Abstract

Embodiments include an end effector including an anvil, the anvil having an anvil face, an anvil blade channel defined by the anvil face, a first pocket row of first row staple pockets, a second pocket row of second row staple pockets, a third pocket row of third row staple pockets, a fourth pocket row of fourth row staple pockets, a fifth pocket row of fifth row staple pockets, a sixth pocket row of sixth row staple pockets, a cartridge having a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples, and a blade, the blade having a cutting edge, where the blade is movable from a first position at a distal end of the cartridge to a second position at a proximal end of the cartridge.

First claim

What is claimed is:

1 . A buttress configured for use with an end effector for stapling and cutting an anatomical structure, the buttress comprising:
(a) a planar section of material having:
(i) a first portion configured to contact an anvil of the end effector; and
(ii) a second portion configured to contact a cartridge of the end effector; and
(b) a first removable portion that releasably couples the first portion to the second portion, wherein movement of the first removable portion in a first inward direction causes at least one adhesive-bearing member to move radially inward and contact the end effector.

2 . The buttress of claim 1 , wherein the at least one adhesive-bearing member includes a backing material, wherein the backing material can be removed to expose an adhesive portion on the at least one adhesive-bearing member.

3 . The buttress of claim 2 , further comprising at least one thread coupled to the backing material, wherein the at least one thread is configured to remove the backing material from the at least one adhesive-bearing member and expose the adhesive portion.

4 . The buttress of claim 2 , wherein the adhesive portion adheres to a first side of the anvil, a second side of the anvil, a first side of the cartridge, or a second side of the cartridge, when the at least one adhesive-bearing member moves radially inward.

5 . The buttress of claim of claim 1 , wherein the first removable portion is pliable.

6 . The buttress of claim 1 , wherein the first portion of the planar section of material covers at least a portion of a face of the anvil, and wherein the second portion of the planar section of material covers at least a portion of a face of the cartridge.

7 . The buttress of claim 1 , wherein the planar section of material is formed from a bioabsorbable material.

8 . The buttress of claim 1 , further comprising a second removable portion opposite the first removable portion, wherein movement of the second removable portion in a second inward direction causes at least a second adhesive-bearing member to move radially inward and contact the end effector.

9 . A buttress configured for use with an end effector for stapling and cutting an anatomical structure, the buttress comprising:
(a) a planar section of material having:
(i) a first portion configured to contact an anvil of the end effector; and
(ii) a second portion configured to contact a cartridge of the end effector;
(b) a first removable portion, wherein movement of the first removable portion in a first inward direction causes a first adhesive-bearing members to move radially inward and contact a first side of the end effector; (c) a second removable portion opposite the first removable portion, wherein movement of the second removable portion in a second inward direction causes a second adhesive-bearing members to move radially inward and contact a second side of the end effector.

10 . The buttress of claim 9 , wherein the first removable portion and the second removable portion releasably couple the first portion to the second portion.

11 . The buttress of claim 9 , wherein the first and second adhesive-bearing members each include a backing material, wherein the backing material can be removed to expose an adhesive portion on each of the first and second adhesive-bearing members.

12 . The buttress of claim 11 , further comprising at least one thread coupled to the backing material of the first and second adhesive-bearing members, wherein the at least one thread is configured to remove the backing material from the first and second adhesive-bearing members and expose the adhesive portions.

13 . The buttress of claim 11 , wherein the adhesive portion of the first adhesive-bearing member adheres to a first side of the anvil or a first side of the cartridge, and wherein the adhesive portion of the second adhesive-bearing member adheres to a second side of the anvil or a second side of the cartridge.

14 . The buttress of claim of claim 9 , wherein the first and second removable portions are pliable.

15 . The buttress of claim 9 , wherein the first portion of the planar section of material covers at least a portion of a face of the anvil, and wherein the second portion of the planar section of material covers at least a portion of a face of the cartridge.

16 . A buttress configured for use with an end effector for stapling and cutting an anatomical structure, the buttress comprising:
(a) a planar section of material having:
(i) a first portion configured to contact an anvil face of the end effector;
(ii) a second portion configured to contact a cartridge face of the end effector;
(iii) a first set of adhesive-bearing members; and
(iv) a second set of adhesive-bearing members;
(b) a first removable portion, wherein movement of the first removable portion in a first inward direction causes the first set of adhesive-bearing members to each move radially inward and contact a first side of the end effector; and (c) a second removable portion opposite the first removable portion, wherein movement of the second removable portion in a second inward direction causes the second set of adhesive-bearing members to each move radially inward and contact a second side of the end effector.

17 . The buttress of claim 16 , wherein the first removable portion and the second removable portion releasably couple the first portion to the second portion.

18 . The buttress of claim 16 , wherein:
(a) the first set of adhesive-bearing members each include a backing material and an adhesive portion, wherein the backing material on each of the first set of adhesive-bearing members can be removed to expose the adhesive portions; and (b) the second set of adhesive-bearing members each include a backing material and an adhesive portion, wherein the backing material on each of the second set of adhesive-bearing members can be removed to expose the adhesive portions.

19 . The buttress of claim 18 , further comprising at least one thread, wherein the at least one thread is configured to remove the backing materials from the first and second sets of adhesive-bearing members to expose the adhesive portions.

20 . The buttress of claim 16 , wherein the first and second removable portions are pliable.
