  • Patent number: 8889174
    Abstract: A coaxial implant has been developed using biodegradable polymeric materials. The coaxial implant has a core containing drug, surrounded by a semi-permeable membrane that controls the rate of release of material from the core. The core containing the drug and the polymer membrane(s) can be the same or different polymer. The core acts as a reservoir of drug, which partitions from the core polymer to form a saturated solution of drug at the polymer membrane.

  • Publication number: 20140193365
    Abstract: The present disclosure provides a biodegradable drug delivery composition including a vehicle and an insoluble component comprising beneficial agent dispersed in the vehicle. Typically, the composition is not an emulsion, but has a low viscosity and further provides for minimized initial burst and sustained release of the beneficial agent over time. Also provided, are kits including the biodegradable drug delivery composition or components thereof, as well as methods of making and using the biodegradable drug delivery composition.

  • Patent number: 8722078
    Abstract: Polymeric devices for controlled release of an active agent of interest are provided. The active agent is provided within a biodegradable polymer system to supply a polymeric device for controlled release of the active agent. The polymer system is a copolymer or a polymer blend comprising a hydrophobic component and a hydrophilic component, and the polymer system does not form a hydrogel when contacted with, or immersed in an aqueous system, for example when the device is implanted in a subject. When the device is administered to a subject, for example, when it is implanted, the device releases the active agent in a controlled fashion without a lag period, or with a minimal lag period. Methods for producing the polymeric devices are also provided, as are methods of using the polymeric devices to provide for controlled release of an active agent in a subject.

  • Patent number: 8263108
    Abstract: A coaxial implant has been developed using entirely biodegradable polymeric materials. As referred to herein, a coaxial implant is a device having a core containing drug, surrounded by a semi-permeable membrane that controls the rate of release of material from the core. The device is formed by extrusion, using a pre-milling and extruding step to maximize uniformity of drug dispersion within the polymeric material. In one embodiment, the polymer is processed to yield a semi-crystalline polymer, rather than an amorphous polymer. The core containing the drug and the polymer membrane(s) can be the same or different polymer. The polymer can be the same or different composition (i.e., both polycaprolactone, or both poly(lactide-co-glycolide) of different monomer ratios, or polycaprolactone outside of a core of poly(lactide)), of the same or different molecular weights, and of the same or different chemical structure (i.e., crystalline, semi-crystalline or amorphous).

  • Patent number: 7833543
    Abstract: The present invention relates to novel nonpolymeric compounds and compositions that form liquid, high viscosity materials suitable for the delivery of biologically active substances in a controlled fashion, and for use as medical or surgical devices. The materials can optionally be diluted with a solvent to form a material of lower viscosity, rendering the material easy to administer. This solvent may be water insoluble or water soluble, where the water soluble solvent rapidly diffuses or migrates away from the material in vivo, leaving a higher viscosity liquid material.
