  • Patent number: 9687592
    Abstract: A method for manufacturing a nerve regeneration-inducing tube with excellent pressure resistance, shape recovery property, anti-kink property, film exfoliation resistance, resistance to invasion of outer tissues, and leakage resistance. The tubular body is formed by weaving together fibers made up of biodegradable polymer. The outer surface of the tubular body is coated multiple times with a collagen solution. The lumen of the tubular body is filled with collagen. Viscosity of the collagen solution that is first applied to the outer surface of the tubular body is between 2 to 800 cps. Viscosity of the collagen solution that is subsequently applied is higher than viscosity of the first applied collagen solution.

  • Publication number: 20150098992
    Abstract: Provided is a composite formulation comprising multi-unit spheroidal tablets (MUSTs) encapsulated in a hard capsule and a method for preparing same. The inventive hard capsule composite formulation can effectively charge the MUSTs in the limited space of the capsule, which allows charging a high dose of different pharmaceutically active ingredients in a capsule with a relatively small size, to thereby increase the productivity and render it readily administered to patients. Also, the capsule has a good dissolution rate because the pharmaceutically active ingredients contained in the capsule are separated from one another; therefore, the dissolution rates of the ingredients are less affected by one another. It may also be possible to maximize the therapeutic effects of the pharmaceutically active ingredients since the composite formulation has good stability.

In accordance with the present invention, the tem controlled release” encompasses all kinds of controlled release, including slow release, sustained and delayed release. Particularly, the present invention results in active ingredients, entrapped in or otherwise incorporated in or coupled to polymer carriers or polymeric devices, such as micelles, nanoparticles, microspheres and other types of polymer devices for controlled release; the active ingredients are covalently bonded to the polymer carriers or polymeric devices.

  • Publication number: 20140271795
    Abstract: The present invention is a bioactive, nanofibrous material construct which is manufactured using a unique electrospinning perfusion methodology. One embodiment provides a nanofibrous biocomposite material formed as a discrete textile fabric from a prepared liquid admixture of (i) a non-biodegradable durable synthetic polymer; (ii) a biologically active agent; and (iii) a liquid organic carrier. These biologically-active agents are chemical compounds which retain their recognized biological activity both before and after becoming non-permanently bound to the formed textile material; and will become subsequently released in-situ as discrete freely mobile agents from the fabric upon uptake of water from the ambient environment.

  • Patent number: 8821958
    Abstract: A method for electrostatic coating of medical devices such as stents and balloons is described. The method includes applying a composition to a polymeric component of a medical device which has little or no conductivity. The polymeric component could be a material from which the body or a strut of the stent is made or could be a polymeric coating pre-applied on the stent. The polymeric component could be the balloon wall. A charge can then be applied to the polymeric component or the polymeric component can be grounded. Charged particles of drugs, polymers, biobeneficial agents, or any combination of these can then be electrostatically deposited on the medical device or the coating on the medical device. One example of the composition is iodine, iodine, iodide, iodate, a complex or salt thereof which can also impart imaging capabilities to the medical device.
