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.
Claims7
A method of joining tissue, the method comprising:
- 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, and across a staple cartridge assembly of the anastomosis instrument, the surgical suture including an elongate core having a perimeter and a wound treatment material at least one of deposited around the perimeter and dispersed within the elongate core of the surgical suture, the wound treatment material configured to be activated when subjected to a predetermined threshold pressure;
- and
- approximating the anvil head and the body portion to create pressure between the anvil head and the anastomosis instrument that exceeds the threshold pressure to activate the wound treatment material between the first and second tissue sections.

A method of performing a surgical anastomosis procedure comprising:
- inserting an anvil assembly into a first tissue section, the anvil assembly including an anvil head and an anvil rod extending from the anvil head;
- suturing the first tissue section about the anvil rod of the anvil assembly with a suture structure such that at least a portion of the suture structure extends transversely over a tissue contacting surface of the anvil assembly, the suture structure including an elongate core and a wound treatment material incorporated into the elongate core;
- inserting a distal end of a 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 that exceeds a threshold pressure to activate the wound treatment material between the first and second tissue sections.
