  • Patent number: 8802125
    Abstract: The invention concerns a system for biocompatible drug release comprising: (i) a polymer matrix; (ii) an inorganic component located inside said matrix and characterized by a lamellar structure with a net positive or negative charge able to intercalate (iii) a pharmacologically active principle into said lamellar structure, by establishing an ionic type of bond with it and thereby obtaining an intercalation compound. The preparation process for the release system comprises the stages of: treating the lamellar solid in such a way as to give it a net positive or negative charge, then combining it with the chosen active principle, also in an ionic form, to obtain an intercalation compound which is then mixed with the polymer matrix. The release system can be employed in making medical devices, like sutures, membranes, osteosynthesis plaques, multilayered devices, gels and drug delivery systems.

  • Patent number: 8795710
    Abstract: A laminated, bioimplantable dural graft product is configured for use as both an onlay graft and a suturable graft. The dural graft product is sufficiently pliable so as to sufficiently conform to a curvature of a tissue surface to which it is applied, such as the curved surface of a meningeal membrane. The use of the graft product can have improved properties, including suture retention strength and fluid impermeability. To use the dural graft product as an implant to replace, reinforce or strengthen bodily tissue, or to act as an adhesion barrier, the dural graft is placed in contact with bodily tissue and conforms to the curvature of the bodily tissue. Sutures can be used to maintain the contact between the dural graft and the bodily tissue.

    Abstract: Methods are provided for making freeze dried hydrogel and structures therefrom that may be introduced into a patient's body for medical applications. Precursor components are combined to initiate crosslinking. The combined precursor components are placed in a chilled tray, and allowed to crosslink to a desired level of complete crosslinking before and/or after being placed onto the tray. The partially crosslinked hydrogel is frozen and freeze dried. After freeze drying, the hydrogel is conditioned to substantially complete crosslinking, and formed into one or more structures, e.g., plugs, hemostatic, or other medical devices. For example, the hydrogel may be cut, machined, rolled, folded, compressed, and/or cored into that may be loaded into delivery devices that may be introduced into a body to implant or otherwise deliver the structures into the body, e.g., to seal a puncture or other passage through tissue.

  • Publication number: 20140147487
    Abstract: A method for controlling generation of biologically desirable voids in a composition placed in proximity to bone or other tissue in a patient by selecting at least one water-soluble inorganic material having a desired particle size and solubility, and mixing the water-soluble inorganic material with at least one poorly-water-soluble or biodegradable matrix material. The matrix material, after it is mixed with the water-soluble inorganic material, is placed into the patient in proximity to tissue so that the water-soluble inorganic material dissolves at a predetermined rate to generate biologically desirable voids in the matrix material into which bone or other tissue can then grow.

  • Patent number: 8734829
    Abstract: An implantable or insertable medical device is provided which contains the following: (a) a substrate, (b) a therapeutic agent-containable region disposed over the substrate, (c) a nanoporous polymeric layer disposed over the therapeutic agent-containable region and (d) a macroporous non-polymeric layer disposed over the nanoporous polymeric layer. The nanoporous polymeric layer largely regulates transport of species between the therapeutic agent-containable region and the exterior of the device. The macroporous non-polymeric layer has a larger pore size than the nanoporous polymeric layer and largely serves to isolate the polymeric material from surrounding tissue during in-situ delivery of the therapeutic agents.

  • Patent number: 8734831
    Abstract: A method for manufacturing a porous ceramic scaffold having an organic/inorganic hybrid coating layer containing a bioactive factor includes (a) forming a porous ceramic scaffold; (b) mixing a silica xerogel and a physiologically active organic substance in a volumetric ratio ranging from 30:70 to 90:10 and treating by a sol gel method to prepare an organic/inorganic hybrid composite solution; (c) adding a bioactive factor to the organic/inorganic hybrid composite solution and agitating until gelation occurs; and (d) coating the porous ceramic scaffold with the organic/inorganic composite containing the bioactive factor added thereto. In accordance with the method, the porous ceramic scaffold may be uniformly coated with the organic/inorganic hybrid composite while maintaining an open pore structure, and stably discharge the bioactive factor over a long period of time.

  • Patent number: 8734837
    Abstract: The development and growth of oviparous species such as birds is enhanced by in ovo administration of an enteric modulator such as HMB. The enteric modulator is administered into the amnion, where it is then orally ingested by the subject. The enteric modulator enhances the enteric development of the subject prior to hatch, and enhances the growth of the animal before and after hatch.
