  • Patent number: 6913805
    Abstract: The present invention provides an apparatus and method for controlled release of a fumigant into a wooden structure to prevent decay of that structure. According to the present invention, a fumigant in an ampule or container is inserted into the wooden structure. The ampule or container is made of a polymeric material that does not react with the fumigant, but having walls which are permeable to the fumigant such that, when inserted into the wooden structure, the rate of release of the fumigant through the walls of the ampule is slow enough to continuously treat and arrest decay of the wooden structure, particularly decay caused by fungi, over extended periods of time (i.e., 1, 5, 7, 10, 15, 20 or 30 years). The rate of release of the fumigant can be controlled by the type of fumigant, the shape of the container, the specific polymer used to make the container, and by the thickness of the container wall.

  • Patent number: 6884778
    Abstract: A new oligomer based on alternating fumaric acid and poly(ethylene glycol) (PEG) units is provided. The oligo(PEG fumarate) (OPF) may be functionalized by modification with a biocompatible organic group. Further, the OPF may be cross-linked using radical polymerization in the presence of either a chemical or photo initiator. A cross-linked OPF gel has a swelling behavior that is tunable dependent on the molecular weight of PEG. A cross-linkable PEG macromer, as exemplified by oligo(PEG fumarate), has unsaturated double bonds, for example in the fumaryl groups, along its macromolecular chain that allows for the preparation of hydrogels with tailored structure and properties.

  • Patent number: 6864350
    Abstract: PEG and related polymer derivatives having weak, hydrolytically unstable linkages near the reactive end of the polymer are provided for conjugation to drugs, including proteins, enzymes, small molecules, and others. These derivatives provide a sufficient circulation period for a drug-PEG conjugate and then for hydrolytic breakdown of the conjugate and release of the bound molecule. In some cases, drugs that previously had reduced activity when permanently coupled to PEG can have therapeutically suitable activity when coupled to a degradable PEG in accordance with the invention. The PEG of the invention can be used to impart water solubility, size, slow rate of kidney clearance, and reduced immunogenicity to the conjugate. Controlled hydrolytic release of the bound molecule in the aqueous environment can then enhance the drug delivery system.

  • Patent number: 6861065
    Abstract: Methods of producing an intraocular lens in vivo comprise preparing a composition of discrete water soluble macromolecular particles, mixing the composition with a water soluble photoinitiator and forming an opthalmically acceptable aqueous solution having a refractive index of at least 1.39, injecting the resulting aqueous solution into the capsular bag of an eye, and initiating crosslinking between the macromolecular particles by irradiation of a wavelength in the range of about 380 to 700 nm to create a lens in the capsular bag.

  • Publication number: 20040265475
    Abstract: Methods for coating different regions of an implantable device are disclosed. An embodiment of the method includes dipping a first portion of the implantable device into a first coating substance, and then centrifuging the implantable device to provide an even coating. Next, a second portion of the implantable device is dipped into a second coating substance, and the implantable device is again centrifuged, resulting in an even second coating. In another embodiment, a first coating substance is applied to an interior surface of a cylindrical implantable device, such as a stent or graft, and a second coating substance is applied to an exterior surface. A centrifuge step is performed so that the first coating substance is preferentially and uniformly applied on the interior surface of the implantable device and the second coating substance is preferentially and uniformly applied on the exterior surface of the implantable device.
