Abstract

According to an aspect of the present disclosure, a surgical suture needle assembly is provided including an elongate tube defining a lumen through at least a portion of a length thereof; and a wound treatment material contained within the lumen of the suture structure. The present disclosure further provides for methods of using the surgical suture needle assembly in anastomotic procedures and the like.

Claims

1. A method of performing an anastomotic procedure on adjacent tissue sections, the method comprising the steps of:

positioning a body portion of a surgical stapling device adjacent a first tissue section;

positioning an anvil assembly including an anvil rod adapted to engage the body portion of the surgical stapling device adjacent a second tissue section;

disposing a surgical suture between the first and second tissue sections, the surgical suture comprising;

a suture structure including a cylindrical wall defining a single, central lumen therethrough and at least one weakened portion formed in an outer surface of the wall thereof, the weakened portion extending in a line of reduced thickness longitudinally along at least a portion of the length of the wall; and

a wound treatment material contained within the lumen of the suture structure, the weakened portion being arranged to allow the suture structure to rupture upon application of a compressive force thereto; and

approximating the anvil assembly and the body portion by an amount sufficient to create a pressure on the surgical suture sufficient to rupture the suture structure and release the wound treatment material between the first and second tissue sections.

2. The method of claim 1, wherein the step of disposing a surgical suture between the first and second tissue sections further includes the step of securing the second tissue section about the anvil assembly with the surgical suture.

3. The method of claim 2, wherein the step of securing the second tissue section about the anvil assembly with the surgical suture further includes the step of extending the surgical suture across at least one staple anvil pocket of the anvil assembly.

4. The method of claim 1, further comprising the step of securing the first tissue section about the body portion of the surgical stapling device with a surgical suture.

5. The method of claim 4, further comprising the step of providing a surgical stapling device including a body portion having a staple cartridge assembly associated therewith, and wherein the step of securing the first tissue section about the body portion of the surgical stapling device further includes the step of extending the surgical suture across at least one staple pocket of the staple cartridge assembly.

6. The method of claim 1, further including the steps of:

connecting the anvil assembly and the body portion of the surgical stapling apparatus to one another; and

firing the surgical stapling apparatus to mechanically and chemically secure the first tissue section and the second tissue section.

7. The method of claim 6, further comprising the step of providing a surgical stapling device having a knife associated therewith, and wherein the step of firing the surgical stapling device includes the step of actuating the knife to resect portions of the first and second tissue sections and to cut the surgical suture thereby releasing wound treatment material therefrom.

8. The method of claim 7, wherein the portions of the first and second tissue sections to be resected are located radially inward of the knife thereby severing any portion of the surgical suture extending across the knife and thereby expelling wound treatment material from the surgical suture and onto the first and second tissue sections.

9. The method of claim 1, further comprising the step of providing a surgical suture having a wound treatment material that is light activated, and wherein the method further includes the step of irradiating the tissue sections with UV light to activate the wound treatment material.

10. A method of joining tissue, the method comprising the steps of:

advancing an anvil assembly including an anvil head and an anvil rod extending from the anvil head with respect to a body portion of an anastomosis instrument;

disposing a first tissue section around the anvil assembly and disposing a second tissue section around the body portion so that the first tissue section and the second tissue section are interposed between the anvil head and the anastomosis instrument;

disposing a surgical suture between the anvil head and the anastomosis instrument, the surgical suture including a monofilament suture structure defining a solid elongate core having a perimeter and a wound treatment material deposited around the perimeter and dispersed throughout the solid elongate core of the suture structure; and

approximating the anvil and the body portion thereby contacting the first and second tissue sections with the wound treatment material of the surgical suture.

11. The method of claim 10, further comprising the step of providing a pressure activated surgical suture, and wherein the step of approximating the anvil head and the anastomosis instrument further includes the step of creating a pressure between the anvil head and the anastomosis device that exceeds a threshold pressure level to active the wound treatment material.

12. The method of claim 10, further comprising the step of firing the anastomosis instrument to mechanically and chemically secure the first and second tissue sections.

13. The method of claim 10, further comprising the steps of:

disconnecting the anvil assembly from the anastomosis instrument; and

withdrawing the anvil assembly and the anastomosis instrument from the first and second tissue sections.

14. The method of claim 10, further comprising the step of:

disconnecting the anvil assembly from the body portion of the anastomosis instrument before disposing a first tissue section around the anvil assembly and disposing a second tissue section around the body portion.

15. The method of claim 14, further comprising the step of:

connecting the anvil assembly to the body portion of the anastomosis instrument before approximating the anvil assembly and body portion.

16. A method of joining tissue comprising the steps of:

disposing adjacent tissue sections between an anvil assembly and a cartridge assembly of a surgical stapling apparatus;

securing at least one of the anvil assembly and the cartridge assembly to a respective tissue section with a suture structure, the suture structure including a cylindrical wall defining a single central lumen including;

a wound treatment material contained within the lumen; and

at least one weakened portion formed in an outer surface of the wall thereof; and

approximating the anvil assembly and the cartridge assembly to create a pressure on the tissue sections and the suture structure interposed therebetween that is sufficient to rupture the suture structure at least along the weakened portion thereof to release the wound treatment material therefrom.

17. The method of claim 16, further comprising the step of ejecting staples from the cartridge assembly and forming the staples against the anvil assembly to mechanically secure the tissue sections to one another.
