  • Patent number: 10179190
    Abstract: Methods of treating tissue of a patient, e.g., tissue of an organ such that the bladder, are described. The methods may comprise inserting a medical device within the bladder; and injecting a composition to separate a first layer of tissue from a second layer of tissue. The composition may comprise at least one polysaccharide compound having a concentration ranging from approximately 0.05% to approximately 25% by weight, with respect to the total weight of the composition. The composition may at least partially separate the first layer of tissue from the second layer of tissue. At least one of the first layer of tissue or the second layer of tissue may be a detrusor muscle tissue.
    Type: Grant

  • Patent number: 8168213
    Abstract: According to an aspect of the present invention, a medical device is provided which comprises a metallic substrate and polymeric region disposed over and in contact with the metallic substrate. The polymeric region comprises (a) a block copolymer that comprises (i) a hard polymer block that comprises a high Tg monomer and (ii) a soft polymer block that comprises a low Tg monomer, (b) an adhesion promoting copolymer that comprises (i) a first monomer that covalently or non-covalently bonds with the metallic substrate and (ii) a second monomer that is compatible with the low Tg monomer and/or the high Tg monomer and (c) a therapeutic agent. The polymeric region may further comprise an optional polymer that is used to tailor the release rate of the therapeutic agent.
