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.
Claims11
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.

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.
