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.

Claims

1. A surgical method, comprising:

affixing a first adjunct material onto a tissue at a treatment site;

applying a second adjunct material 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.

2. The method of claim 1, wherein the step of affixing is effected by stapling the first adjunct material to the tissue.

3. The method of claim 1, wherein at least one of the first and second adjunct materials is formed of oxidized regenerated cellulose.

4. The method of claim 1, wherein at least one of the first and second adjunct materials is formed from biocompatible, absorbable suture material, selected from the group consisting of polydioxanon, Polyglycerol sebacate, Polyglycolic acid, Polycaprolactone, Polylactic acid, Polyhydroxyalkanoate, Poliglecaprone 25, polyglactin 910, polyglyconate, polyglocolide-trimethylene carbonate, polyhydroxybutyrate, poly(vinylpyrrolidone), poly(vinyl alcohol), absorbable polyurethanes, and regenerated cellulose.

5. The method of claim 1, wherein at least one of the first and second adjuncts is made of multiple layers.

6. The method of claim 1, wherein at least one of the adjunct materials includes a therapeutic agent.

7. The method of claim 1, wherein at least one of the adjunct materials is made of a bioabsorbable material or a biofragmentable material.
