knife cuts through the tissue, the first portion of biocompatible material that incorporates the adhesive initiator, and the second portion of biocompatible material that incorporates the fluid adhesive to release the adhesive, and wherein the cut provides a passage for migration of the adhesive from the second portion of material to the adhesive initiator in the first portion of material to initiate hardening of the adhesive across the cut.

Abstract
A material comprising a matrix or a buttress is impregnated with an adhesive initiator and is used with a surgical stapling device and an adhesive. The tissue and material are stapled together, and a knife in the surgical stapling device cuts the tissue and the material. The adhesive is applied across the cut and sets up or polymerizes to seals the cut when the adhesive contacts the adhesive initiator. The surgical stapling device can place the staples in a linear, arcuate, or circular array, and can anastomose luminal tissue. The methods of use can include stapling luminal tissue end to end, stapling two portions of material onto ether side of tissue, and stapling two portions of tissue onto a portion of material. Additionally, a portion of adhesive filed material can be stapled onto one side of portion of tissue and the adhesive initiator impregnated material can be stapled onto the other. Cutting the material and tissue provides a path for the adhesive across the cut, and catalyzes the adhesive from contact with the adhesive initiator.

10. A method for securing a first and a second portion of tissue together with a plurality of staples and an adhesive comprising:
-
a) placing a portion of material into which an adhesive initiator is incorporated between a first portion and a second portion of tissue; b) clamping the material incorporating the adhesive initiator and the first and second portion of tissue between a first and a second clamping member of a surgical device with at least an edge of the material exposed; c) stapling the two portions of tissue together with the portion of material incorporating the adhesive initiator therebetween with the plurality of staples in an array; and d) applying an adhesive about the at least one exposed edge of material and the two portions of tissue to initiate the adhesive through contact between the adhesive and the adhesive initiator and to secure the two portions of tissue together. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
