    摘要: 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.

    摘要: Methods for preventing and/or eliminating fogging of endoscope lenses during an endoscopic procedure which include the steps of introducing an endoscope into a body cavity and contacting the endoscope lens with a biocompatible and biodegradable composition containing a polyalkylene oxide while the lens is positioned within the body. Alternatively, the endoscope may be coated with a biocompatible polyHEMA coating which is activated by a biocompatible solution, such as water or saline, which may be introduced during use through a fluid conduit on the endoscope. Devices for preventing and/or eliminating fogging of endoscope lenses during endoscopic procedures and conveying antifogging solutions to the distal end of the endoscope are also provided, and may include a distensible applicator.

    摘要: A completely bioabsorbable reinforced composite material for use in medical implants and a method for making same. The composite material comprises a hybrid yarn of intimately co-mingled reinforcement fibers of a crystalline polymer and matrix fibers of a polymer having a glass transition temperature below the melting point of the crystalline polymer. The hybrid yarn is heated under pressure to a processing temperature between the glass transition temperature of the matrix fibers and the melting point of the crystalline polymer to form a continuous matrix with reinforcing fibers of crystalline polymer. The composite material may be formed by a two step consolidation process.

    摘要: A method for forming a surgical clip and fixture for use therein includes molding a polymeric clip body, the clip body having hinged legs, the polymer of the clip body being substantially amorphous. The clip body can then be moved to a desired configuration while being subjected to a temperature above the glass transition temperature. The molded clip body is then heated to a temperature within the crystallization range for a period of time sufficient to impart at least 20% crystallinity thereto to impart a spring back property. Also disclosed herein is a fixture for forming a surgical clip in accordance with this method.
