  • Patent number: 6436425
    Abstract: Non-gelling polyoxyalkylene compositions, and methods of their use for inhibiting surgical adhesion formation/reformation in mammals are disclosed. The useful non-gelling compositions preferably comprise polyoxyalkylene block copolymer at desired concentrations with or without a therapeutic agent. When used with an incorporated drug, the non-gelling compositions serve as a carrier providing sustained or prolonged release of the therapeutic agent.

  • Patent number: 6346272
    Abstract: Balanced pH, thermo-irreversible gels are ideal vehicles for drug delivery to a body cavity of a mammal. The gels contain a mixture of a polyoxyalkylene block copolymer or polyether together with an ionic polysaccharide which is thermo-irreversibly gelled in the presence of a counter-ion.

  • Patent number: 6136334
    Abstract: Balanced pH, hyperosmotic, hypoosmotic, or isoosmotic gels are ideal vehicles for drug delivery. They are especially suited for topical body cavity or injection application of drugs or diagnostic agents; for drug or diagnostic agent delivery to the eye of a mammal; as protective corneal shields; or as ablatable corneal masks useful in laser reprofiling of the cornea. The compositions without the addition of a drug or diagnostic agent are useful as medical devices, for instance, in separating surgically or otherwise injured tissue as a means of preventing adhesions.

  • Patent number: 5800711
    Abstract: A process for the fractionation of polyoxyalkylene block copolymers wherein the polydispersity of the polyether is reduced. The fractionation process, which removes lower molecular weight species such as polyoxyalkylene homopolymer, truncated polyoxyalkylene diblock polymers, or other reaction byproducts, comprises salt extraction and liquid phase separation to provide a product with a narrower molecular weight distribution, lower degree of unsaturation, and distinctly different physical characteristics compared to the starting material.

  • Patent number: 5681576
    Abstract: A process and compositions for reducing post-surgical adhesion formation/reformation in mammals following injury to organs situated in mammalian body spaces. Aqueous, isotonic gel compositions, preferably at mammalian body fluid pH, comprising a polyoxyalkylene polymer are applied to injured areas of the organs situated in body cavities such as, the peritoneal, pelvic, or pleural cavity.
