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.
Claims12
A surgical method, comprising:
- stapling a first adjunct material and a second adjunct material to a tissue surface at a treatment site with a plurality of staples, the first and second adjunct materials having a first layer that forms a seal around plurality of staples extending therethrough, a second layer that prevents stretching of tissue adjacent thereto, and a third layer that relieves strain on tissue adjacent thereto, wherein only the first layer of the first adjunct material overlies only the first layer of the second adjunct material to form an overlapping region, and wherein the staples extend through the overlapping region and the first layer in the overlapping region forms a seal around staples extending therethrough.
