摘要:
Intravascular devices (e.g., stents, stent grafts, covered stents, aneurysm coils, embolic agents and drug delivery catheters and balloons) are used in combination with fibrosing agents in order to induce fibrosis that may otherwise not occur when the implant is placed within an animal or to promote fibrosis betweent the devices and the host tissues. Compositions and methods are described for use in the treatment of aneurysms and unstable arterial (vulnerable) plaque.
摘要:
Herein are provided derivatized hyperbranched polyglycerols (“dHPGs”). The dHPG comprises a core comprising a hyperbranched polyglycerol derivatized with C1C20 alkyl chains and a shell comprising at least one hydrophilic substituent bound to hydroxyl groups of the core, wherein the hyperbranched polyglycerol comprises from about 1 to about 200 moles of the at least one hydrophilic substituent. The dHPGs are for use as agents for the delivery of a drug or other biologically active moiety to the urinary tract, the digestive tract, the airways, the vaginal cavity and cervix and the peritoneal cavity to treat indications such as cancer, which may be useful in the treatment of or the manufacture of a medicament, in the preparation, of a pharmaceutical composition for the treatment of cancer, as a pre-treatment or co-treatment to improve drug uptake in a tissue. Furthermore, there are provided methods of making dHPGs.

The present invention describes compositions, devices, and methods for the production, use and administration of the composition having a non-thermoreversible block copolymer composition.
摘要:
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.
摘要:
Agents, compositions, and implants are provided herein for treating diverticular disease (e.g., diverticulosis and diverticulitis). In particular, fibrosis-inducing agents, hemostatic agents, and/or anti-infective agents, or compositions containing one or more of these agents are provided for use in methods for treating diverticular disease.

摘要:
Compositions comprising anti-fibrotic agent(s) and/or polymeric compositions can be used in various medical applications including the prevention of surgical adhesions, treatment of inflammatory arthritis, treatment of scars and keloids, the treatment of vascular disease, and the prevention of cartilage loss.
摘要:
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.
