  • Publication number: 20170055981
    Abstract: A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.

  • Publication number: 20060222680
    Abstract: The present invention is drawn to methods of preparing crosslinked collagen microspheres and microparticles, where a solution of soluble collagen in an aqueous acidic medium is combined with an emulsifying agent to form a first mixture of the soluble collagen solution and the emulsifying agent, the first mixture then is combined with a hydrophobic liquid under conditions effective to form water-in-oil emulsion of the hydrophobic liquid and the first mixture, the water-in-oil emulsion then is added to a buffered alcohol solution under conditions effective to form a dispersion of a continuous liquid phase and a dispersed solid phase of collagen fibers reconstituted from the soluble collagen solution, the liquid phase then is removed from the dispersion to provide collagen microspheres, the collagen microspheres then are crosslinked to form crosslinked collagen microspheres, and the crosslinked collagen microspheres then are optionally dried to form crosslinked collagen microparticles.
