Methods of using wound treatment infused sutures

1. A method of joining tissue, the method comprising:

providing an anastomosis instrument including a staple cartridge assembly and a body portion;

providing an anvil assembly including an anvil head and an anvil rod extending from the anvil head;

providing a surgical suture including a cylindrical wall defining a lumen therethrough and a wound treatment material contained within the lumen of the surgical suture, the surgical suture configured to rupture and release the wound treatment material when subjected to a pressure;

advancing the anvil assembly with respect to the body portion of the anastomosis instrument;

disposing a first tissue section around the anvil assembly and disposing a second tissue section around the staple cartridge assembly so that the first tissue section and the second tissue section are interposed between the anvil head and the staple cartridge assembly;

disposing the surgical suture between the anvil head and the staple cartridge assembly, and at least partially across a tissue contacting surface of the staple cartridge assembly; and

approximating the anvil head and the body portion to create pressure between the anvil head and the staple cartridge assembly and onto the surgical suture, to rupture the surgical suture and release the wound treatment material contained therein, thereby contacting the first and second tissue sections with the wound treatment material of the surgical suture.

2. The method of claim 1 , further comprising firing the anastomosis instrument to mechanically secure the first and second tissue sections.

3. The method of claim 1 , further comprising connecting the anvil assembly to the body portion of the anastomosis instrument before approximating the anvil head and the body portion.

4. The method of claim 1 , wherein the disposing of the surgical suture between the anvil head and the staple cartridge assembly further includes securing the first tissue section about the anvil assembly with the surgical suture.

5. The method of claim 4 , wherein the securing of the first tissue section about the anvil assembly further includes extending the surgical suture across a staple anvil pocket of the anvil assembly.

6. A method of performing a surgical anastomosis procedure comprising:

providing a surgical stapling apparatus having a distal end;

providing an anvil assembly including an anvil head and an anvil rod extending from the anvil head;

providing a suture structure including a cylindrical wall defining a lumen therethrough and a wound treatment material contained within the lumen of the suture structure;

inserting the anvil assembly into a first tissue section;

suturing the first tissue section about the anvil rod of the anvil assembly with the suture structure such that at least a portion of the suture structure extends at least partially across a tissue contacting surface of the anvil assembly;

inserting the distal end of the surgical stapling apparatus into a second tissue section;

connecting the anvil rod of the anvil assembly to the distal end of the surgical stapling apparatus; and

approximating the anvil head towards the distal end of the surgical stapling apparatus to capture the first and second tissue sections therebetween and to create pressure between the anvil head and the distal end of the surgical stapling apparatus and onto the suture structure, to rupture the suture structure thereby releasing the wound treatment material from the suture structure disposed between the first and second tissue sections.

7. The method of claim 6 , further comprising firing surgical staples from a staple cartridge assembly associated with the distal end of the surgical stapling apparatus to mechanically secure the first and second tissue sections.

8. A method of performing a surgical anastomosis procedure comprising:

providing a surgical stapling device including a body portion and a knife;

providing an anvil assembly including an anvil rod adapted to engage the body portion of the surgical stapling device;

providing a surgical suture including a wound treatment material disposed within a lumen of the surgical suture;

positioning the body portion adjacent a first tissue section;

positioning the anvil assembly adjacent a second tissue section;

disposing the surgical suture between the first and second tissue sections; and

approximating the anvil assembly and the body portion and actuating the knife of the surgical stapling device to cut the surgical suture thereby releasing the wound treatment material from the surgical suture.

9. The method of claim 8 , wherein the disposing of the surgical suture between the first and second tissue sections further includes securing the second tissue section about the anvil assembly with the surgical suture.

10. The method of claim 9 , wherein the securing of the second tissue section about the anvil assembly with the surgical suture further includes extending the surgical suture across a staple anvil pocket of the anvil assembly.

11. The method of claim 8 , further comprising:

connecting the anvil assembly and the body portion of the surgical stapling device to one another.

12. The method of claim 8 , further comprising:

firing the surgical stapling device, wherein the knife is actuated simultaneously with the firing of the surgical stapling device thereby releasing the wound treatment material from the surgical suture to mechanically and chemically secure the first and second tissue sections.

13. The method of claim 8 , wherein the actuating of the knife includes resecting portions of the first and second tissue sections.

14. The method of claim 13 , wherein the portions of the first and second tissue sections that are resected are located radially inward of the knife and whereby the actuating of the knife includes severing any portion of the surgical suture extending across the knife thereby expelling the wound treatment material from the surgical suture and onto the first and second tissue sections.

15. The method of claim 8 , wherein the wound treatment material is light activated, and wherein the method further includes irradiating the tissue sections with UV light to activate the wound treatment material.
