  • Patent number: 10625032
    Abstract: The present inventions are directed to spray tips for multidirectional or three-dimensional spraying of an unmixed two-part sealant and/or hemostat comprising a first biocompatible component and a biocompatible second component onto a tissue or wound comprising: a hollow body having inside a first component distribution compartment and a second component distribution compartment, said compartments not in fluid communication with each other. The first component can contain one or more biologic components, preferably fibrinogen and the second component can contain one or more biologic component different from the first biologic component, preferably thrombin and/or thrombin precursors. The present inventions are also directed to methods of spraying the unmixed two-part sealant or hemostat using the spray tip and associated components described above by simultaneously expressing the first component and the second component from the syringes.

  • Patent number: 10603408
    Abstract: A biocompatible tissue repair implant or scaffold device is provided for use in repairing a variety of tissue injuries, particularly injuries to cartilage, ligaments, tendons, and nerves. The repair procedures may be conducted with implants that contain a biological component that assists in healing or tissue repair. The biocompatible tissue repair implants include a biocompatible scaffold and particles of living tissue, such that the tissue and the scaffold become associated. The particles of living tissue contain one or more viable cells that can migrate from the tissue and populate the scaffold.

  • Patent number: 10258337
    Abstract: An apparatus includes a body assembly, a shaft, an end effector, and a cartridge. The end effector includes a jaw, a pivotable anvil, and a knife member. The cartridge includes a deck, a buttress assembly, and a folding sled. A first portion of the buttress assembly is positioned on top of the deck. A second portion of the buttress assembly is positioned within the longitudinal channel. The folding sled is configured to translate within the longitudinal channel to move the second portion of the buttress assembly to a position that is above the deck in response to actuation of the knife member. The second portion of the buttress assembly is thereby secured against edges of tissue severed by the knife member.
