  • Patent number: 10610226
    Abstract: Adjunct material and methods of using adjunct material to reinforce a staple line are provided herein. In general, adjunct material can be used to maintain a seal in 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 be sized and shaped so that a portion of the material extends laterally outside of the staple line and distributes strain to tissue outside of the staple line. In certain aspects, sealant can be applied to the staple line and to the adjunct material in various ways to further seal the tissue and/or prevent leaks from forming in the tissue.

  • Patent number: 8551941
    Abstract: The present invention includes both sterilized and unsterilized hemostatic compositions that contain a continuous, biocompatible liquid phase having a solid phase of particles of a biocompatible polymer suitable for use in hemostasis and which is substantially insoluble in the liquid phase, and a discontinuous, biocompatible gaseous phase, each of which is substantially homogenously dispersed throughout the continuous liquid phase, methods for making such compositions, medical devices that contain sterilized hemostatic compositions disposed therein and methods of making such devices.

  • Patent number: 7279177
    Abstract: The present invention is directed to a hemostatic wound dressing that utilizes a fibrous, fabric substrate made from carboxylic-oxidized cellulose and containing a first surface and a second surface opposing the first surface, the fabric having flexibility, strength and porosity effective for use as a hemostat; and further having a porous, polymeric matrix substantially homogeneously distributed on the first and second surfaces and through the fabric, the porous, polymeric matrix being made of a biocompatible, water-soluble or water-swellable cellulose polymer, wherein prior to distribution of the polymeric matrix on and through the fabric, the fabric contains about 3 percent by weight or more of water-soluble oligosaccharides.
