  • Publication number: 20090192214
    Abstract: Compositions are disclosed that afford drug delivery from two-part polymer compositions that rapidly form covalent linkages when mixed together. Such compositions are particularly well suited for use in a variety of tissue related applications when rapid adhesion to the tissue and gel formation is desired along with drug delivery. For example, the compositions are useful as tissue sealants, in promoting hemostasis, in effecting tissue adhesion, in providing tissue augmentation, and in the prevention of surgical adhesions.

  • Publication number: 20090017091
    Abstract: The present application provides sterile hyaluronic polymer compositions than are useful, e.g., as medical devices, biomedical adhesives, and sealants. Generally, provided are sterile dry compositions comprising a thiol-derivatized hyaluronic acid and one or more stabilizing excipients. Also provided are related kits and methods. The compositions described herein are particularly robust to sterilizing irradiation, and substantially maintain both their molecular weight and gelation parameters such as gelation time after sterilization, such that such sterile compositions are capable of hydrogel formation.

  • Publication number: 20080312315
    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: 20040219214
    Abstract: A composition comprising a synthetic polymer, optionally in the presence of a drug, where the polymer comprises multiple activated groups. The multiple activated groups are reactive with functionality present on animal tissue, so that upon administration of the polymer to the tissue, the polymer binds to the tissue. Alternatively, the multiple activated groups are reactive with functionality present on a non-living surface, where the polymer binds to this surface to, e.g., increase the lubricity of the surface. When drug is present in the composition, the drug is then delivered to the site of polymer attachment.

  • Publication number: 20040197408
    Abstract: Formulations are formed of a diblock copolymer (X—Y) having a hydrophilic block X comprising residues of monomer x, and a hydrophobic block Y comprising residues of monomer y; an additive selected from an amino acid and an oligopeptide. Upon admixture with water, the formulations form drug delivery vehicles, preferably in micellar form. The inclusion of amino acid and/or oligopeptide provides for the formation of micelles at an enhanced rate, and/or provides the formation of micelles having an enhanced ability to incorporate drug(s), and/or provides the formation of micelles having advantageous physical characteristics.
