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.

Abstract: Bronchus sealants and methods of sealing bronchial tubes are provided. In general, the bronchus sealants and methods of sealing bronchial tubes can facilitate sealing of stapled bronchial tubes. In some embodiments, a reinforcement material can be introduced into a bronchial tube, and then the bronchial tube and the reinforcement material can be stapled using a surgical stapler. A sealant can be introduced into the bronchial tube and can harden therein, thereby helping to seal the bronchial tube where the bronchial tube was stapled. The sealant can be introduced into the bronchial tube before and/or after the stapling of the bronchial tube and the reinforcement material.

Abstract: A method is described for the measurement of thrombin activity in the presence of fibrinogen, or for the measurement of the functionality of fibrinogen in the presence of thrombin.

Abstract: The present invention relates to a sealant formulation comprising a blend containing fibrinogen and an exogenous activator of a member of a mammalian blood clotting cascade.

Abstract: The present invention includes sterilized 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 that is substantially insoluble in the liquid phase, and sterile thrombin, each of which is substantially homogenously dispersed throughout the continuous liquid phase, and methods for making such compositions.

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.

Abstract: The present invention is directed to processes of making flowable hemostatic compositions and devices that include the flowable hemostatic composition disposed therein, where a volume of a biocompatible liquid, a volume of a biocompatible gas, and an amount of solid particles of a biocompatible polymer are mixed together to form a substantially homogenous composition including a discontinuous gas phase and the solid particles substantially homogenously dispersed throughout a continuous liquid phase to form a flowable hemostatic composition, and the composition then transferred into a device suitable for applying the flowable hemostatic composition to a site of a body requiring hemostasis under conditions effective to maintain the substantially homogeneous dispersion of the gas phase and the solid particles throughout the liquid phase.

Abstract: The present invention is directed to hemostatic devices comprising a substrate, which substrate comprises a precipitate of a protein in an amount effective to provide hemostatic properties to the substrate, or to maintain and/or improve hemostatic properties of the substrate, and to methods of making such devices, wherein the substrate comprising the precipitate of the protein is prepared by precipitation of the protein on or into the substrate upon contacting the protein with the substrate.

Abstract: The present invention includes both sterilized and unsterilized hemostatic compositions that contain a biocompatible liquid having particles of a biocompatible polymer suitable for use in hemostasis and which is substantially insoluble in the liquid, up to about 20 percent by weight of glycerol and about 1 percent by weight of benzalkonium chloride, each based on the weight of the liquid, all of which are substantially homogenously dispersed throughout the liquid to form a substantially homogenous composition, methods for making such compositions, medical devices that contain such hemostatic compositions disposed therein and methods of making such devices.
