  • Patent number: 6586011
    Abstract: A drug delivery system which includes a plurality of microcapsules, each microcapsule containing a plasminogen activator entrapped in a biocompatible, biodegradable, substantially water-soluble polymeric matrix such that the plasminogen activator is releasable therefrom upon exposure of the microcapsules to an aqueous environment, as well as methods for preparing same. Methods of treating a thrombotic condition and reducing the time required for reperfusion of an occluded blood vessel are also described, which include parenterally administering to a mammal a therapeutically effective amount of a pharmaceutical composition which includes a plurality of such microcapsules.

  • Patent number: 5503850
    Abstract: A composition comprising a plurality of microcapsules suitable for parenteral injection into a mammal comprising a plasminogen activator-containing core, and a semi-permeable biocompatible layer surrounding the core permitting controlled release of at least a portion of the plasminogen activator. A method of reducing the time required for reperfusion of an artery containing a thrombus and a method to reduce the standard dosage requirement of a plasminogen activator in a mammal comprising intravenous injection of a composition comprising a plurality of microcapsules comprising a plasminogen activator core surrounded by a controlled release semi-permeable layer.

  • Patent number: 5106691
    Abstract: A method for producing polymeric films in which a substrate surface is contacted with a surfactant solution, comprising a liquid in which at least a first surfactant is dissolved, so that an interface is formed between the substrate surface and the surfactant solution, under conditions which promote the assembly at such interface of surfactant molecules, such assembled molecules defining a surfactant template for the film to be produced. After monomer molecules have become concentrated within the surfactant template, polymerization is effected to produce an ultrathin polymeric film dimensionally determined by the surfactant template. Such film is characterized by a polymer network disposed within a surfactant template. The method of the present invention may be used to coat the surface of an object, such as an object which is porous or has non-planar surfaces, or may be used to coat particulate matter.
