Patent number: 8906391Abstract: Disclosed is a thermorod capable of actively releasing drugs according to temperature of the thermorod and a method of manufacturing the same. The thermorod generates heat by eddy current loss and hysteresis loss in an induced magnetic field. The thermorods can effectively administer drugs, such as anti-cancer drugs, since the thermorods may be used to perform local hyperthermia at 36.5° C. or above and to actively control the active drug release and delivery according to temperature as well. The thermorods may be useful in the treatment of resting tumor cells along with hyperthermia by performing a surgical operation on lesion sites of biological tissues. Using the thermorod, the drug is effectively delivered to an affected part in response to the active drug release. This can minimize the toxicity caused by an increase in blood drug concentration, which occurs when a drug is administered by a conventional method.Type: GrantFiled: October 20, 2010Date of Patent: December 9, 2014Assignees: Korea Sangsa Co., Ltd.Inventors: Young Kon Kim, Jae Geun Park, Sang Guon Lee, Woon Sub Baek

Corticosteroid microparticle formulations are administered locally as a sustained release dosage form (with or without an immediate release component) that results in efficacy accompanied by clinically insignificant or no measurable effect on endogenous cortisol production.Type: ApplicationFiled: December 16, 2013Publication date: August 28, 2014Applicant: FLEXION THERAPEUTICS, INC.Inventors: Neil Bodick, Robert C. Blanks, Anjali Kumar, Michael D. Clayman, Mark Moran

Patent number: 8808745Abstract: A pharmaceutical composition for controlled release of an active substance is provided. The active substance is released into an aqueous medium by erosion of at least one surface of the composition. The composition comprises i) a matrix comprising a) polymer or a mixture of polymers, b) an active substance and, optionally, c) one or more pharmaceutically acceptable excipients, and ii) a coating.Type: GrantFiled: August 23, 2013Date of Patent: August 19, 2014Assignee: Egalet Ltd.Inventors: Gina Fischer, Daniel Bar-Shalom, Lillian Slot, Christine Andersen

Patent number: 8802125Abstract: 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.Type: GrantFiled: July 21, 2006Date of Patent: August 12, 2014Assignee: ARIANNA Medical DevicesInventors: Gaetano Marenzi, Adele Bolognese, Luigi Califano, Antonio Calignano, Umberto Costantino, Gilberto Sammartino, Vittoria Vittoria

Patent number: 8802626Abstract: Disclosed herein are improved osteogenic devices and methods of use thereof for repair of bone and cartilage defects. The devices and methods promote accelerated formation of repair tissue with enhanced stability using less osteogenic protein than devices in the art. Defects susceptible to repair with the instant invention include, but are not limited to: critical size defects, non-critical size defects, non-union fractures, fractures, osteochondral defects, subchondral defects, and detects resulting from degenerative diseases such as osteochondritis dessicans.Type: GrantFiled: March 18, 2011Date of Patent: August 12, 2014Assignee: Stryker CorporationInventors: David C. Rueger, Marjorie M. Tucker, An-Cheng Chang

Patent number: 8802145Abstract: The invention relates to a method of manufacture of fast-disintegrating solid dosage forms, characterized in that one or more structure building components in mixed solid powder form are dosed into cavities of blister packs or moulds, the remaining components dissolved in water dosed and added to the powder to form a moistened, plasticized mass, frozen to below ?20° C., and the water sublimed in high vacuum. In this way solid dosage forms are obtained with a similar porous structure as usually result from freeze drying processes, but the process requires much less water, which means considerably less time and less energy.Type: GrantFiled: October 27, 2005Date of Patent: August 12, 2014Assignee: Pantec AGInventor: Kurt Heinz Bauer

Patent number: 8802146Abstract: A blended electrophilic material with a first component having a functionality of at least three and a second component having a functionality of two is mixed with a nucleophilic material. The blended electrophilic material cross-links with the nucleophilic material to form a non-liquid, three dimensional structure which can applied, e.g., as an adhesion barrier.Type: GrantFiled: March 9, 2007Date of Patent: August 12, 2014Assignee: Neomend, Inc.Inventors: Charles Vaughn Cassingham, William Jerome Mezger
