  • Patent number: 11154570
    Abstract: The present invention generally relates to iron-polysaccharide (polydextrose) complexes and methods for the preparation thereof. In particular, the present invention relates to iron-polydextrose complexes and methods for the preparation thereof. The inventive complexes are suitable for use in various compositions, including particulate compositions that may be incorporated in various forms of administration, including tablets, capsules, and intravenous formulations. The complexes and compositions of the present invention are suitable for use in the treatment of iron deficient anemia. Advantageously, in addition to providing iron supplementation the complexes and compositions of the present invention provide certain advantages based on the presence of polydextrose (e.g., its low glycemic index and high fiber content).

  • Patent number: 9296011
    Abstract: An interventional device for delivery of beneficial agent to a lumen and methods of loading and manufacture of the same, which include a prosthesis loaded with beneficial agent to provide a controlled dosage concentration of beneficial agent to the lumen. The beneficial agent is loaded onto the prosthesis by a fluid-dispenser having a dispensing element capable of dispensing the beneficial agent in discrete droplets, each droplet having a controlled trajectory. The interventional device has a controlled local areal density of beneficial agent for systemic delivery or delivery to the luminal wall. The local areal density of beneficial agent may be varied along the prosthesis. The interventional device includes overlapping or bifurcated stents having a controlled areal density of beneficial agent.

  • Publication number: 20110262621
    Abstract: A beneficial agent can be loaded as discrete droplets on a prosthesis, such as a stent. Relative movement between the prosthesis and a dispensing element can be controlled to define a dispensing path in a raster format. The discrete droplets can be dispensed from a dispensing element when the dispensing element is detected to be in alignment with a cavity formed in the prosthesis such that the discrete droplets are deposited in the cavity. The discrete droplets can be dispensed from a dispensing element when the dispensing element is detected to be in alignment with a structural element of the prosthesis such that the discrete droplets are deposited on the structural element.

  • Publication number: 20080003254
    Abstract: A drug-eluting endoprosthesis is configured for inhibiting restenosis and thrombosis, and for promoting healing of a lesion in a body of a subject. Such an endoprosthesis includes at least a supporting structure and a therapeutically effective amount of the rapamycin analog is disposed thereon. The therapeutically effective amount of the rapamycin analog allows for the rapamycin analog to elute from the supporting structure so as to obtain a concentration of the rapamycin analog that is sufficient for inhibiting restenosis and/or inhibiting thrombosis. Also, the therapeutically effective amount of rapamycin analog is substantially devoid of inhibiting cell migration such that migrating cells promote healing of the lesion.

    Abstract: A drug-eluting endoprosthesis is configured for inhibiting restenosis and thrombosis, and for promoting healing of a lesion in a body of a subject. Such an endoprosthesis includes at least a supporting structure and a therapeutically effective amount of dexamethasone is disposed thereon. The therapeutically effective amount of dexamethasone allows for the drug to elute from the supporting structure so as to obtain a concentration of dexamethasone that is sufficient for inhibiting restenosis and/or inhibiting thrombosis. Also, the therapeutically effective amount of dexamethasone is substantially devoid of inhibiting cell migration such that migrating cells promote healing of the lesion. Additionally, the therapeutically effective amount of dexamethasone induces cell migration such that migrating cells promote healing of the lesion.
