## Abstract

An end effector for use with a surgical apparatus. The end effector comprising a staple cartridge having a tissue contacting surface defining a central longitudinal slot and an anvil plate having a tissue contacting surface defining a central longitudinal slot. A surgical buttress releasbly disposed on the tissue contacting surfaces of each of the staple cartridge and anvil plate. An adhesive tape is disposed over the central longitudinal slot of each of the staple cartridge and anvil plate and configured retain the respective surgical buttress atop the respective tissue contacting surface.

## Claims

### Claim 1

An end effector for use with a surgical apparatus, the end effector comprising:
a staple cartridge having a tissue contacting surface defining a central longitudinal slot;
an anvil plate having a tissue contacting surface defining a central longitudinal slot;
a surgical buttress releasbly disposed on the tissue contacting surfaces of each of the staple cartridge and anvil plate; and
an adhesive member disposed over the central longitudinal slot of each of the staple cartridge and anvil plate and configured retain the respective surgical buttress atop the respective tissue contacting surface.

### Claim 2 (depends on 1)

The end effector of claim 1, wherein the surgical buttress is laser welded to the adhesive member.

### Claim 3 (depends on 2)

The end effector of claim 2, wherein the adhesive member is an adhesive tape is secured to the tissue contacting surfaces of each of the staple cartridge and anvil plate surrounding the edges of the respective central longitudinal slots.

### Claim 4 (depends on 3)

The end effector of claim 3, wherein the adhesive tape extends longitudinally between a proximal end and a distal end of the tissue contacting surfaces of each of the staple cartridge and anvil plate.

### Claim 5

A staple cartridge for use with a surgical stapling apparatus, the staple cartridge comprising:
a cartridge body including a tissue contacting surface defining a plurality of staple retaining slots and having a central longitudinal slot;
a staple disposed within each staple retaining slot of the cartridge body;
a surgical buttress releasbly disposed on the tissue contacting surfaces of the cartridge body; and
an adhesive tape disposed over the central longitudinal slot of the cartridge body and configured to retain the surgical buttress atop the tissue contacting surface of the cartridge body.

### Claim 6 (depends on 5)

The staple cartridge of claim 5, wherein the surgical buttress is laser welded to the adhesive tape.

### Claim 7 (depends on 6)

The staple cartridge of claim 6, wherein the adhesive tape is secured to the tissue contacting surface of the cartridge body surrounding the edges of the central longitudinal slot.

### Claim 8 (depends on 7)

The staple cartridge of claim 7, wherein the adhesive tape extends longitudinally between a proximal end and a distal end of the tissue contacting surface of the cartridge body.

### Claim 9

A surgical stapling apparatus, comprising:
a housing;
an end effector being secured to the housing having a staple cartridge assembly having a tissue contacting surface and an anvil assembly having a tissue contacting surface, each of the staple cartridge assembly and anvil assembly having a central longitudinal slot;
a surgical buttress releasbly disposed on the tissue contacting surfaces of each of the staple cartridge assembly and anvil assembly; and
an adhesive tape disposed over the central longitudinal slot of each of the staple cartridge assembly and anvil assembly and configured retain the respective surgical buttress atop the respective tissue contacting surface.

### Claim 10 (depends on 9)

The surgical stapling apparatus of claim 9, wherein the surgical buttress is laser welded to the respective adhesive tape.

### Claim 11 (depends on 10)

The surgical stapling apparatus of claim 10, wherein the adhesive tape is secured to the tissue contacting surfaces of each of the staple cartridge assembly and anvil assembly surrounding the edges of the respective central longitudinal slots.

### Claim 12 (depends on 11)

The surgical stapling apparatus of claim 11, wherein the adhesive tape extends longitudinally between a proximal end and a distal end of the tissue contacting surfaces of each of the staple cartridge assembly and anvil assembly.
