Patent ID: 8709026

Claim:
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.
