  • Patent number: 8221735
    Abstract: Embolic compositions comprising macromers having a backbone comprising a polymeric backbone comprising units with a 1,2-diol or 1,3-diol structure, such as polyvinyl alcohol, and pendant chains bearing crosslinkable groups and, optionally, other modifiers. When crosslinked, the macromers form hydrogels having many properties advantageous for use as embolic agents to block and fill lumens and spaces. The embolic compositions can be used as liquid embolic agents and crosslinked in situ or as preformed embolic articles, such as microspheres.

  • Patent number: 7803872
    Abstract: A water-soluble, halogen-resistant film-forming composition useful for packaging water treatment products is disclosed. The film can include an acid-stable, water-soluble polyvinyl alcohol polymer, an oxidizable organic material, a chelating agent, a free radical scavenger, and secondary additives such as plasticizers, lubricants, and surfactants. The resulting film has favorable solubility properties after having been exposed to halogenated (e.g., chlorinated and brominated) compositions such as water treatment and agricultural products for prolonged periods of time.

  • Patent number: 7008635
    Abstract: Hydrogels intended for orthopedic applications, including repair and regeneration of cartilage, bone, joint surfaces and related tissues, must possess greater strength and toughness than hydrogels used in soft tissue repair. A hydrogel formulation is provided which has high strength, toughness, a suitable mechanical modulus and low equilibrium hydration. It may also have controlled porosity or degradation time. It can be made to polymerize in situ with high (“good” to “excellent”) adherence to target tissue or surfaces. A preferred formulation for forming such gels comprises 40 to 80% by weight of a low-molecular weight polar monomer and 30 to 10% of a hydrophilic macromeric crosslinker.

  • Patent number: 6652883
    Abstract: Compositions comprising macromers having a backbone comprising units having a 1,2-diol and/or 1,3-diol structure for tissue bulking and coating. Such polymers include poly(vinyl alcohol) (PVA) and hydrolyzed copolymers of vinyl acetate, for example, copolymers with vinyl chloride, N-vinylpyrrolidone, etc. The backbone polymer contains pendant chains bearing crosslinkable groups and, optionally, other modifiers. When crosslinked, the macromers form hydrogels having many properties advantageous for use as agents to bulk and coat tissues.

  • Patent number: 6387977
    Abstract: An impoved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitiator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as “priming”. The polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, “priming” can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other.

  • Patent number: 6177095
    Abstract: Water-soluble macromers including at least one hydrolysable linkage formed from carbonate or dioxanone groups, at least one water-soluble polymeric block, and at least one polymerizable group, and methods of preparation and use thereof are described. The macromers are preferably polymerized using free radical initiators under the influence of long wavelength ultraviolet light or visible light excitation. Biodegradation occurs at the linkages within the extension oligomers and results in fragments which are non-toxic and easily removed from the body. The macromers can be used to encapsulate cells, deliver prophylactic, therapeutic or diagnostic agents in a controlled manner, plug leaks in tissue, prevent adhesion formation after surgical procedures, temporarily protect or separate tissue surfaces, and adhere or seal tissues together.
