  • Patent number: 9353218
    Abstract: Multifunctional compounds are provided that readily crosslink in situ to provide crosslinked biomaterials. The multifunctional compounds contain a single component having at least three reactive functional groups thereon, with the functional groups selected so as to be non-reactive in an initial environment and inter-reactive in a modified environment. Reaction of a plurality of the multifunctional compounds results in a three-dimensional crosslinked matrix. In one embodiment, a first functional group is nucleophilic, a second functional group is electrophilic, and at least one additional functional group is nucleophilic or electrophilic. Methods for preparing and using the multifunctional compounds, and kits including the multifunctional compounds are also provided. Exemplary uses for the multifunctional compounds include tissue augmentation, biologically active agent delivery, bioadhesion, and prevention of adhesions following surgery or injury.

  • Publication number: 20140017200
    Abstract: Compositions, methods of manufacture and methods of treatment for post-myocardial infarction are herein disclosed. In some embodiments, the composition includes at least two components. In one embodiment, a first component can include a first functionalized polymer and a substance having at least one cell adhesion site combined in a first buffer at a pH of approximately 6.5. A second component can include a second buffer in a pH of between about 7.5 and 9.0. A second functionalized polymer can be included in the first or second component. In some embodiments, the composition can include at least one cell type and/or at least one growth factor. In some embodiments, the composition(s) of the present invention can be delivered by a dual bore injection device to a treatment area, such as a post-myocardial infarct region.

  • Patent number: 8617584
    Abstract: The present invention relates generally to synthetic polymer compositions that form interpenetrating polymer networks. In a preferred embodiment, the compositions comprise two multifunctionally activated synthetic polymers, along with a tensile strength enhancer. Such compositions form matrices that exhibit superior cohesive strength and in many instances can serve as adequate replacements for surgical means of attaching tissues, such as sutures, sponges and medical staples.
