  • Publication number: 20080146652
    Abstract: Anhydrous 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 a polymer and an organic solvent, where the solvent is water-miscible and biocompatible, and the polymer is hydrophobic or hydrophilic and comprises residues of monomers x and/or y, the polymer optionally having a molecular weight that is less than the molecular weight of the diblock copolymer; and a drug. Upon admixture with water, the anhydrous formulations form drug delivery vehicles, preferably in micellar form. The inclusion of polymer and/or organic solvent 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, e.g., advantageous viscosity and/or melting point.

  • Publication number: 20080085855
    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-inflammatory 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.
