Abstract

Adjunct material and methods of using adjunct material to reinforce tissue in proximity to a staple line are provided herein. In general, the adjunct material can be used to maintain a seal in tissue, such as lung tissue, and prevent stapled tissue from tearing. This adjunct material can be coupled to a jaw of a surgical stapler, and can be deployed into tissue along with the staples. In some embodiments, the adjunct material can comprise an outer material encompassing an inner, hydrophilic swellable material. The outer material can be selectively dissolvable and / or absorbable. When the outer material is punctured by staples or otherwise penetrated, moisture is passed to the inner material which then swells and expands to transition to a predetermined shape to seal the tissue and prevent leaks from forming in the tissue. Portions of the inner material around the staple line can transition to a large radius.

Description

technical field [0001] The subject matter disclosed herein relates to methods and apparatus for reinforcing staple lines. Background technique [0002] Surgical staplers are used in surgical procedures to seal, separate and / or transect tissue in the body by closing openings in tissue, blood vessels, catheters, shunts, or other objects or body parts involved in a particular procedure. The opening may be naturally occurring, such as a passage in a blood vessel, airway, or lumen or organ such as the stomach, or the opening may be passed by a surgeon during a surgical procedure, such as puncturing tissue or blood vessels to create a bypass or anastomosis, or Formed by cutting tissue during suture surgery. [0003] Most staplers have a handle comprising an elongated flexible or rigid shaft having a pair of opposing pairs formed on its ends for retaining and forming staples therebetween Jaws. At least one of the opposing jaws is movable relative to the other jaw. In the case o...
