  • Publication number: 20040225077
    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: 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: 20040199241
    Abstract: Silk-containing stent grafts are provided comprising an endoluminal stent and a graft, wherein the silk is induces the in vivo adhesion of the stent graft to vessel walls, or, otherwise induces or accelerates an in vivo fibrotic reaction causing said stent graft to adhere to vessel wall. Also provided are methods for making and using such stent grafts.

  • Publication number: 20040146546
    Abstract: The present invention provides compositions, devices, and methods for maintaining or improving the integrity of body passageways following surgery, such as at a graft site, or injury. Delivery devices including one or more therapeutic agents and a mesh are described. Representative examples of therapeutic agents include microtubule stabilizing agents, anti-angiogenic factors, inhibitors of smooth muscle cell growth or proliferation, non-steroidal anti-inflammaory drugs, and other factors useful preventing and/or reducing a proliferative biological response that may obstruct or hinder the optimal functioning of the passageway or cavity.
