Abstract
Surgical methods involving cutting and sealing tissue include affixing a first adjunct material to tissue at a treatment site, such as by stapling the adjunct to tissue. A second adjunct material is applied to at least a portion of the first adjunct material such that the second adjunct material interacts with the first adjunct material to form a seal in an area of the tissue covered by at least one of the first and the second adjunct material. The resulting tissue sealing structure, which includes a combination of the two adjuncts, is believed to be superior to the sealing properties of either adjunct alone.

A method for forming an adjunct, comprising:
- weaving first fibers together to form a first layer;
- and
- interlocking or knotting second fibers with the first woven fibers to form a second layer that is connected to the first layer,
- wherein the adjunct is configured to be elastically deformable, to be releasably retained on a stapling body, and to allow a plurality of staples disposed within the stapling body to pass therethrough such that the adjunct can be attached to tissue by the plurality of staples.
