Abstract

An anvil assembly for a circular stapling device includes an anvil head configured to support an anvil plate thereon, a shaft extending from the anvil head and configured to selectively engage a rod member of the circular stapling device, an anvil plate operatively connected to the anvil head, wherein the anvil plate includes an inner diametral edge, and wherein the anvil plate defines a plurality of staple forming pockets therein at a location radially outward of the inner diametral edge, a recess formed in the anvil head, wherein the recess is defined by the inner diametral edge of the anvil plate and a rear surface of the anvil head, and a wound treatment material disposed substantially within the recess.

Claims

1. A surgical stapling device, comprising:

a handle portion;

an elongate body portion; and

a head portion located at the distal end of the body portion, the head portion including an anvil assembly, a staple cartridge assembly and a knife blade, the staple cartridge assembly having an annular array of staples, the anvil assembly being connected to the body portion along a shaft, the anvil assembly including;

an anvil plate defining a plurality of staple forming pockets therein and a recess; and

a wound treatment material disposed substantially within the recess.

2. The surgical stapling device of claim 1, wherein the wound treatment material is contained in at least one wound treatment material delivery pouch.

3. The surgical stapling device of claim 2, wherein the wound treatment material delivered pouch includes a plurality of compartments.

4. The surgical stapling device of claim 1, wherein the wound treatment material is contained in a pair of stacked wound treatment material delivery pouches.

5. The surgical stapling device of claim 4, wherein the pair of stacked wound treatment material delivery pouches are axially aligned with the knife blade.

6. The surgical stapling device of claim 1, wherein the wound treatment is contained in at least on C-shaped pouch.

7. The surgical stapling device of claim 6, wherein the wound treatment material is contained in a pair of C-shaped pouches.

8. The surgical stapling device of claim 7, wherein the C-shaped pouches are disposed on either side of the shaft.

9. The surgical stapling device of claim 7, wherein the wound treatment material within a first of the pair of C-shaped pouches is different than the wound treatment material within the other of the pair of C-shaped pouches.
