  • Patent number: 6045560
    Abstract: A surgical stapling apparatus having tissue bolstering material releasably attached thereto for application of the material and staples to body tisuse is disclosed. The tissue bolstering material is preferably releasably held to surfaces of the stapling apparatus through pins, clips or similar securing structures. The tissue bolstering material can be either planar or tubular in configuration. Preferably, both the anvil portion and the fastener ejecting portion of the stapler are at least partially covered with the tissue bolstering material. In use, tissue is disposed between the anvil portion and the stapling portion of the instrument and the instrument is fired. The tissue bolstering material is thereby secured to the tissue and releasably detaches from the stapler upon withdrawal of the stapler from the surgical site.

  • Patent number: 5964774
    Abstract: A surgical stapling apparatus having tissue bolstering material disposed thereon for application of the material and staples to body tissue. Two tissue bolstering members are preferably provided, each member being generally planar in configuration, wherein a first member corresponds to the dimensions of the tissue contacting surface of a staple cartridge and a second member corresponds to the dimensions of the tissue contacting surface of an anvil. In use, tissue is disposed between the anvil and the staple cartridge and the instrument is fired, thereby securing the tissue bolstering material to the tissue.

  • Patent number: 5795584
    Abstract: Surgical adhesion barriers and methods of using such surgical adhesion barriers are provided. Surgical adhesion barriers according to the present invention have at least one layer of a bioabsorbable material comprising copolymers and/or block copolymers derived from trimethylene carbonate. Alternatively, a multilayer surgical structure having one or more bioabsorbable layers superimposed on a non-absorbable layer is useful for minimizing or preventing formation of fibrous adhesions between a healing trauma site and adjacent surrounding tissue. Alternatively, a bioabsorbable non-woven fabric in adherent contact with at least one bioabsorbable layer of foam, film, mesh, web or woven fabric is also provided. One or more medicinal agents may be interposed between or disposed within any of the aforementioned layers.

  • Patent number: 5542594
    Abstract: A surgical stapling apparatus having biocompatible surgical fabric releasably attached thereto for application of the fabric and staples to body tisuse is disclosed. The fabric is releasably held to surfaces of the stapling apparatus through pins, clips or similar securing structures. The biocompatible surgical fabric can be either planar or tubular in configuration. Preferably, both the anvil portion and the fastener ejecting portion of the stapler are at least partially covered with the biocompatible surgical fabric. In use, tissue is disposed between the anvil portion and the stapling portion of the instrument and the instrument is fired. The biocompatible surgical fabric is thereby secured to the tissue and releasably detaches from the stapler upon withdrawal of the stapler from the surgical site.
