  • Patent number: 7858835
    Abstract: Methods for producing biocompatible compositions are provided. The biocompatible compositions include an isocyanate-functional polyurethane prepolymer in combination with a foam control agent. The foam control agent decreases the formation of bubbles and/or foam in the biocompatible composition, thereby enhancing the physical properties of the biocompatible composition. The presence of the foam control agent does not compromise the strength of the biocompatible composition. The compositions prepared by the methods of the present disclosure may be used as adhesives or sealants for medical/surgical uses.

  • Publication number: 20100111919
    Abstract: Biocompatible compositions are provided which may include at least one polysaccharide, at least one salt, and at least one reactive component. The at least one polysaccharide, at least one salt, and at least one reactive component may be in a single solution or multiple solutions and combined utilizing means within the purview of those skilled in the art. The compositions of the present disclosure experience delayed gelation, permitting their manipulation after application to tissue, which may be desirable for certain surgical and/or medical procedures, including cosmetic surgery.

  • Publication number: 20090324721
    Abstract: Biocompatible crosslinked polymers, and methods for their preparation and use, are disclosed in which the biocompatible crosslinked polymers are formed from water soluble precursors having electrophilic and nucleophilic functional groups capable of reacting and crosslinking in situ. Methods for making the resulting biocompatible crosslinked polymers biodegradable, or not, are provided, as are methods for controlling the rate of degradation. The crosslinking reactions may be carried out in situ on organs or tissues or outside the body. In embodiments, the biocompatible crosslinked polymers and/or their precursors may be utilized in a surgical procedure, such as a polypectomy.
